Your documents. Your files.
Ready for AI.

Edit the Markdown, MDX, and images already inside your project in a calm document workspace. Keep every AI agent and local tool working with the same files.

Create with context

Start a document beside the files that already explain the project.

Local, private, offline

Keep work on your Mac. Keep working offline.

Fylune opens the Markdown and MDX files already inside your folders and edits them locally. No account is required for the core writing loop.

Local source of truthOrdinary files remain readable by Finder, Git, and AI tools.
Offline by defaultOpen, edit, and search without waiting for a network.
No account requiredYour core editor does not depend on a cloud login.

Free core editor

The editor costs nothing.

Basic local editing is completely free: open folders, write, search, organize assets, and render the Markdown you already have.

Unlimited local documents Markdown and MDX editing Search and file navigation Built-in components

Paid plans are for optional cloud and advanced collaboration services, not access to your local files.

Automatic asset management

Drop the asset. Keep writing.

Paste an image or add a video. Fylune stores it with the project and writes the relative Markdown path, so local files keep working without URL housekeeping.

Drop or paste
Bring in an image, video, or document from the way you already work.
Fylune files it
The asset is copied into the project, beside the Markdown that uses it.
The link just works
Fylune writes and resolves the relative path for you.

Complete Markdown

Markdown, fully awake.

Render and edit the parts that usually send you back to an IDE: Mermaid flowcharts, mind maps, KaTeX formulas, tables, checklists, media, and richer MDX blocks.

Edit Markdown directly. Diagrams render with Mermaid and formulas with KaTeX. MDX and JavaScript never execute in this preview.
