Privacy
Last updated: 8 July 2026
Weavify is a private notebook that runs in your browser. There is no account, no sign-up, and no tracking. Your notes and chats are stored only on this device, in your browser's local storage (IndexedDB) — we don't have a copy.
What leaves your device depends entirely on which mode you choose for the AI:
On-device (WebLLM) stays on device
The AI model runs inside this browser. Your prompts and notes are never sent anywhere — this mode works fully offline once the model has downloaded.
Your own key (BYO) your account
Your browser talks directly to the AI provider you chose (e.g. OpenAI, Anthropic, a local server), using the key you entered. That key stays in your browser — we never see it, and nothing passes through our servers.
Free tier leaves your device
The free tier is a convenience we fund so you can try Weavify without a key. When it is active, requests pass through our small relay, which adds our operator key and forwards them to OpenRouter (an AI routing service). Two kinds of content are sent this way:
- Chat prompts — the messages and context of the note or conversation you're working on.
- Document / memory text (embeddings) — if you index a document or let Weavify build searchable memory on the free tier, that text is also sent to OpenRouter to be turned into embeddings.
We do not store the contents of your prompts or documents on our server; they are relayed to OpenRouter to generate a response and then discarded. OpenRouter and the underlying model providers process the request under their own terms. If you want zero third-party egress, use On-device or Your-own-key mode instead.
Downloaded models
On-device AI and read-aloud (text-to-speech) download their model files from public content-delivery networks (such as Hugging Face) the first time you use them. Those are ordinary file downloads to your browser; your notes are not included.
What we never do
- No accounts, no advertising, no analytics profiles, no selling data.
- We never log the contents of your prompts, notes, or documents on our server.
- Your BYO API key is never transmitted to us.
