Fibrae is a visual, canvas-based notes app for people whose thinking doesn't fit into a single document.

Spread your notes, ideas, and research across as many canvases as you need, and connect them the way your thinking actually works — not the way a folder structure forces it to. Drag cards, link them, group them, and step back to see the shape of what you're working on.

WHAT MAKES FIBRAE DIFFERENT

• Your work stays on your device. Fibrae is local-first: your canvases live in your own storage, not on someone else's server.

• Ask questions across everything you've written. Fibrae's built-in AI chat can read across every canvas in scope and answer questions no single note could — what theme keeps coming up, which cards belong together but aren't linked, what's closest to being finished.

• Bring your own AI. Connect Anthropic, OpenAI, Google, OpenRouter, Groq, DeepSeek, Mistral, or a locally-run model — whichever you already use or trust. Your notes are sent directly to the AI provider you choose, using your own key; Fibrae's own servers never see them.

• No sign-in wall to try it. Start using Fibrae immediately.

GETTING STARTED

Fibrae is free to try for 14 days, in full — every feature, no card required. After the trial, continuing costs $5.99/month, billed and managed through Google Play. Cancel any time from your Play Store subscriptions.

Even if you decide not to continue, your work is never held hostage — Fibrae writes out everything you made as an open, readable file before locking anything, so it's always yours to keep.

PRIVACY

Fibrae doesn't track you, and there are no ads and no analytics. The only data that ever leaves your device is what you choose to send to an AI provider when you use the chat feature — and that's entirely optional.
