What is DiaCare AI
DiaCare AI is the second product from Vyoma Group — an AI companion specialised for diabetes education and awareness.
Built by Vyoma Group
DiaCare is built by the same small team that built Arka AI. The model underneath is Arka Helix 1, the same wrapper model that powers Arka.
Purpose
Over 100 million Indians and 500 million people globally live with diabetes. Most get a 15-minute appointment every few months and navigate the rest alone. DiaCare is the friend in your pocket who actually understands the disease — never replacing your doctor, always preparing you better for the next visit.
DiaCare is not a doctor
Important: DiaCare does not diagnose, prescribe, or replace medical professionals. See What DiaCare will & won't do for the full safety stance.
Quick Start
Get useful answers in under a minute.
1. Open the app
Visit diacare.vyomagroup.online. No signup. No credit card. The chat box is right there.
2. Ask anything
Type a question and hit send. Examples that get great answers:
- "My HbA1c is 7.4. What does it mean?"
- "What should I eat for breakfast if I have Type 2?"
- "How do I bring my fasting sugar down?"
- "Is karela actually good for diabetes?"
3. Fill your health profile (optional but powerful)
Click the user icon on the left sidebar. Fill in basic info — name, age, type of diabetes if known, recent readings, medications. Every future chat will personalise around these.
The profile lives in your browser. We never see it on our servers. See How the Profile is Stored.
Understanding the Interface
A quick tour of the DiaCare AI interface.
Left rail
- Home — the chat

"DiaCare AI by Vyoma Group" on the left. A "Complete your profile" pill on the right showing your profile completion percentage — click it to fill in missing fields.
Footer disclaimer
Every screen has a small line at the bottom: "DiaCare AI provides educational info only." That line is clickable — it opens our full safety and privacy guide.
Chatting with DiaCare
Talk to DiaCare like you would talk to a careful friend who happens to be a nurse.
Be specific
Bad: "What should I eat?"
Better: "I have Type 2, HbA1c 7.4, vegetarian, South Indian. What should I eat for breakfast?"
Follow up
Don't treat DiaCare like a search engine. It remembers the conversation. Ask "explain more simply," "what if I am also vegetarian," "give me a 7-day plan based on that."
Asking Good Questions
The patterns that get the most useful answers.
Patterns that work
- "Explain my report" + paste the numbers
- "Is X safe for me?" + your context (type, meds, recent A1c)
- "Why does my sugar do Y after Z?"
- "How do I bring my fasting sugar down without changing medication?"
- "Compare option A and option B for my situation"
- "Help me prepare questions for my next doctor visit"
Patterns to avoid
- "Diagnose me" — DiaCare won't, and shouldn't
- "What medicine should I take?" — that's a doctor's job
- Unsigned panic at midnight — if you have emergency signs, call your local emergency number (112 in India)
Chat History
Your chats are saved locally so you can pick up where you left off.
Where chats are stored
In your browser's localStorage. Not on our servers. Clearing your browser data clears your DiaCare chats too.
Managing chats
Each chat is listed in the left rail with a short title. Click to reopen. Long-press (or right-click) on desktop to rename or delete.
Languages Supported
DiaCare speaks English, Hindi, and Hinglish natively.
You can switch languages mid-conversation. Type in Hindi or Hinglish and DiaCare will respond in the same language. The medical terminology stays accurate across all three.
More languages coming
Tamil, Bengali, Marathi, Telugu, Gujarati are on the roadmap. Voice input for Indian languages is being tuned.
Health Profile Overview
Your health profile is the single biggest thing that makes DiaCare personalised.
Once filled in, every chat references your specifics — type of diabetes, recent readings, medications, lifestyle — without you having to repeat yourself.
What it contains
- Basic info: name, age, gender, height, weight
- Diabetes type (if applicable): Type 1, Type 2, Gestational, Prediabetes, At-risk
- Recent blood sugar logs
- Current medications
- Symptoms you've mentioned
What Profile Fields Mean
Every profile field has a clear purpose. Here's why each matters.
| Name | So DiaCare can address you naturally |
| Age | Risk thresholds and recommendations vary by age |
| Gender | Affects waist-circumference and risk thresholds |
| Height & Weight | BMI calculation (South Asian-adjusted) |
| Diabetes Type | Type 1, 2, gestational, or prediabetes — advice differs significantly |
| HbA1c | Anchors the conversation about your 3-month average |
| Recent readings | Lets DiaCare comment on your own trend, not generic ranges |
| Medications | Critical for hypo warnings and timing advice |
| Dietary preference | Veg / non-veg / Jain / vegan — shapes meal suggestions |
| Activity level | Sedentary / light / moderate / heavy — informs exercise advice |
How the Profile is Stored
Your profile lives in your browser. Not on our servers.
