Truly Offline
No cloud. No login. Just download the HTML file and open it in your browser. Your ideas stay private.
The offline mind map for studying, writing, researching, and sorting the tangle in your head. One HTML file. No login. Works forever.
Some people open it the night before a literature review is due. Some open it at 35,000 feet to plot chapter twelve. Some open it because there are seventeen thoughts in their head and none of them will sit still long enough to become a sentence. Dumbnote Mindmap is a single page that loads once and works forever — offline, account-free, the same shape on a school Chromebook as on a research workstation.
One tool. One HTML file. Yours forever.
No cloud. No login. Just download the HTML file and open it in your browser. Your ideas stay private.
No subscriptions. No vendor lock-in. One HTML file that works today and will work in 10 years.
Take your work anywhere. Export to clean Markdown that flows straight into Google Docs, Obsidian, or any editor.
Tab, Enter, arrow keys, hotkeys for tags. Mindmap as fast as you can think — no mouse fatigue.

Mindmap mode
Hierarchical mindmapping that's faster than your mouse. Tab, Enter, and arrow keys are all you need — but when your hand reaches for the cursor, the map answers back.
Pick up any node and drop it on a different parent. The connector re-routes mid-drag — the child re-parents as soon as you let go.
Click any branch and the rest of the map fades to a quiet background — the branch you're working on outstands. Click empty space to bring everyone back.
Click a node, pick a tag (or two), pick a color. Tags appear above the node like sticky labels; color recasts the whole branch's stroke at once.
Graph mode
Open a Graph document for ideas that don't fit in a tree — nodes anywhere, connections in any direction, shapes that mean what you mean. Like Obsidian's graph view, but offline and free.
Rich content nodes
Sometimes it's a paragraph, an image, an idea that needs room to breathe. Expand any node into a full card with rich text, images, and Read-more. For ADHD brains: dump the whole thought, not just the title.
Offline collaboration
Real-time collaborative mindmapping over end-to-end encrypted peer-to-peer connections. No account to create, no platform that owns your draft. Works after the first handshake, even when the WiFi doesn't.
Reader mode
When the mapping is done, switch to Reader Mode and your mindmap becomes a clean, distraction-free article — the same content, rendered for focus. Built for students reviewing for exams without the visual chaos.
More tools
The mindmap toolkit goes deeper than the headline modes — these are the small, sharp tools that change how you think.
Shift+click any branch and the rest of the map fades to 35%. Read the part you care about without losing the room.
Tag any node, then filter the whole map to just the tags that matter. Press 1–9 as hotkeys.
Right-click any branch and its children collapse into dots. Click each dot to reveal — like flashcards on your map.
Pull a thought off the tree and stick it anywhere on the canvas. For ideas that don’t fit the hierarchy yet.

Feature parity
Mind-mapping tools usually trade off a few axes — free or offline, rich-text or graph, collaboration or privacy. Dumbnote refuses the trade-off.

FAQ
Everything you need to know before you open a single mind map. No fine print, no upsell.
Dumbnote Mindmap is a single HTML file with all code embedded. Once downloaded, it runs entirely in your browser without any server connection. Your data is stored in browser IndexedDB, staying completely private on your device.
Any modern browser works: Chrome, Firefox, Safari, Edge, and Brave. The app uses standard web technologies that have been supported for years, ensuring compatibility.
Your mindmap auto-saves to browser IndexedDB as you work. To create backups or share, use the Export feature to save as Markdown or SVG files.
There's no hard limit, but browser IndexedDB typically allows much more storage than localStorage. That's enough for thousands of nodes with descriptions. For very large maps, regular exports are recommended.
Node types come with predefined colors to help you organize your thoughts visually.
Yes. Dumbnote Mindmap is designed for thought-dumping first, structuring second. You can spawn nodes as fast as you can type, then drag them into hierarchies later. There’s no login wall, no onboarding flow, and no setup — so the idea you just had doesn’t escape while a sign-up form loads.
Dumbnote Mindmap runs from a single HTML file in any browser — including school-issued Chromebooks and locked-down library machines. No account needed, no internet required after the first load, and it exports to Markdown so your essay outline travels with you into Google Docs or Word.
Yes — and offline matters here. Researchers working with unpublished findings, interview transcripts, or sensitive sources can map sources, themes, and arguments in Dumbnote without anything syncing to a third party. The Graph view also reveals citation clusters your linear notes miss.
Fiction writers map plot beats and character relationships as branching hierarchies; nonfiction writers map argument structure before drafting. Dumbnote supports both — hierarchical Mindmap for outlines, freeform Graph for character webs — and works fully offline, so you can plot on a plane.
No. Ever. There’s no signup, no email, no free trial. You open the page, you start mapping. Your data lives in your browser. Optional cloud sync is available if you want it, but the default is local-only and always will be.
A brain dump captures; a mind map organizes. Dumbnote is both. Start by typing every thought as a node — that’s the dump. Then drag, group, and connect them into branches — that’s the map. Useful for ADHD brains, overthinkers, and anyone who needs to externalize before they can sort.
