AI-Powered Telegram Reminders — Triggered by Context, Not Just Time

Private by design*

Your saved places are matched on the phone: it compares your position with them itself and raises the reminder itself, without sending your position. The places themselves are kept in your account so they work on every device.

How it works →

Location-aware*

Arriving at or leaving a saved place — or walking near any supermarket, petrol station, ATM or car park.

How it works →

WiFi triggers*

Works indoors where GPS gives up. Fires the moment you connect to the home or office network, and when you leave it.

How it works →

Time & schedule

Daily, weekdays, weekends — or a monthly date range.

Weather alerts

Rain in Kyiv tomorrow? Get reminded to take an umbrella tonight.

Idle time*

Reminds you when you're free — no more missed low-priority tasks.

AI parsing

Just write naturally in any language — Claude figures out the trigger.

Schedule from a photo

Photograph a school timetable — lessons with times become reminders, the rest are kept as notes.

How it works →

Voice

Dictate a reminder instead of typing it, and hear it read aloud when it fires.

* Needs the Android app. Everything else works in the Telegram bot alone.

Brain Buffer is a context-aware reminder app and Telegram bot. Instead of firing at a time you had to guess in advance, a reminder waits for the moment it is useful: arriving at a place, walking past a supermarket, connecting to the home WiFi, rain forecast for tomorrow, or the phone going still. Saved places are matched on the device itself, so a reminder for one fires without your position being sent; only a “near any supermarket” reminder sends it, and only while you have one. Available as an Android app, a Telegram bot that needs nothing installed, and a web interface — and a family can share reminders without sharing where anyone is.
