Notes that think and run.

Znote is 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.

01 · ask

Compose a prompt from your notes.

Type @ and pick what the AI should read — a note, a template, a code block. Type / and pick a prompt — from quick one-shots to live AI sessions. The answer lands inline, in the note you're writing.

a
Summarize a meeting note
@meeting-monday → "give me the decisions and action items."
b
Turn a rough idea into a user story
@user-story-template → "turn this brainstorm into a user story."
c
Cross-check an idea against your research
@user-interviews → "which of these features did people actually ask for?"
d
New — slash prompts & interactive sessions
/brainstorm opens a live chat that becomes a clean note; /rewrite rebuilds a messy one in a single undo-able edit. Every command is a markdown file in your vault — override it, or add your own.

A code block becomes a little tool.

Write a JS / Node block, press play: query a database, call an API, parse a file — the chart or table renders inline. Save the note and you've built a tool. Next week: open, play, done.

a
The Monday sales chart
db.query(...) → barChart(rows). Change the month, press play, done.
b
Clean up a CSV export
Parse it, filter it, render the table — inline, next to your notes about it.
c
Your own tiny status page
await fetch(...) your APIs, print the results. One note, rerun anytime.

const rows = await db.query(`
  SELECT channel, month, SUM(amount)
