13 Mar 2024Writed: A Private AI Journal That Runs in Your Browser
Writed is a markdown journal with a built-in AI assistant that runs entirely on your device. You write your entries, then ask the AI questions about your own thoughts—and none of it ever leaves your browser tab. No account, no cloud upload, no tracking.
Most “AI journal” apps ship your most private writing off to a server for embedding and inference. Writed flips that: the embeddings and the chat model both run locally, so your journal stays yours.
How It Works
You write entries in a clean markdown editor, organized by date, and they auto-save locally as you type. Behind the scenes, Writed indexes those entries on-device so they become searchable.
When you ask a question, it runs a hybrid retrieval over your own entries and answers with citations—pointing you back to the exact entries and dates the answer came from. All of that retrieval and generation happens inside the browser tab using WebGPU and WebAssembly, with local embedding and chat models.
What Makes It Different
- On-device AI — local embeddings and chat; your writing never leaves the browser.
- Markdown, date-based entries — simple, fast, and yours.
- Retrieval with citations — answers grounded in your real entries, with sources and dates.
- Offline-first — works without a connection after the initial load.
- Own your data — export the whole journal as a ZIP of plain markdown files anytime.
- No account required — open it and start writing.
- Open source — released under the MIT license.
It’s free and permanently so for a single device—unlimited entries, on-device AI, and full export. A planned Pro tier ($5/month) adds end-to-end encrypted cloud sync, multi-device access, and automatic backups, without giving up the privacy model.
Writed is a practical demonstration of how far in-browser AI has come: real retrieval-augmented chat over personal data, with zero server round-trips.
