Uniichat

Uniichat is an AI agent chat application with a single continuous conversation that uses a memory tree.

UniiChat is an AI agent with a continuous chat interface that never ends and requires no new chat buttons. Messages are summarized and organized into a binary memory tree where detail fades with age but nothing is lost. Users can zoom into any summary line down to the original message, preventing context rot and compaction data loss. It supports running shell commands, reading and editing files, driving a Mac screen, and spawning background subagents. Users can import past Claude and ChatGPT chats into the tree. The system runs via self-hosted servers using Bun with Anthropic or OpenAI API keys, accessed through a browser or terminal.
