What is PulMap?
PulMap is a lightweight web application for capturing, structuring, and refining your ideas as a hierarchical mind map. It is designed for writers, students, planners, engineers, and anyone who thinks better when their thoughts are laid out visually. Unlike most mind-mapping services, PulMap does not require an account, does not upload your data to a server, and does not lock you into a proprietary cloud. The entire experience is local-first: maps are created, edited, autosaved, and reopened on your own machine, even when you have no internet connection.
Why offline-first?
Most modern productivity tools assume a stable network and a centralised account. That assumption breaks down on planes, in subways, in classrooms with restricted Wi-Fi, and in any environment where privacy matters. PulMap was built with the opposite assumption: the network is optional. After the first page load, the app is fully cached as a Progressive Web App. You can keep building maps offline; nothing leaves your device unless you explicitly choose to share. This makes PulMap a quiet, dependable thinking tool rather than another service that holds your work hostage.
Key features
- Local-only storage. Maps are persisted in your browser's storage. Nothing is sent to a remote database.
- Multiple maps in tabs. Open several mind maps side-by-side and switch between them like browser tabs.
- Keyboard-first editing. Add siblings, indent children, navigate, undo, and redo without ever leaving the keyboard.
- Autosave with full history. Every change is recorded; step back and forth through the history without losing work.
- Image export. Save any map as a PNG suitable for documents, slides, or quick sharing.
- Link-based sharing. Encode an entire map into a shareable URL; the recipient opens it locally without any account.
- Dark mode and themes. Switch between light and dark themes with system preference detection.
- Ten languages. Korean, English, Japanese, Chinese, Spanish, Arabic (with RTL layout), Russian, Portuguese, French, and German.
How to use PulMap
- Open pulmap.app in any modern browser. No installation or sign-up is required.
- Use the + button at the top of the screen to open a new tab; each tab holds an independent mind map.
- Open the hamburger menu (☰) on the top-left to browse, rename, pin, or delete previously saved maps.
- Type into the central node to set the topic, then press the keyboard shortcut for "add child" or "add sibling" to grow the tree.
- When finished, copy the share link, export as an image, or simply close the tab — the map is autosaved and will be there next time.
Privacy and data ownership
PulMap follows a strict local-first principle. Mind map content is stored in your browser using local storage and IndexedDB, which means it is bound to the device and the browser profile you are using. There is no PulMap account system, no server-side database of your maps, and no analytics that profile what you write. Anonymous usage statistics may be collected through Google Analytics only if you grant consent through the cookie banner, and even those signals do not contain map content. If you want to move your work to another device, the share-link export gives you a portable, plain-text representation that you fully control.
Who is PulMap for?
Writers planning a chapter, students reviewing for an exam, engineers sketching system designs, product managers preparing roadmaps, teachers building lesson plans, and anyone who has ever wished a sticky-note wall fitted in a browser tab. PulMap is intentionally minimal — there are no checklists, no kanban boards, and no calendars. It does one thing: turn the structure of your thinking into a map you can actually look at.
