AI agents speak markdown
Every LLM reads, writes, and thinks in plain text. Markdown is the native language of AI-assisted thinking — no proprietary format stands between you and your tools.
Open Source — Written in Zig
The editor
of the future.
Not another Obsidian alternative. LazyMD is the text editor for philosophers, product engineers, founders, lawyers, researchers — anyone turning raw thought into structured clarity. Plain text is your alchemy.
Philosophy
Plain text is eating
the world.
In the age of AI agents and LLM-driven development, plain text isn't primitive — it's the most powerful format there is. Every AI tool, every version control system, every OS speaks it natively.
Git-native by default
Every line is diffable. Every change is mergeable. No binary blobs, no sync conflicts. Your notes and code live in the same version control as everything else.
Zero lock-in, infinite portability
.md files work in any editor, on any OS, in any decade. Your content outlives every app. Markdown written in 2004 reads perfectly today — and will in 2044.
Human-readable, machine-parseable
Plain text is the only format that both humans and machines read natively. No schema, no compilation step. Open a file and it just makes sense.
Interfaces
One editor.
Every surface.
Your terminal is just the beginning. LazyMD is designed as a protocol-first editor that can render on any device with a screen.
Terminal (TUI)

Web Editor
Coming soonThe same editing experience in your browser. Real-time collaboration, cloud sync, and zero install. Open a link and start writing.
Native Apps
Coming soonmacOS, Windows, Linux, iOS, Android. Native performance with platform-native feel. One markdown vault, every device in your life.
Any Device
The visionRabbit R1, smart displays, e-ink tablets, embedded systems. If it has a screen and a network connection, LazyMD can run there.
Features
Everything you need,
nothing you don't.
Built for thinkers who live in plain text. Whether you're drafting briefs, shipping products, or writing research — LazyMD stays out of your way.
Vim-Native Editing

Live Preview
Rendered markdown in a side panel. Headers, bold, italic, code blocks with syntax highlighting — all updating as you type.
Multi-Panel Layout

Syntax Highlighting
Built-in highlighting for Zig, Python, JavaScript, TypeScript, Rust, Go, C, C++, Java, and 16+ languages. Theme-aware colors with a pluggable highlighter backend.

MCP Server
Built-in Model Context Protocol server with 22 tools. AI agents like Claude Code and Gemini CLI connect via JSON-RPC 2.0 over stdio.
Brain: Knowledge Graph
Obsidian-style graph view for [[wiki-links]]. Visualize connections between notes with a force-directed ASCII layout. Navigate, explore backlinks, and find orphan notes.
Instant Startup
