For ADHD brains
For Brains With 17 Tabs Open.
Dumbnote is the offline mind map for ADHD brains. Type every thought as a node — refill the prescription, that song from 2014, the app idea, the rent conversation — then drag the tangle into something you can actually act on. No login wall between you and the idea you just had.
Why this matters
Brain-dump first. Organize when the focus comes back.
ADHD brains don't have a thought-flow problem — they have a thought-capture problem. Seventeen ideas show up at once. By the time the third tool's signup form loads, the first four ideas are gone, the next six have replaced them, and now there's a tab open about a 2014 song you can't remember the name of. The tool was supposed to help.
Dumbnote does the only thing that actually works at the speed of your brain: capture first, structure second. Open the page. Start typing. Every line you press Enter on becomes a node. No login, no workspace setup, no "name your project" modal — just a canvas that catches whatever falls in.
When the focus comes back — three minutes later, three hours later, three days later — the nodes are still there. Drag them into branches. Tag the ones that matter. Park the ones that don't fit yet under a "later" node. The same offline mind mapping tool that captured the chaos is the one that organizes it.

For your work
For when 'just write it down' isn't fast enough.
For brains that finish the next thought before they're done writing the current one, the speed gap matters. Dumbnote uses keyboard-only navigation — Tab to indent, Enter to spawn a sibling, arrow keys to navigate. No mouse, no menus, no "click the + button" lag. You type at the speed you think.
And because it's all offline in a single browser tab, you never lose what you wrote because the auth token expired, the WiFi dropped, or the cloud forgot you exist. The map is on your machine. It's yours.
How it works
How ADHD brains use Dumbnote
-
Open the page
No signup, no onboarding, no "name your workspace" step. The map is there before the impulse fades.
-
Type as fast as the thoughts arrive
Hit Enter for a new node, Tab to nest one under the last. The keyboard does everything — no menus, no clicking, no friction.
-
Dump the whole thought, not just the title
Some thoughts are a single word. Some are a paragraph. Expand any node into a full card and paste the whole thing — paragraph, image, link, half-formed sentence. Nothing gets lost between having and writing down.
-
Park the ones that don't fit yet
Not every thought wants a parent right now. Pull it off the tree as a float node — it sits on the canvas, off to the side, until you know where it belongs. (Or until you decide it doesn't.)
-
Come back when the focus does
The map is still there. Drag the tangle into branches. Tag the urgent ones. Move the "park" ones to a "later" branch. Same canvas, different mode of attention.
Common questions
Questions visitors ask before they try it.
Is this really designed for ADHD, or just marketed that way?
It's designed around the capture-first workflow that ADHD brains gravitate toward. No login, no onboarding screens, keyboard-first navigation, expandable nodes that hold full paragraphs, and float nodes for the thoughts that don't fit anywhere yet. We don't claim it cures executive dysfunction — but it removes the friction between you and the idea you just had.
Why does no-login matter so much?
Because every step between the impulse and the capture is where the thought escapes. Signup forms, email verification, "create your first workspace" — each of those costs you 30 seconds and a thought. Dumbnote is one page. You open it, you type.
Can I dump unstructured thoughts before knowing where they go?
Yes — that's the workflow. Type every thought as its own node. Don't worry about parents, branches, or hierarchy. When the focus returns, drag the tangle into shape. Or use the Graph mode for thoughts that loop back on each other and don't fit a tree.
What if I open it and then forget to come back?
The map auto-saves to your browser. Open the same browser tomorrow, last week, six months later — it's still there. Export to Markdown if you want a copy somewhere else. Nothing expires, no "session timed out" wall.
Does it cost money?
No. Free forever. No premium tier, no per-seat pricing, no "first 100 nodes free." The whole tool, including live brainstorming with a friend, is free.
Is there a way to make the map feel less overwhelming when it's full?
Yes. Use Focus Branch — Shift+click any branch and the rest of the map fades to 35%, so only the part you're working on is at full attention. Or switch to Reader mode for a clean, linear view of the whole thing without the visual sprawl.
