LettaBot is an autonomous agent and bot framework developed by Letta AI (the creators of MemGPT/Letta). It was designed to run conversational and tool-using agent workflows with persistent memory and execution capabilities across terminal environments and communication channels. In daily operations, LettaBot operates as an orchestration agent that executes tasks using modular skills, file systems (MemFS), and scheduled background jobs. It supports human-in-the-loop tool calling through interactive approval workflows, automated delivery options for cron-based tasks, and voice interfaces alongside standard text prompts. What set LettaBot apart was its deep integration with Letta's stateful memory architecture and background execution tooling, allowing agents to retain context and trigger tasks on a schedule. However, LettaBot has been deprecated and officially archived by Letta AI in favor of Letta's native Channels and Remote Environments infrastructure. LettaBot is open source and hosted as a public archive on GitHub. Because the repository is archived and read-only, it is primarily of historical reference for developers studying MemGPT/Letta agent architectures rather than for active production deployments.