How storage works
When you save profile info, it goes to your browser's localStorage. Every time you send a chat message, DiaCare attaches your profile to that message and sends just-in-time. We never store the profile on our server — it lives and dies with your browser session.
What this means in practice
- Clearing your browser data clears your profile
- Switching devices won't carry the profile (sync is on the roadmap)
- Nobody at Vyoma Group has access to your profile
- No tracker, ad network, or third party sees it
Types of Diabetes
Diabetes is not one disease — it's a family of conditions, all involving blood sugar regulation.
Type 1
Autoimmune. The body destroys its own insulin-producing beta cells. Usually diagnosed in childhood or young adulthood. Requires insulin for life. Roughly 5% of all diabetes.
Type 2
Insulin resistance + beta cell fatigue. Develops over years. Strongly linked to genetics, weight, and lifestyle. About 90% of diabetes cases. Can go into remission with significant lifestyle change. See Type 2, Explained.
Gestational
Develops during pregnancy. Usually resolves after delivery but doubles future Type 2 risk. See Gestational Diabetes.
Prediabetes
Not yet diabetes — but a clear warning. Reversible with diet and exercise. See Prediabetes — the Warning.
Rare forms
- MODY — rare genetic, often misdiagnosed as Type 1 or 2
- LADA — slow-onset autoimmune in adults, often initially looks like Type 2
- Steroid-induced — from long-term steroid use
Type 2, Explained
Type 2 is what most people mean when they say "diabetes." Here's how it actually works.
The mechanism
Your body breaks down food into glucose (sugar) that travels in your blood. To move that glucose from blood into cells, you need insulin — a hormone made by the pancreas.
In Type 2, two things go wrong slowly:
- Insulin resistance — cells stop responding properly to insulin
- Beta cell fatigue — the pancreas overworks, then wears out
Result: glucose stays in the blood. Over years, that high sugar damages blood vessels, nerves, kidneys, eyes, and the heart.
Can it be reversed?
Type 2 can go into remission — that's the right word, not "cure." With significant weight loss, exercise, and diet change (especially within 5 years of diagnosis), many people get HbA1c back into normal range without medication. The biology is still there; remission can end if old habits return.
Prediabetes — the Warning
Prediabetes is your body whispering. Diabetes is when it screams.
The diagnostic ranges
- HbA1c: 5.7% to 6.4%
- Fasting glucose: 100 to 125 mg/dL
- 2-hour OGTT: 140 to 199 mg/dL
Why this is good news
Prediabetes is the most reversible stage. With 5-7% weight loss and 150 minutes of weekly exercise, studies show you can cut your risk of progressing to diabetes by 58%. That's better than any medication.
What to do, in order
- 1. Lose 5-7% of body weight
- 2. Move 30 minutes a day, 5 days a week
- 3. Cut refined carbs (white rice, sweets, sugary drinks)
- 4. Sleep 7-8 hours
- 5. Re-test HbA1c every 6 months
Gestational Diabetes
Gestational diabetes (GDM) affects roughly 1 in 5 pregnancies in India.
Why it happens
Pregnancy hormones make the body more insulin-resistant (this is normal — it helps the growing baby). For some women, the pancreas can't keep up and blood sugar rises.
Screening
In India, the DIPSI test is standard — 75g glucose drink, single 2-hour blood draw, usually at 24-28 weeks. GDM diagnosed if 2-hour value ≥ 140 mg/dL.
Managing through pregnancy
- Diet first — smaller frequent meals, low-GI carbs, lots of vegetables
- Daily walking
- Home monitoring — fasting and 1-hour post-meal
- Insulin if diet alone is not enough
- More frequent ultrasounds
After delivery
Blood sugar usually returns to normal within days. But 50% of women with GDM develop Type 2 within 10 years. Get screened with HbA1c annually. Breastfeeding lowers your future risk.
South Asian Risk Factors
South Asian bodies handle insulin differently. We get diabetes at lower BMIs than other populations.
The "thin-fat" phenomenon
A South Asian person with BMI 23 has roughly the same diabetes risk as a European person with BMI 30. We store fat around the organs (visceral fat) at lower body weights.
