Loved by users
“Worth its weight in gold. Finally got me to switch from Apple Notes when I found this one. You can do so many things with your notes. You can convert them into a business-style report. You can make them into a quiz. Turn them into Flashcards. Interrogate your notes (ask questions and receive answers). Love this!”
“BrainDump has proved to be the most efficient and truly frictionless I have found for my Wordpress blogging workflow. My vision is not great, but I find both the fonts and font size adjustments quite convenient here. And when you finish brainstorming, you can arrange and merge your selected notes into one document.”
“This app is minimal but brilliant. In chaotic world on these days, I am always finding peace, simplicity and calmness and this is what I am looking for, it has no distraction and annoying stimulus, neat UI and functionalities.”
“Finally, a notes app that gets how my brain works. It's simple, fast, and doesn't overwhelm me with features I don't need. I can quickly write down thoughts before they vanish. Highly recommend.”
“Super clean minimalist UI, feels very native, I use Obsidian for study or extensive notes, and Brain dump for well.. brain dumping or temporary notes. This app is great, I love the Mac app even more. The sticky note feature is extremely useful. Syncs super fast.”
“Clean, simple, great functionality and the developer is quite amazing when it comes to updating and listening to users & their suggestions. Never going to use another note app. This is the all in one for me! Thank you for your great work!”
Write first. Let AI shape it later.
The whole app is built around one habit: get it out of your head now, decide what it is later.
Dump it
Open BrainDump and type. No title, no folder, no decisions. The thought is safe before it fades.
Set up one-tap capture with Shortcuts
Turn it into something
Open the AI menu on any dump and get a to-do list, a summary, an email or flashcards. You see it before anything is saved.
Come back and ask
Ask your notes a question and get the answer, with sources underneath. Nimbo brings back one old page a day, so good ideas don't get buried.
Built for your brain
Not for folders and filing systems
Private until you share it
Every note starts private, visible only to you. Share one only when you choose, and decide whether people can view it or edit it.
Everywhere your brain is
iPhone, iPad, Mac, Vision Pro and any browser. Start a thought on one, finish it on another, without thinking about syncing at all.
Untangle any folder
Other notes apps leave the filing to you. Point BrainDump at a messy folder and AI sorts it out: new subfolders, notes in the wrong place and duplicates to merge.
New subfolders, named for you
Related notes get grouped into folders it names for you, or moved into the subfolders you already have.
Notes in the wrong place
That trip note hiding in your Work folder? It spots it and sends it where it belongs, or to a new folder of its own.
Duplicates, merged
Notes that say the same thing become one. The originals go to Trash, just in case.
Nothing moves until you say so. Review every suggestion, rename folders, and take the whole thing back with one Undo.
New
Ask is now a chat that gets things done
Talk to your notes like you'd talk to an assistant. It finds what you need across everything you wrote, then tidies up for you, one confirmed step at a time.

It answers, then shows you where
Ask about a folder or everything. It searches the rest when it needs to and shows the notes it used as cards you can open.

Nothing changes without your OK
Check off items, rename, merge, move, tag or trash notes. Every change shows up as a card with the real notes, and waits for Confirm.

Undo anything, keep going
Changed your mind? Undo puts it back. Follow-ups pick up where you left off, and recent chats stay on your device.
Ask your own notes
Nothing is ever deleted for good: the Trash is as far as it goes.
