<a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="https://getmarkus.app">Markus</a> is a markdown editor for the people who live in .md. Specs, agent files, <a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="http://AGENTS.md">AGENTS.md</a>, CLAUDE.md, prompts, READMEs, notes — your work is already markdown. We built <a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="https://getmarkus.app">Markus</a> to edit it where it lives. Point it at a folder you already have. It becomes a workspace. Your real .md files, edited in place. No import, no copy, no vendor format. Everything stays on your machine. Local-first by default, not as an option. Built-in MCP server. Your agents — Claude Code, Cursor, anything that speaks MCP — read and write your workspace directly, no plugins, no glue code. 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 <a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="https://getmarkus.app/en">Markus</a>. We just open the door for the AI tools you already use. We sell to people who use AI tools all day and we believe the editor for the files those tools read should be calm, native, and yours. We're not adding LLM calls. We're adding the plug that lets your agents reach your files, cleanly. Give it a try! <a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="http://www.getmarkus.app">www.getmarkus.app</a>
