AI notes for iPhone
The notes app that answers back.
Capture any thought the way you’d text a friend — words, voice, photos. Weeks later, ask in plain language and get the answer, not a search box.
Free to start. No card, no setup.
Parked on level 3, near elevator B
Saved.
Where did I park?
Level 3, near elevator B — you told me on March 3.
Capture
As fast as texting yourself
No folders to choose, no titles to invent, no blank page. Open the app, type it or say it, done. Voice notes stay voice notes — transcription happens in the background. Photos get captions automatically.
- Text, voice, and photos in one chat
- Categories are inferred — the app never asks you to file anything
- Works exactly like the messaging apps you already know
Ask
Ask your memory anything
“Which wine did we like in Vienna?” “What’s my locker code at the gym?” “When did I last change the air filter?” Second Brain answers from your own notes — and shows which ones it used.
Lists & agenda
Say it once. It’s on the list.
“Add sunscreen to the packing list” — added. “Remind me Thursday at 9 to call the dentist” — scheduled. Lists and a calm agenda build themselves out of what you say.
Privacy
How your memories are handled
- Your notes are isolated to your account — strictly per user, enforced in the database.
- AI processing is opt-in: the app asks for your explicit consent before your first note is processed.
- Your notes are never used to train AI models.
- Delete everything, any time. Deletion is immediate and complete.
- Our AI sub-processors are named in plain language in the privacy policy.