Adjusted thresholds for Indians
- BMI 23+ = overweight (vs 25 globally)
- BMI 27+ = obese (vs 30 globally)
- Waist >90cm (men) or >80cm (women) = high risk
IDRS — Indian Diabetes Risk Score
A validated tool that scores risk based on age, abdominal obesity, physical activity, and family history. DiaCare uses IDRS framing in its risk scanner. Ask: "Run a risk check for me using IDRS."
Reading your HbA1c
HbA1c (or A1C) is your blood sugar report card for the last 3 months.
It measures how much sugar has stuck to your red blood cells — whose lifespan is about 90 days. Higher average sugar = higher HbA1c.
The ranges
- Below 5.7% — Normal
- 5.7% to 6.4% — Prediabetes (warning)
- 6.5% or higher — Diabetes (two tests = diagnosis)
- For diagnosed: goal is usually under 7%, individualised
Translating to average blood sugar
- HbA1c 6% ≈ avg 126 mg/dL
- HbA1c 7% ≈ avg 154 mg/dL
- HbA1c 8% ≈ avg 183 mg/dL
- HbA1c 9% ≈ avg 212 mg/dL
- HbA1c 10% ≈ avg 240 mg/dL
Fasting Glucose Ranges
Fasting plasma glucose is the simplest blood sugar test — one blood draw after an overnight fast.
Ranges
- Normal: under 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher (two tests)
Home fasting reading
- Target if diabetic: 80-130 mg/dL
- Wake-up reading higher than 130 often means dawn phenomenon or somogyi effect — talk to your doctor
Post-meal & OGTT
Post-meal (post-prandial) blood sugar shows how well your body handles a meal.
2-hour OGTT
You drink 75g of glucose dissolved in water; blood is drawn 2 hours later.
- Normal: under 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or higher
Home post-meal reading (1-2 hours after eating)
- Target if diabetic: under 180 mg/dL (1 hour), under 140 (2 hours)
- Sustained over 200 = your meal had too many fast carbs OR your medication needs review
Daily Monitoring Basics
A glucometer is the cheapest, most powerful diabetes tool you own.
How often to test
- Diet/exercise only: 2-3 times a week, varying times
- Oral meds: once a day, rotating fasting / pre-meal / post-meal
- Insulin: 3-4 times a day, plus bedtime
- GDM: 4 times a day — fasting + 1 hour after each meal
Log usefully
A number without context is useless. Record: time of day, reading, before/after meal, what you ate, activity/stress/sleep notes. Patterns emerge in 2-3 weeks.
Paste your log into DiaCare and ask "spot the patterns" — it will identify foods that spike you, the times that don't, and what your doctor should see.
The Indian Diabetic Plate
"Eat healthy" is useless advice. "Half plate sabzi, one katori dal, one roti" is a meal you can have.
The plate method, applied to Indian food
- Half plate — non-starchy vegetables. Palak, methi, bhindi, lauki, cabbage, beans, capsicum, salad.
- Quarter plate — protein. Dal, chicken, fish, paneer, eggs, tofu, sprouts. Palm-size meat or one katori dal.
- Quarter plate — whole grain or starch. One roti OR half cup rice OR one small sweet potato. Not all three.
Plus a katori of plain curd or buttermilk for gut health.
Portions in Katoris & Cups
Portion sizes in everyday Indian units.
| 1 roti | palm-sized, single thickness |
| 1 katori dal | 120-150 ml (a tea cup is roughly the same) |
| 1 cup rice | ~200g cooked; aim for ½ cup |
| 1 idli | ~60g; 2 idlis with sambar = balanced |
| 1 dosa | medium = ½ a typical plate; eat one with sambar |
| 1 fistful nuts | ~30g — almonds, walnuts, peanuts |
| 1 small banana | ~100g; one per day max |
| 1 small mango slice | ~50g; whole mango = 2-3 portions |
Practical Food Swaps
Small swaps that lower glycemic load without removing pleasure.
| White rice | → Brown rice, millets, foxtail rice |
| Maida roti / naan | → Atta roti, missi roti, jowar bhakri |
| Aloo bhaji | → Palak, lauki, or bhindi |
| Sugar in chai | → Stevia, or no sugar; jeera water alternative |
| Sweets | → Small portion of jaggery-based; or fruit |
| Fried snacks | → Roasted chana, sprouts chaat, makhana |
| Cold drinks | → Buttermilk, lemon water, infused water |
| White bread | → Multigrain or 100% atta bread |
Fruits & Sweets
Most fruits are fine for diabetics in moderation. Fruit juice is not.
