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

Private by design*

Your saved places live on the phone. It compares your position with them itself and raises the reminder itself — no request to us, so no record of where you were.

How it works →

Location-aware*

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

* 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 pharmacy, connecting to the home WiFi, rain forecast for tomorrow, or the phone going still. Geofences are worked out on the device itself, so location reminders work without your coordinates leaving your phone. 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.
