ADHD brain dump
A Brain Dump That Doesn't Make You Sign Up First.
Your working memory is bad at being a hard drive. Especially when seventeen thoughts arrive at once and the only tool you have asks you to name a workspace first. Dumbnote is the brain-dump surface for brains that work differently — open the page, type, done.
Why this matters
The thought escapes while you're opening the app.
ADDitude calls it "interior hyperactivity" — that racing-mind moment when your thoughts won't slow down. CHADD's adult-ADHD guidance is just as direct about the fix.
One of the best ways to stop ruminating is to externalize your thoughts — get them out of your brain.
— CHADD, "From Chaos to Clarity"
The problem is the gap between *thought occurring* and *thought captured*. Every step in that gap is a place the thought escapes.
Why most tools fail at the capture moment
Most note tools assume you'd set them up once — pick a template, name a workspace, configure folders — and then capture quickly. That assumption breaks for ADHD brains.
Dumbnote inverts the assumption. Zero setup, no signup, no template selection. Open the page, press Enter for a new node, Tab to indent. The thought lands on the canvas before your hand reaches the mouse. It's the offline mind mapping approach to brain-dumping: capture first, structure second, file never.

For your work
For Brains That Catch Ideas Faster Than They Can Write Them.
My ideas lived in one world, my tasks lived in another, and my brain had to be the integration layer.
— Indie Hackers founder, paraphrased
The brain-as-integration-layer problem is the real cost. Every time your mind has to remember "I had an idea about X, and it relates to Y, and I need to do Z about it" — without externalizing — that's working memory you can't use for the actual work.
Float nodes are the unlock
Drop a thought on the canvas without committing to where it belongs. Not under a project, not in a folder, not tagged — just floating.
The "I had a weird idea about the API design at 3 a.m." idea can sit on the canvas for three days until you decide it belongs under the platform work. Or you realize it was nonsense and delete it. Either way, your working memory let it go.
How it works
The capture loop, in three keystrokes
-
Open the page
One tab. dumbnote.app/mindmap/. No signup screen, no welcome modal, no "name your first workspace" friction. The canvas is there before your second sip of coffee.
-
Press Enter to add a thought, Tab to nest under it
Enter spawns a new node at the same level. Tab indents the new node under the previous one. That's the whole keyboard contract — type, Enter, Tab, type, Enter, Enter. The keyboard never leaves the home row.
-
Don't organize yet
Resist the pull to structure. The dump comes first — every thought, every fragment, every "I should remember to ask Maya about that thing." Structure is a separate cognitive task; doing both at once is what kills the dump.
-
When a thought needs more than a label, expand the node
Some thoughts are a word ("dentist"). Some are a paragraph ("the reason the staging env is broken is because I changed the rollback script last Thursday and didn't test the path where..."). Expand any node into a rich card and paste the whole thought — title plus paragraph plus image if needed. Nothing lost.
-
Come back when the focus comes back
The map auto-saves. Close the tab, lose the WiFi, restart the computer — the dump is there tomorrow. When focus returns (3 minutes, 3 hours, 3 days), drag the float nodes into branches. Tag the urgent ones. Park the unclear ones in a "later" bucket. Same canvas, different mode of attention.
Common questions
Questions visitors ask before they try it.
How is this different from a notes app?
Apple Notes and similar tools assume your thoughts live in one document, in a linear order, with a folder structure. Brain dumps don't. Brain dumps are non-linear, non-hierarchical, and unfinished by design. A mind-map canvas matches that shape — nodes can sit anywhere, in any order, without a parent, and you can decide later (or never) where they belong.
Will I have to organize everything I dump?
No. Many users never organize most of what they dump — and that's fine. The dump is the value. The act of getting it out of your head is what frees up the working memory. If half the nodes never get a home, that's honest information about which half mattered.
Does it work offline?
Yes. The whole tool is a single HTML file in your browser. After the first load, no internet needed. Brain-dump on a flight, in a tunnel, during the WiFi outage — the canvas keeps working.
What if I forget to come back?
The map auto-saves to your browser. It's still there when you remember. Some users come back days or weeks later and find half the thoughts have either resolved themselves (no longer needed) or revealed a pattern (oh, I've been thinking about this thing five times — I should actually do something about it).
Is it really free?
Free forever. No premium tier, no per-seat pricing, no "first 100 nodes free." The whole tool is the same one anyone else uses.
Can I export my brain dump somewhere?
Yes — Markdown, SVG, PNG, or Mermaid diagram. Markdown is the most portable; drops cleanly into any document or note app.
