MEditor — Native macOS Markdown Editor with AI Agent

Everything you need

Built for writers who
think in Markdown.

Every feature — from live preview to workspace tools — is designed to stay out of your way and let you focus on writing.

Built-in AI Agent

Multi-turn reasoning loop. The Agent reads your document, calls tools, sees results, and keeps going until the task is done — all inline.

Real-time Preview

Editor and preview scroll in sync. Code blocks, Mermaid diagrams, and math rendered instantly as you type.

Rendered Markdown preview with tables and lists

Workspace Tools

List files, search across your vault, open tabs, run sandboxed shell commands — all accessible to the AI Agent.

Workspace sidebar with file list and document outline

Streaming Output

Responses appear word-by-word. Tool steps show inline with expand/collapse detail — you always know what the Agent is doing.

Bring Your Own Key

9 provider presets out of the box — OpenAI, Anthropic, DeepSeek, Kimi, GLM, Qwen, OpenRouter, Groq, Ollama — plus a local Claude CLI fallback. Any OpenAI-compatible endpoint works.

Export & Beautify

Export to HTML, PDF, or 2× PNG in one click — themed PDFs with clickable links, and a pre-flight check that catches dead links and missing images first.

Slash Commands

Type / anywhere — /polish, /outline, /translate, /table. Commands that rewrite your document stream a diff you confirm before it lands.

Local History

Every save keeps a snapshot, no setup required. Diff any two versions and restore in one click — the restore itself is undoable.

Images Auto-save

Paste a screenshot or drag an image in — it's written to assets/ and inserted as a clean relative path. No more broken image links.

LAN Sharing

Built-in HTTP server with one-time token auth. Share your document over Wi-Fi instantly.

AI Agent

Your AI writes, refactors, and edits — with real tool calls.

MEditor ships with a full AI Agent, not just a chat panel. It reads your document, calls tools to patch specific sections, searches your workspace — and shows every step transparently.

Multi-turn reasoning loop that runs to completion
Document tools: read, write, patch, insert with precision
Workspace-confined writes & risk-graded shell commands — every risky action needs your approval
Visual Diff Review for AI-proposed changes before you accept
Slash commands & a selection floating bar — rewrite, tighten, expand, translate without leaving the editor
Current document auto-attaches as context, smartly trimmed around your cursor when budgets get tight
Diagnostics with one-click "Let Agent fix it" — the model repairs, then re-scans so you can compare
OpenAI & Anthropic SSE streaming, plus Claude CLI backend
Skill system — built-in + an extensible gallery

Editor

A real editor. Not an afterthought.

Syntax highlighting for 40+ languages, bidirectional scroll sync with anti-loop protection, native find & replace with jump-to-line, and a fuzzy file finder (⌘P) — everything you'd expect from a desktop app.

Live Markdown preview with Mermaid diagram support
Presentation mode — turn any document into slides
Focus mode for distraction-free writing
Global search across the workspace (⌘⇧F)
Copy as rich text (⌥⌘C) — paste into email or Feishu with formatting intact
Todo inbox with calendar & week timeline views
Document templates for recurring note types
Tabs: drag to reorder, reopen closed, right-click for close-others / reveal in Finder / save as template
GitHub, Nord, and Dracula themes
Automatic updates — new versions install themselves
