A brain dump app that sorts it for you
A brain dump works when getting things out of your head takes no effort at all. The catch is the mess it leaves behind. Reteum takes the dump and does the sorting.
What a brain dump is for
Writing down everything on your mind, tasks, worries, ideas, half-thoughts, clears space to think. It helps most when you can do it the moment something occurs to you, in whatever form it comes, without stopping to decide where it goes.
Dump it in seconds
- One box for everything: a typed line, your voice, a photo of a whiteboard, a link, a PDF.
- From a widget, the Lock Screen, Control Center or Siri, without opening the app.
- No folders, tags or titles to choose.
Let Reteum do the sorting
- The Atlas groups what you dumped into subjects on its own and links the thoughts that belong together.
- Search by meaning finds a thought from a few words of it, or a place, a month or a feeling.
- Recall brings up to three older thoughts back each time you open the app. Keep what still matters and clear the rest, so yesterday's dump does not become tomorrow's clutter.
Private by design
A brain dump is unfiltered by nature. Reteum's AI runs on your iPhone, there is no account and no Reteum server, and iCloud sync, if you turn it on, is end-to-end encrypted. Read more about building a second brain without the upkeep.