Safer fruits
Apples, pears, oranges, guava, papaya, berries, watermelon (small portions), kiwi.
Watch portions
Mango, banana, chikoo, grapes — small portions only. Half mango, half banana, ~10 grapes.
Skip
- All fruit juices (concentrated sugar without fibre)
- Dried fruits in large quantities
- Canned fruits in syrup
Exercise — the Cheapest Medicine
No medicine for diabetes works better than movement.
How much
30 minutes a day, 5 days a week, of moderate activity. Lowers HbA1c by 0.6-0.7% — comparable to many drugs.
What "moderate" means
- Brisk walking (3-4 km in 30 minutes)
- Cycling on flat ground
- Swimming steady
- Dancing
- Beginner yoga (Surya Namaskar)
The post-meal walk hack
10-15 minutes of walking after lunch and dinner drops post-meal sugar by 20-30 mg/dL. Muscles literally pull glucose out of the blood. Free. No equipment. Works immediately.
Daily Routine that Works
A repeatable daily structure quietly does the heavy lifting.
Morning
- Wake roughly the same time each day
- 500ml water before anything else
- 20-30 min walk or yoga before breakfast
- Breakfast within 1 hour: half plate veg + paratha OR 2 idlis + boiled egg/dal
Mid-day
- Lunch around the same time daily
- 10-min walk after lunch — non-negotiable
- 6-8 glasses of water across the day
Evening
- Dinner by 8pm if possible
- 15-min walk after dinner
- No screens 30 min before bed
- 7-8 hours of sleep
Sleep, Stress & Sugar
You can eat perfectly and exercise daily, and still see your sugar rise — if you sleep 5 hours and live in chronic stress.
Sleep
A single night of 5 hours sleep raises next-day insulin resistance by 25-30%. Target 7-8 hours, consistent bedtime within 30 minutes daily.
Stress
Cortisol — the long-term stress hormone — tells the liver to release stored glucose. That's why high-stress weeks come with high fasting numbers. Lower cortisol via:
- Daily walking outdoors (sunlight + movement)
- 4-7-8 breathing (4 sec in, 7 hold, 8 out)
- Pranayama or meditation, 10 minutes
- Time off screens
- Social connection
Hydration
Water is the most underrated diabetes medication.
The dehydration cycle
High sugar → kidneys flush sugar out → pull water with it → dehydration → concentrates remaining sugar → cycle worsens. Within hours.
How much
Roughly 30-35 ml per kg body weight. For a 70kg person: 2.1-2.5 litres a day. Spread across the day, not all at once.
What counts
- Plain water, jeera water, infused water, herbal teas, buttermilk, soup
- Half counts: tea, coffee
- Doesn't count: sweet drinks, juices, lassi with sugar
Foot Care
A 5-minute daily foot ritual prevents one of diabetes' worst complications.
Why feet are vulnerable
- Neuropathy — nerve damage means you stop feeling small injuries
- Reduced circulation — small cuts heal slowly, infections take hold
Daily 5-min check
- Inspect tops, sides, soles, between toes
- Look for cuts, blisters, redness, dry cracking, ingrown nails
- Wash with lukewarm water, dry thoroughly between toes
- Moisturise soles and tops, not between toes
- Trim nails straight across
Footwear
- Never barefoot, even indoors
- Check shoes for pebbles before wearing
- Properly fitted — thumb's width between toes and shoe end
- Diabetic socks if you have neuropathy
Medications Overview
Educational only. Your medication is between you and your doctor.
Metformin
First-line for Type 2. Reduces liver glucose output, makes cells more insulin-sensitive. Low cost, safe long-term, no hypo risk. Common side effect: stomach upset early on. Take with food.
Sulfonylureas (glimepiride, glipizide)
Push the pancreas to make more insulin. Cheap but carry hypo risk and slight weight gain. Older class.
DPP-4 inhibitors (sitagliptin, vildagliptin)
Help gut release more of its own insulin after meals. Weight-neutral, well-tolerated, modest A1c effect.
GLP-1 agonists (semaglutide, liraglutide, tirzepatide)
The class changing diabetes care. Powerful A1c reduction, significant weight loss, cardiovascular protection. Injectable, some now oral. Side effect: nausea early on. More expensive.
