Features

NextNotePad packs a full desktop-class editing experience into a single browser tab. Every capability below works offline once loaded.

Monaco editor

The same engine that powers VS Code — 80+ languages, IntelliSense, multi-cursor.

Open many files at once, split the workspace vertically or horizontally.

Folders, drag-and-drop, quick open, and support for 100k+ files.

Install once, work anywhere. Files persist in IndexedDB across sessions.

Opt into Drive sync to keep files across devices with your Google account.

Fast search, regex, case-sensitive, and cross-file find & replace.

Side-by-side diff for files or pasted snippets.

One-click prettify/minify for JSON, HTML, CSS, JS, and SQL.

REST client, base64, JWT decode, hashes, UUIDs — built in.

Dark, light, and system themes with JetBrains Mono at any size.

Familiar shortcuts — Ctrl+S, Ctrl+F, Ctrl+Z — that stay out of your way.

No telemetry. Files stay on your device unless you enable sync.
