I build Znote.

A clean, local Markdown editor with two things built in: AI that answers from your own files, and code blocks that actually run. Everything else stays out of your way.

Znote — typing @ to hand the AI a note, with the answer landing inline

Type @ to hand the AI your own notes — the answer lands inline, in the file you're writing.

Why I build it

Get the idea out. Shape it. Ship it anywhere.

I build Znote for that one loop: a thought comes out of my head, takes shape against my own files, tools and data, then leaves ready to run in whatever stack I'm in.

The notes stay yours

Plain .md files in a folder you choose. No account, no cloud, no telemetry by default. An Obsidian vault opens as-is — and if Znote disappeared tomorrow, every note would still open in any editor.

A note you can run

Write a js block and press play: query a database, call an API, parse a CSV. The chart or table renders inline. Save the note and you've built a small tool — open it next Monday, press play, done.

The AI lives in the note

Type @ to hand the model your own files, / to pick a prompt. No chat window, no copy-paste. Through MCP it can act too — GitHub, Postgres, Slack, Linear — with the result saved in the note.

Znote started as NotebookJS, a small JavaScript playground. That playground is now the code block inside Znote.

And the rest?

Just Markdown.

A calm WYSIWYG editor for plain .md files on your disk. Built with Electron and React, shipping monthly, by one indie dev.

The best “Jupyter-like” notebooks for JS.

My go-to JavaScript playground. Run code directly in the app — huge time-saver. Clean interface, easy to navigate.

Incredible product. Lets users learn and prototype faster. The AI integration is fantastic and JS+Markdown support is top-notch.

The deal

Free to use. Bring your own key.

Every feature, no license, no subscription. The AI runs on your own key — OpenAI, OpenRouter, or 100% local with Ollama — so you pay your provider at cost, or nothing at all.
