A few things to know

The trial lasts 30 days and includes all desktop features. After it ends, you can still view and export existing data; adding and editing content will stop. Bring your own AI key; model provider charges are separate.

One license covers 3 devices, with self-service unbinding, a permanent desktop license, and lifetime desktop version updates. Future SaaS sync and other services are excluded. The standard license is $39 USD, paid once. Buy securely through Dodo Payments.

Your vault lives in a local folder you choose. Documents are Markdown files, with a local database for indexing. You can back up the vault yourself. When you use AI, relevant content is sent to your selected model provider.

Configure a compatible model provider and your own API key. Your API key is stored locally and sent only to your chosen AI provider to authenticate requests, not to the Fluid Wiki licensing service. Your provider charges for model usage, and online models require an internet connection. Semantic search also requires an embedding model.

You can read and edit local notes without an online model. Online AI, web search, and downloads require a connection. Local storage does not mean online AI requests stay on your device.

Windows x64 is available through Microsoft Store or a direct installer. macOS is available as a universal DMG for Intel and Apple Silicon. The Mac release is not notarized by Apple and may require manual approval on first launch; see the Mac installation instructions on the download page.
