Filo
An ergonomic, local-first Markdown reader designed for professionals who work with documentation every day.
Read Markdown, Beautifully
Filo renders Markdown files with clean, readable typography — right on your Mac. No browser tabs, no cloud sync, no distractions. Just open a file and read.
Built with SwiftUI and native macOS frameworks, Filo launches instantly and feels like a natural part of your system. It's the Markdown reader that gets out of your way.
Features
Everything you need to work with Markdown files, and nothing you don't.
Full-Text Search
Find any text across your document instantly. Search results are highlighted in context with match-by-match navigation using keyboard shortcuts. Search works across rendered content and inside Mermaid diagrams.
Mermaid Diagrams
Filo renders Mermaid diagram syntax directly — flowcharts, sequence diagrams, state machines, pie charts, and more. No plugins or configuration required.
Keyboard-Driven
Navigate with standard macOS shortcuts. Open files, search, move between matches, zoom in and out — all without reaching for the mouse.
Completely Offline
Filo works without an internet connection. Your files never leave your machine — no cloud uploads, no telemetry, no accounts. Open a file and start reading.
Adaptive Themes
Choose between warm and cool color temperatures. Filo respects your system appearance settings and provides a comfortable reading experience in both light and dark modes.
Native Performance
Built with Swift and SwiftUI for macOS. Filo launches in under a second and renders documents instantly. Minimal memory footprint, maximum responsiveness.
Availability
Filo is currently in active development and approaching its initial release.
Requires macOS 15.0 (Sequoia) or later.