SGLT2 inhibitors (empagliflozin, dapagliflozin)
Make kidneys flush extra sugar into urine. Weight loss, BP-lowering, heart and kidney protection. Watch for UTIs, dehydration.
Insulin
Many types: rapid, short, intermediate, long-acting, mixed. Required in Type 1, used in Type 2 when needed. Hypo is the main risk — understand the symptoms.
Insulin Basics
If you're on insulin, the rules change a bit. Here are the basics.
Insulin types
- Rapid-acting — starts in 15 min, peaks at 1 hr (with meals)
- Short-acting — starts in 30 min, peaks at 2-3 hr (with meals)
- Intermediate — starts in 1-2 hr, peaks at 4-12 hr (basal)
- Long-acting — flat profile, lasts 24 hr (basal)
- Mixed — preset combination of two
Rules to follow
- Always have glucose tabs / something sweet on you
- Rotate injection sites — don't inject the same spot daily
- Store unopened pens in fridge; opened pens at room temp (check brand)
- Never share pens, even with family
- If you skip a meal after taking rapid-acting, your sugar will drop — eat something
Timing & Adherence
Timing matters as much as the dose.
General rules
- Metformin: with meals (especially largest meal) to reduce stomach upset
- Sulfonylureas: usually 30 minutes before meals
- DPP-4 inhibitors: any time of day, same time daily
- SGLT2 inhibitors: in the morning (to avoid nighttime urination)
- Long-acting insulin: same time every day (morning or evening)
- Rapid-acting insulin: usually 5-15 minutes before meals
Missed a dose?
Don't double the next one. Take the missed dose if it's close to the scheduled time; otherwise skip it. Ask your doctor about your specific medication.
Hypoglycemia Rescue
Low blood sugar is the one diabetes complication that can hurt you in minutes.
Early warning signs
- Sudden desperate hunger
- Shakiness, trembling hands
- Sweating without reason
- Heart racing
- Anxiety or irritability
- Headache
- Tingling lips or tongue
- Sudden tiredness or fuzzy thinking
The 15-15 rule
If under 70 mg/dL (or symptoms severe and you can't test):
- 1. Eat 15g fast carbs: 3 glucose tabs, ½ cup juice (not diet), 1 tbsp sugar in water, 3 boiled sweets
- 2. Wait 15 minutes
- 3. Re-test. If still under 70, repeat
- 4. Once stable, eat a small protein/carb snack to prevent another drop
Severe hypoglycemia — call emergency
If the person is confused, unable to swallow, having a seizure, or unconscious: do not give food or water orally. Call emergency services (112 in India). If you have glucagon, give it now. Place them on their side.
DKA Awareness
Diabetic Ketoacidosis (DKA) is a medical emergency.
What is DKA?
When the body has very little insulin, it can't use glucose. It burns fat instead and produces ketones — acidic chemicals that build up in the blood.
Warning signs
- Very high blood sugar (over 250 mg/dL)
- Vomiting and nausea
- Fruity-smelling breath
- Rapid, deep breathing
- Confusion or extreme tiredness
- Severe abdominal pain
- Dry mouth and skin
What to do
Call emergency services (112 in India) immediately. DKA can be fatal within hours. This is not a "wait and watch" situation.
Who is at risk?
Most common in Type 1 diabetes, especially when insulin is missed or during illness. Can also occur in Type 2 if SGLT2 doses are missed during illness. Always tell your doctor when you're sick.
Emergency Signs
Call your local emergency number (112 in India) immediately if you experience any of these.
- Chest pain or pressure, especially with sweating or shortness of breath
- Sudden weakness or numbness on one side of the body
- Slurred speech or sudden confusion
- Loss of consciousness or seizure
- Severe vomiting with very high blood sugar (suspect DKA)
- Fruity-smelling breath with confusion and rapid breathing
- Severe hypoglycemia — person can't swallow or is unresponsive
- Sudden vision loss or severe vision change
Diabetes can mute classic warning signs. When in doubt, call. Better an unnecessary trip than a missed event.
When to See a Doctor
DiaCare is a great companion. It is not a doctor. Six situations where in-person care is non-negotiable.
1. Newly suspected diabetes
Classic symptoms — persistent thirst, frequent urination, unexplained weight loss, blurry vision, recurrent infections — book a doctor visit and get a blood test.
2. Persistent very high sugar
Multiple readings over 250 mg/dL across days, especially with fatigue or nausea. Call your doctor today.
