## What is openote?

openote — Markdown notes with free sync. No account. No subscription.

Other note apps charge a yearly fee just to sync your own devices. openote syncs iPhone, iPad and Mac through your iCloud Drive — free, with no account to create.

Your notes stay plain .md files. Open them in the Files app or any Markdown editor, and take them anywhere. No proprietary format, no lock-in.

WHY OPENOTE

Free iCloud sync
Notes sync through iCloud Drive on your own Apple account. No sign-up, no subscription.

Plain Markdown files
Every note is a standard .md file. Front matter, checklists and [[wiki links]] are kept exactly as you wrote them.

Safe across devices
If a note changes on another device while you're editing, openote keeps both versions instead of silently overwriting one. Your last words are saved even if you switch apps or quit right away.

Mermaid diagrams
Flowcharts, sequence diagrams and more render live from Markdown. Start from a template, pinch to zoom, tap to edit the code. Rendering works offline.

On-device AI
On devices with Apple Intelligence, summarize a note, get tag suggestions, or turn a sentence into a diagram. It runs entirely on your device — nothing is sent to a server.

## Version history (last 5 releases)

### 2.2.0 — 2026-09-29

Your notes, safer.

• Editing on one device no longer overwrites changes made on another — both versions are kept
• Checklists, front matter, [[wiki links]] and nested lists are no longer altered when you edit a note
• Your last few words are saved even if you switch apps or quit right away

Diagrams, fixed.

• Tap a diagram to edit its code — and long-press to view, edit, or delete it
• Pinch-to-zoom viewer for any diagram
• AI-generated diagrams no longer fail to render when labels contain parentheses

Faster
• Search no longer stalls while you type
• iCloud sync only processes what actually changed

Cleaner
• Note previews show your text, not raw markdown or diagram code
• PDF preview returns properly when you cancel sharing
