Local files, offline
Open a real project folder and keep editing without a network or account. Finder, Git, and AI tools still read the same files.
Local Markdown editor for Mac
A local Markdown editor built around real files.
Fylune edits ordinary local files, works offline, manages assets, and renders the parts of Markdown that basic editors leave behind. The core editor is free.
Free core editor
Open, edit, search, and organize local Markdown and MDX files for $0. This is the product, not a timed trial.
Automatic asset paths
Drop or paste images, video, and documents. Fylune files them locally and writes a portable relative path.
Complete Markdown rendering
Work with Mermaid diagrams, mind maps, formulas, tables, tasks, media, code, and MDX blocks in one document.
Reviewable AI changes
See what changed, accept what helps, and keep control of the final file.
Conflict-safe writes
Every write checks the expected content first. A mismatch pauses for review instead of overwriting.
Designed around trust
AI can move fast. Your source files deserve a seatbelt.
- 1Read
Fylune captures the exact source the change was based on.
- 2Propose
The edit is shown as a reviewable change, not a magic replacement.
- 3Check
Before writing, Fylune verifies the file has not changed underneath it.
- 4Write or review
Matching content writes atomically; mismatches become explicit conflicts.
