Export your data from the platforms that hold it. Import it locally. Browse, explore, and reflect on your own terms.
Sync with Chrome
Install the browser extension. It auto-syncs new ChatGPT, Claude, and Gemini conversations in the background. Rate-limited, completely silent.
Import your sources
Drop in WhatsApp exports, Messenger archives, Google Keep, calendar files, SMS backups, or Instagram DMs. Format is detected automatically. In Notes, choose a folder to import an Obsidian vault. WhatsApp and Spotify can also connect live when you choose.
On-device AI extracts structure
Conversations are segmented into meaningful chunks. A local LLM generates summaries, extracts topics, detects emotions, and identifies key facts. Embeddings power semantic search. Choose your model size. All on your machine.
Reflect with Claude
Claude is embedded in the app and sees only what you allow. Use labels to control which conversations it can access. Ask about patterns, relationships, or decisions. Also works as an MCP server for Claude Desktop. Uses your existing Claude subscription.
Write in Retrace
Keep your journal, notes, tasks, and reflections together in Retrace's authoring surface. Markdown remains an internal boundary.
