The problem
You have a prescription. The first chemist doesn't have one of the medicines. Neither does the second.
Apps that list pharmacy stock don't fix this, because small chemists can't keep a stock database up to date.
How it works
Step 1
Ask the pharmacist instead
The customer confirms a list and shares a location. The request goes to the nearest approved, open pharmacies at the same time. Each pharmacist marks every item: have it, by tomorrow, other brand, or no.
Step 2
One message that updates itself
Answers edit a single board message in the customer's chat, ranked as they arrive. The customer reserves the best shop, or splits the list across two, and gets a 4-digit pickup code.
Step 3
One brain
Every rule, permission and state change lives in one domain module on SQLite. Telegram, the web app and the demo all call it, so they can't disagree.
Step 4
Careful by design
Pharmacies see the list and the distance, not who you are. Prescription photos are read once and thrown away. Habit-forming medicines are never broadcast.
The hard parts
- Never guessing a strength
- A brand name must agree with any strength, form or release type the user typed. A mismatch returns the variants that do exist, and nothing is swapped silently.
- State that can't drift
- Asks, recipients and reservations are small state machines. Repeating a transition is harmless and anything else is rejected, so a double tap never double-books.
- Saying how sure it is
- Pharmacist answers are marked confirmed. Map results say stock unknown. Online pharmacy links say not checked. No source pretends to know more than it does.
The proof
- 43 automated tests cover the domain rules and full Telegram conversations, and CI runs them on every push.
- The first version, MediFast AI, was a team prototype with a 169K+ medicine catalogue and Hinglish search. It reached the Cognizant Technoverse 2026 Grand Finale: Top 24 of 2,000+ teams.
- A one-minute local demo runs the real bot with a customer, a pharmacist and an admin side by side.
Honest statusMediFast is a 7th-semester major project, not a pharmacy. The pharmacies in the demo are fictional, and a pilot with real ones is the next step.
