Onyx: Local AI Notes

Your private second brain. Talk or type, and Onyx turns it into a beautiful, organized note with headings, checklists and tables, then files it in the right folder. Automatically.

- AI that runs on your device, never on a cloud AI
- Your notes stay on your devices and your own iCloud, never on our servers
- No account, no ads, no subscription
- Made for iPhone Duo, iPhone and iPad

HOW IT WORKS
- Tap the mic and talk, or type a quick note
- Onyx writes it up: a title, headings, bullet points, checklists and tables
- It files the note in the right folder, or makes a new one. No setup.
- Works offline, even in airplane mode: speech to text and AI formatting both happen on your device

EVERYDAY NOTES, DONE FOR YOU
- Meetings: decisions and action items, with a checklist of who does what
- Trips: packing lists and an itinerary by day and time
- Recipes: ingredients and steps, from a quick voice memo
- Journal entries, study notes, to-do lists and ideas

ASK ONYX TO EDIT, BY VOICE OR TEXT
- "Add sunscreen to my Vegas trip list" updates the note you already have
- "Make this a checklist", "Use bullet points", "Make this a table"
- "Fix grammar", "Translate to Spanish", "Make it more formal", "Shorten"
- Preview every change, then Keep or Undo. Version history saves your last 20 versions.

CAPTURE FROM ANYWHERE
- Scan documents, whiteboards and receipts, or add photos
- Import your notes from Apple Notes
- Save to Onyx from the share sheet in any app
- Siri and Shortcuts: "New Onyx note", "Add to Groceries in Onyx"

FIND ANYTHING
Search finds notes by meaning, not only exact words. Ask "what did we decide about the launch?" and Onyx answers from your own notes, with links to them.

BEAUTIFUL ON EVERY SCREEN
- iPhone Duo: unfold for folders and notes side by side with the note open
- iPad: a full split view with keyboard shortcuts
- Light and dark mode, Dynamic Type and VoiceOver
- Swipe to pin, share, move or delete. Deleted notes wait 30 days in Recently Deleted.

PRIVATE BY DESIGN
- Formatting runs on Apple Intelligence on your device
- Your voice is turned into text on device. Audio is never uploaded.
- We never see your notes
- Optional iCloud sync goes to your own private iCloud. Onyx has no servers.
- No account, no ads, no tracking. Data Not Collected.
- Check it yourself in Settings > Privacy & Security > App Privacy Report

FREE, WITH A ONE-TIME PRO
Free: unlimited notes, pictures and scans, AI formatting and filing, Ask Onyx, search, sharing, iCloud sync, and voice notes up to 3 minutes.
Onyx Pro is a single $14.99 purchase, not a subscription: voice notes of any length, your own folders and filing rules, templates, PDF and Markdown export, gemstone themes with matching app icons, and wallpapers. Family Sharing is on.

Good to know: AI formatting needs a device that supports Apple Intelligence (iPhone 15 Pro or newer, or an iPad with an M1 chip or later) with Apple Intelligence turned on. On other devices Onyx saves your notes as written, and everything else works.
