Cogito (pronounced koh-gee-toh) is a native macOS Markdown editor built by Fabrizio Rinaldi, creator of Typefully. Born from frustration: Obsidian is powerful but overwhelming, iA Writer is beautiful but feels like a different era.
What makes it different
Native Mac app. Fast. No Electron. Syntax dimming instead of heavy highlighting. Feels like a proper macOS citizen.
Features: Quick Open search, tabs, favorites, synced scrolling between source and preview, smart lists, formatting shortcuts. Notes are plain .md files on disk - compatible with any tool or workflow.
Supports wiki-links, embeds, image drag-and-drop, clickable tasks, and real-time external updates. Works well with agents and scripts that modify your files.
AI integration
Built with AI workflows in mind. Compatible with tools that read and write Markdown files. Good fit alongside Claude Code or similar agents that work with local files.
Pricing
Free public beta as of April 2026. Side project for the creator, so expect it to stay lightweight.
