Works the way your memory does.
Reteum is a private notes and journal app for iPhone that takes things in, brings them back, finds them when you ask and shows how they connect. The AI runs on the phone, and your thoughts go no further than your own iCloud, end-to-end encrypted, if you choose.
Your senses take things in all day. Out of nowhere, something you'd forgotten comes back. You wonder what time this afternoon's meeting is, and you look it up. Before you fall asleep, the day runs past once more and the pieces connect.
Reteum was built around those four moments.
Take it all in, like your senses.
Save anything from one box: photos, videos, links and files, or just a line you type or say out loud. A brain dump in seconds, with nothing to file.
- Voice notes and the words in videos become text, in the language you speak.
- Photos and videos keep the time and place they were taken.
- From a widget, the Lock Screen, Control Center or Siri: "Add a thought to Reteum."
Keep what matters. Clear the rest.
Each time you open Reteum, up to three things you saved before come back at the top, the way memories surface on their own. Swipe right to keep one, left to clear it, so notes you no longer need don't pile up.
Drove Highway 1 down to Big Sur. Stopped at every turnout.
Search the way you remember.
Half a memory is enough. A place, a month, a question, or what was in the picture. An AI model on your iPhone searches by meaning, so you don't need the exact words.
- Find photos and videos by what they show.
- The words inside PDFs count, every page of them.
See how it all connects.
The Atlas sorts everything you save into subjects on its own, then links the thoughts that belong together. Open a subject and follow the lines, like going over the day before sleep.
Only you can read it.
Both AI models run on the phone
A private AI app: the text model that searches and sorts, and the image model that sees your photos, work on your iPhone, even in airplane mode.
No account, no server
There is nothing to sign up for and no Reteum server. No analytics, no ads, no tracking. We never see what you save.
Your iCloud, sealed
Turn on iCloud and your thoughts reach your other devices, end-to-end encrypted, so Apple cannot read them either. Or export everything as one zip file. Read the privacy policy.
Free for your first 100 thoughts.
