Markus

Markus is a markdown editor for the people who live in .md. Specs, agent files, AGENTS.md, CLAUDE.md, prompts, READMEs, notes, your work is already markdown. We built Markus to edit it where it lives. Point it at a folder you already have. It becomes a workspace. No import. No copy. No vendor format. It edits your real .md files in place. No cloud. No account. No telemetry. Local-first by default, not as an option. macOS and Windows ~16 MB. Built with Tauri and Rust. (Linux coming!) One-time license. 14-day free trial. No card. There is no AI inside Markus. We sell to people who use AI tools all day, Claude Code, Cursor, agents and we believe the editor for the files those tools read should be calm, native, and yours. We're not adding LLM calls.Give it a try ! www.getmarkus.app
