bitterbot-desktop vs letta
bitterbot-desktop: Bitterbot is a self-hosted personal agent that keeps memory, identity and learned skills as files and SQLite on your own disk. It works through a real browser, code execution, scheduled jobs and chat apps such as Telegram, WhatsApp, Slack and email, and between conversations it consolidates memories and proposes reusable skills that must pass tests.; letta: Letta is a powerful platform for building stateful AI agents equipped with advanced memory, enabling them to learn and self-improve over time. It provides both a command-line interface for local agent execution and a comprehensive API with Python and TypeScript SDKs for seamless integration into applications.
TL;DR
A personal assistant that remembers past project decisions
- You want a long-lived agent that remembers past work and rewrites its own memory and context over time.
- You want one agent reachable from CLI, desktop, browser, mobile and messaging apps, with subagents, schedules and hooks.
- You want memory you can inspect: the README says context is tracked in git and can sync to your own repository.
- You only need to add memory to an agent you already use through MCP; a small MCP memory server is a lighter fit.
- You rely on older Letta tutorials or the V1 API server: the project restructured, and the V1 server is retired.
- You want everything to work without signing in: Letta Cloud is the default backend and some features need it.
