01Desktop app

The reading room.

A native app for macOS, Windows, and Linux. Every thread your agents have written, browsable and searchable in one place — with a chat that can read your own history back to you.

Browse & read

Every transcript, legible

Open any session as a clean, rendered transcript — user turns, assistant turns, tool calls folded away. Jump between threads without leaving the app.

Chat

Talk to your archive

A built-in, provider-agnostic chat that can search your own history and run shell commands with your approval. Bring your own key — Anthropic, OpenAI, Gemini, OpenRouter, or Ollama.

Export

Out to Obsidian

Send any thread to your vault as a clean note — optionally with an AI-written summary of the decisions, gotchas, and TODOs buried in it.

Stats

Know your corpus

A dashboard of threads and messages per source and role, your busiest projects, and how much of the archive is embedded for semantic search.

Cleanup

Reclaim the shelves

A paginated, size-aware table to prune old threads and reclaim disk space when the archive gets heavy.

One index

Shared everywhere

The same local index powers the CLI, the editor extension, and the MCP server. Index once; reach it from anywhere.