3. Recurring lows
More than 1-2 hypos per week, or any severe hypo. Medication adjustment is needed.
4. Foot wound that's not healing
Any cut, blister, or sore that doesn't improve in 1-2 days. See doctor within 24 hours.
5. Pregnancy planning or pregnancy
See a diabetologist and obstetrician. Specialised care matters.
6. Any emergency sign
See Emergency Signs. Call now.

For Parents & Minors
DiaCare AI is intended for users aged 13 and above.
Children with diabetes should be guided by parents and pediatric endocrinologists. DiaCare can support a parent's understanding but never replaces specialist care for a minor.
For parents
- Use DiaCare to learn alongside your child
- Always confirm decisions with the pediatric team
- Be especially careful with hypoglycemia in young children — they often can't describe symptoms
- Track foods, school activity, and emotions — all affect sugar
For Pregnancy
If you are pregnant or planning pregnancy, please tell your doctor.
DiaCare can answer general questions about gestational diabetes but pregnancy-specific care must come from your obstetrician.
What DiaCare can help with during pregnancy
- Understanding GDM screening tests (DIPSI, OGTT)
- General diet guidance (always confirm with your obstetrician)
- Understanding why post-meal targets are tighter in pregnancy
- Preparing questions for your next prenatal visit
What DiaCare cannot help with
- Insulin dose decisions during pregnancy
- Whether a specific food or medication is safe for your baby
- Interpreting fetal growth scans
Powered by Arka Helix 1
DiaCare AI runs on Arka Helix 1, Vyoma's flagship wrapper model.
What is Helix 1?
Helix 1 is a carefully-composed wrapper around a high-quality open-weights foundation model. It adds Vyoma's personality layer, memory + safety overlay, and a topic-specific system prompt tuned for the product.
For DiaCare specifically
Helix 1's system prompt is heavily tuned for diabetes education, South Asian context, Indian foods and units, and conservative safety. The prompt is ~6,500 characters and includes explicit refusal patterns for diagnosis and prescription.
Why a wrapper, not a custom-trained model?
Training a foundation model is expensive, slow, and a research problem. The product problem — making intelligence feel safe, helpful, and India-aware — lives in the wrapper. By focusing engineering on the wrapper, every improvement to the underlying foundation reaches DiaCare users automatically.
The System Prompt
The system prompt is what makes DiaCare DiaCare, not generic AI.
What's in the prompt
- Identity (who DiaCare is, who built it)
- Tone rules (short, conversational, no preamble)
- Response style (3-6 lines for normal questions, longer only when asked)
- Disclaimer rules (only when interpreting reports or symptoms)
- What DiaCare can do (education, risk, food, reports, monitoring, etc.)
- Health profile injection format
- Safety boundaries (non-negotiable)
- Emergency escalation triggers
- Indian-context specialisations (foods, units, IDRS)
Iteration
The prompt is reviewed and tuned regularly. Improvements roll out via Cloudflare Worker updates — no app reinstall needed.

Knowing what DiaCare won't do is as important as knowing what it will.
What DiaCare will do
| ✓ | Explain diabetes types, mechanisms, complications in plain language |
| ✓ | Help you understand lab reports (HbA1c, fasting, OGTT) |
| ✓ | Suggest meal patterns and portion sizes for Indian context |
| ✓ | Walk through risk assessments (IDRS-aware) |
| ✓ | Provide lifestyle guidance: exercise, sleep, stress, foot care |
| ✓ | Help prepare questions for doctor visits |
| ✓ | Correct common diabetes myths with evidence |
What DiaCare will never do
| ✗ | Diagnose any disease |
| ✗ | Prescribe medications or change doses |
| ✗ | Replace your doctor |
| ✗ | Give emergency medical advice (always escalate to 112) |
| ✗ | Make treatment decisions for you |
Common Issues
A few things that occasionally trip people up.
Response feels slow
Adaptive thinking takes longer than a normal response. If you didn't intend to enable it, check the model selector. Also: during peak hours (8-10pm IST) the model may be slower — an upgrade path is on the roadmap.
Profile not saving
Make sure your browser allows localStorage. Private/incognito mode wipes localStorage on close. Check that you have at least 5MB of available storage.
Wrong language
DiaCare follows whatever language you start a conversation in. Type your next message in your preferred language — it will switch.
Tips popup appears repeatedly
That means the backend is rate-limited or unavailable. Wait a minute and try again. The popup links you to the pricing page in case you want priority access (coming soon).
