What is lettabot?
LettaBot is a personal AI assistant built with the Letta Code SDK that lets you talk to the same agent across Telegram, Slack, Discord, WhatsApp, and Signal. It remembers conversations from all channels in a single memory, and can read files, search code, and run commands on the user's computer. It periodically checks for things to do with a heartbeat and schedules reminders and recurring tasks. However, according to the official repository, it is no longer actively maintained, and new development takes place in Letta Code's Channels and Remote Environments.
