What’s new

Version 1.2 · Updated June 24, 2026

What's New in 1.0.2 Share markdown from anywhere — Markdown Mermaid now appears in the iOS share sheet, so you can send a URL from Safari, GitHub, or any browser directly to the app. It automatically fetches and renders the content, including Mermaid diagrams. Also in this update: - Open .md files directly from the Files app or any app that supports "Open In" - GitHub URLs are now automatically converted to raw content before rendering — no more seeing HTML source - Fixed the version number display in the About screen
