MarkSay

Markdown for you and your AI

Only for Mac

Free · In‑App Purchases

Mac

The Markdown editor your AI assistant can drive - local REST + MCP on your Mac, live preview with diagrams and math, one-click export to HTML, PDF, and Word. MarkSay is the Markdown editor your AI assistant can drive. Write in a fast, native editor with live preview: Mermaid diagrams, LaTeX math, tables, task lists, and code render as you type, and an outline sidebar keeps long documents navigable. Export clean HTML, PDF, or Word (.docx) with diagrams and math drawn as crisp vector graphics - rendered entirely on your Mac. MARKSAY AGENT (ONE-TIME PURCHASE) Give Claude Code - or any AI tool that speaks HTTP or MCP - hands on your documents. MarkSay serves a local REST API and MCP endpoint on 127.0.0.1, protected by a bearer token you copy from the app. An assistant can list, read, create, edit, save, and export your open documents, and every change lands in the editor in front of you: watch the preview update, then undo anything with Cmd+Z. Reading is free forever; a 14-day trial unlocks writes so you can try the full loop before buying. PRIVATE BY DESIGN No account. No cloud. Nothing leaves your Mac: the API listens on localhost only, the preview is a locked-down sandbox with page scripting disabled, and MarkSay reads only the folders you have explicitly authorized. WHAT'S FREE The full editor and preview, unlimited manual export, and read access for agents. WHAT THE AGENT UNLOCK ADDS Agent-driven create, edit, save, and export - one purchase, yours for good.
