A brain dump app lets you get everything out of your head first and decide what it is later. BrainDump opens to a blank page, then helps you sort, find and act on what you wrote.
Same text on a screen. A very different first ten seconds.
| Compare | Brain dump app | Regular notes app |
|---|---|---|
| First thing you see | A blank page, cursor ready | A list, a dashboard or a folder tree |
| Before you can type | Nothing | A title, a folder, sometimes a template |
| Organizing | Later, or never. AI can do it for you | Up front, by you |
| Finding things again | Ask a question, old pages come back | Remember where you filed it |
| Best for | Racing thoughts, ideas, worries, to-dos in one go | Reference docs and wikis |
The whole app is one habit in three steps.


Open BrainDump and type, or talk. Freewrite pages need no title. The widget, Siri and the Mac menu bar get you there in one tap.


Turn a page into a to-do list, an email or a summary. Untangle files a messy folder into named subfolders. Every change waits for your OK.


Ask your notes a question and get the answer with its sources. Nimbo brings back one old page a day, so ideas don't get buried.
