Buffy Agent is a personal behavior agent that treats everything you want to change as an activity — habits, tasks and routines — instead of yet another fragmented app.
Why a personal behavior agent?
Most productivity tools start with lists and calendars. Buffy starts with behavior. It is designed to sit next to you across channels you're already using — ChatGPT, Telegram, Slack and internal bots — and manage the full lifecycle of your habits, tasks and routines.
A unified activity model
Under the hood, Buffy uses a single Activity model with three flavors: habit, task and routine. Each activity carries scheduling metadata (intervals, due dates, windows), priority and a simple status log. This uniform structure keeps the core small while still expressive enough to cover daily routines, one-off tasks and ongoing experiments.
Separation of core vs. interfaces
Interfaces like ChatGPT or Telegram are thin adapters. They receive user messages, normalize them into a unified message format and send them into the behavior core. The core owns the logic for parsing intents, updating activities, scheduling reminders and generating insights, which is what allows Buffy to feel consistent across channels.
Built for long-term behavior change
The goal is not just to tick off more todos. The agent is designed for long-term behavioral change: noticing patterns, adapting reminders to your context and nudging you just enough without adding noise. The activity model, reminder engine and memory system all work together to support that outcome.
