"I've tried every AI writing tool out there. What pulled me in with Cafezin was being able to see exactly what the AI changed — it marks the edits and I accept or reject each one. Finished two chapters in a week without losing my voice."

"I prep my lectures using notes I've been building for years. Now I open them inside Cafezin, ask the AI to structure an outline and turn it into slides — and it actually reads the documents I have open. Saves me two hours of prep per class."

"I was using four different tools: one for notes, one for outlines, one for AI, one for slides. Cafezin replaced all of them. My whole research project in one place, with AI that knows what I'm working on."

Frequently asked

Is Cafezin really free?
Yes. The full Markdown editor, visual canvas, slides, and local file system are free forever — no credit card, no time limit. AI features (drafting, revising, summarising with AI) require a paid plan starting at $5/month, or you can bring your own API key from OpenAI, Anthropic, or GitHub Copilot at no extra charge.
Do my files go to the cloud?
No. Cafezin is local-first — all your documents live on your device as plain Markdown files. There's no mandatory cloud sync and no vendor lock-in. Your files remain fully readable in any text editor, forever.
Which AI models does it support?
Cafezin works with GitHub Copilot, OpenAI's latest models, Anthropic Claude, Google Gemini, and Groq. Paid plans include managed Cafezin AI credits so you don't need your own API key. BYOK (Bring Your Own Key) is always available on any plan.
Does it work offline?
The editor, canvas, version history, and all local-file features work fully offline. AI features require an internet connection to reach the model provider. Your files are never uploaded unless you explicitly send them to AI.
What Mac do I need?
Cafezin requires macOS 13 Ventura or later and runs natively on both Apple Silicon (M1/M2/M3/M4) and Intel Macs. A Windows version is also available on the downloads page.
