Grove

Live

A quiet mind map that runs from one offline file. You think, AI organizes.

Grove is a zoomable mind map paired with an editable outline, and it lives entirely in one HTML file. No account, no server, no install. Open it and start typing; close the tab and your maps are still there.

The thing it does differently is capture before organising. Deciding where a thought belongs is the exact friction that stops you writing it down, so thoughts land in a tray at the bottom of the screen and get filed onto branches whenever you feel like it — dragged on a laptop, tapped on a phone. Or you can press one button and let AI propose a grouping, which you edit before anything moves.

That last part matters more than it sounds. Every AI action in Grove produces a preview you approve, never a change it makes for you. Suggestions arrive as dashed ghost buds you keep or dismiss one at a time. And your own words are never reworded — not summarised, not tidied, not improved. That turned out to be the rule everything else had to bend around.

The AI is optional and uses your own Anthropic key, entered in Settings and stored only on your device. Without a key Grove is a perfectly good mind map that makes zero network requests of any kind. No telemetry, no fonts from a CDN, no update checks. It works on a plane.

Free, and free to keep. Download the file and it's yours — there is nothing to cancel and nothing that can be taken away later.

  1. Folder sync, and the limits of browser storage

    Maps living in the browser is fine right up until it isn't. Clear the wrong setting, use a different machine, and they're gone — and "back up your data" is advice nobody follows.

    Chrome and Edge on desktop can now write each map straight into a folder you choose. Point it at a folder inside a cloud drive you already pay for and two machines share the same maps, with no Grove server in the middle and no account anywhere. Safari and most phones can't do this, and Grove says so plainly rather than pretending it worked.

    There's also an auto-backup that drops a dated copy in Downloads when you finish editing, for everyone who doesn't have folder sync.

  2. Proving the API key never leaks

    Your Anthropic key is the one thing in Grove that could genuinely cost you money, and Grove writes a lot of files — exports, backups, .json maps, PNGs.

    So there's now a test that fails the build if the key appears in any of them. Not a code review promise, an actual gate. It felt like overkill until I remembered that the whole pitch is "your thoughts never leave your device," and a key leaking through a backup file would make that a lie.

  3. AI that proposes and never writes

    Three AI actions shipped: Sort my thoughts groups the tray under branches, Go deeper suggests sub-ideas, and Ask me questions plays Socrates and turns your answers into nodes.

    None of them touch the map directly. Sort produces an editable preview where you can rename a proposed branch, move a thought to a different group, or throw the group away. Go deeper produces dashed ghost buds you keep or dismiss individually. Ask me questions only ever adds the words you typed yourself.

    The rule underneath all three: your words are never reworded. When the AI proposes a new branch title it's a suggestion in your vocabulary, and when it files your thought it files it verbatim. Getting that right meant rejecting a few designs that would have been slicker.

  4. Capture first, file later

    Rebuilt the whole map screen around a tray at the bottom. Type a thought, press Enter, it lands in the tray. File it onto a branch now or in a week.

    This came from watching myself not use my own tool. The blocker was never typing — it was that typing required first deciding where the thought went, and by the time I'd decided I'd lost it.

    Also added the outline view, which is the better way to read a map on a phone, and made the Map ⇄ Outline toggle keep your place.

  5. One file, no server, no account

    Started from the constraint instead of the feature list: everything has to fit in a single HTML file you could email to yourself.

    That kills a lot of ideas early, which is the point. No accounts, because there's no server to hold them. No sync, at least not yet, because there's nothing to sync through. No analytics, because there's no way to send them.

    What's left is a mind map that opens instantly and works on a plane.
