LOCAL FIRST. YOUR CHOICE.
Your library.
Your space.
Your books and notes live on your device. Connect your own model service when you want AI alongside you.
- No Folio account needed to start reading.
- API keys stay in memory, or are encrypted locally when you choose to save them.
- AI requests send the question and relevant source context to your chosen service.
- Automatic conversation notes are optional and off by default.
AI needs your own API key. Model usage is billed by your provider. This website uses no analytics or advertising cookies.

Release notes & checksums ↗A FEW THINGS TO KNOW
Before you begin.
How do I get started?
Open the downloaded setup file. Choose a language, an installation folder and whether to create a desktop shortcut. Open Folio from the Start menu or shortcut, then connect your document folder. To use AI, add your own API key in Settings.
Can I use it without AI?
Yes. Reading, the local library, annotations and notes work without a model key. AI explanations and generated concept maps need your own model service.
What does this beta support?
PDF, TXT and Markdown, with Chinese and English interfaces. Text-based PDFs support passage selection; scanned pages do not have OCR yet. The 3D experiment covers tetrahedral rotations, not arbitrary generated scenes. macOS, Linux and Zotero sync are not available yet.
How do I update or send feedback?
Close Folio and run the newer installer in the existing location. Uninstall from Windows Settings; personal documents, notes and settings are kept. Export important notes regularly. For problems or suggestions, open an issue on GitHub. Avoid posting private documents or API keys.
