A calmer sidebar

Mac 0.1.27 11 Nov 2026

The sidebar and pins are redrawn for both bright and dark boards, folders can have a colour, and a lot of small things work the way you'd expect.

Sidebar and pins

One ground on every board, wide pins that share the width, and a clear mark on the one in front.

Folder colours

Right-click a folder to give it one of the area colours.

Notes

Opening a note without typing no longer counts as an edit, and a note you delete keeps its last words if you undo.

Panels over an answer

Settings, History and the import sheet take clicks and keys while an Explain answer is up.

One question

Marble asks once what you use it for.

Explain, right where you're looking

Mac 0.1.26 8 Nov 2026

Explain now answers on your window as it talks, its 3D models are built in far more detail, and your board has more room.

Explain draws on your window

The answer appears over your whole window as it's told: ink on the page's own words and pictures, notes, charts and 3D models. Press Esc, scroll or click away and it's gone.

More detailed 3D

Models are built from many more real parts, and they can be small or large and stand right on the page.

Explain can look things up

New in this version: when an answer needs facts the model isn't sure of, or current ones, OpenAI's model can search the web as part of answering. It only happens when you ask Marble to explain something.

A calmer board

Cards keep more room between them, and lines between cards that are nearly in line run straight. Areas have a cleaner outline and resize from any corner. The sidebar opens the way you left it.

Signing in, without the wait

Mac 0.1.25 4 Nov 2026

Small things that make signing in for Explain smoother.

Signing in

If an email address can't receive mail, Marble says so at once instead of waiting for a code that never comes. If no code shows up, Marble tells you where to look, and Send again and Use another email stay in reach.

Fixes

See plans no longer brings the Explain pen back over the plans page. The first-run walkthrough is shorter. "How did you find Marble?" shows every site's logo.

Explain how anything works

Mac 0.1.24 4 Nov 2026

Ask how something on a page works, and Marble draws it beside the page. And areas give your board places.

Explain

A drawing of how it works lands beside the page, one you can turn and play. Press ⇧⌘E or Explain in the toolbar and circle part of a page; highlight text, right-click and choose Explain; or right-click anywhere on a page to explain all of it. Your first 10 are free, then Pro or Max. Explain is early, but a lot of fun. Let us know what you think.

Areas, and a proper sidebar

Hold ⌥ and drag on the board to draw a named, coloured area. The sidebar lists your areas first, with their cards inside.

A new look

Warm paper and ink, and a new wordmark.

Cards have weight

A card trails the pointer and settles softly when you let go. Messy mode is back.

No account for Marble

Marble itself needs no account. You only sign in to use Explain.

Fixes

⌘K no longer flashes as you type.

Find any page you've seen

Mac 0.1.23 29 Oct 2026

⌘K finds pages by what they said and by what they're about, in English and Norwegian. It all happens on your Mac.

Search by words and by meaning

Type a few words from a page you visited and it shows up. Type "car" and a page that only says "automobile" shows up too. Settings → Privacy can turn this off and clear what's kept.

A new ⌘K

Pages show as pictures you can click or drag onto the board, and every command and shortcut is in there.

More shortcuts

⇧⌘T reopens a closed page, ⇧⌘C copies the address, ⌘L edits it, ⌘D pins, and many more. Press ⌘E to see them all.

A tidier sidebar

Folds sit first under a folder, then your trails. S folds a card's whole trail into one pile.

Calmer pages

Text opens at the size other browsers show it, an expanded page sits in a quiet frame, and over a photo the frame is the photo, frosted.

One colour for lines, and a readable Light board

Lines and highlights use your space's colour. On the Light board, lines, notes, space dots and sidebar text are now easy to see.

Fixes

⌘⌫ in a text field no longer closes the card, Tab and Esc work as in other browsers, and a board from another profile opens with that profile's logins.

Sign in with passkeys

Mac 0.1.22 27 Oct 2026

Passkeys from Apple Passwords and 1Password now work in your cards, with Touch ID.

One yes from macOS

Turn on Passkeys in Settings → Privacy. That one answer covers Apple Passwords and 1Password, with no extension needed.

A page for each password manager

Settings → Privacy shows what each one does in Marble. 1Password's extension is now an optional extra for filling passwords.

Extension pages open as cards

An extension's welcome or settings page lands on your board, like any other page.

Drag from anywhere on a card

Zoomed out, you can grab a card or a fold anywhere you see it, including its name. It stays under your pointer.

Closing a card shows the whole board

From any zoom, so you're never left looking at empty space.

It updates itself

Mac 0.1.20 26 Oct 2026

Marble checks for updates by itself now.

It checks on its own

Shortly after you open it, and every four hours while it's open. Nothing shows until there's something to install.

Install Now or Later

When an update has downloaded, a bar comes up in the bottom right. Later hides it until you open Marble again.

Still on 0.1.19 or older?

Choose Check for Updates one more time. It's the last time you'll need to.

Bring your tabs

Mac 0.1.19 26 Oct 2026

The first launch takes the tabs you already have open and puts them on a board, still signed in. Then it shows you around.

Your tabs, on a board

Pick a browser and its open tabs land as cards. You stay signed in, and cookie banners get answered on the way in.

A short tour

It has you do each move rather than read about it. Skip what you know. Replay Tour in ⌘K runs it again.

Read Mode

This used to be Expand Page. Tab or Esc now goes straight back to the board.

A card's name sits on the card

Hover a card and its name shows in the middle of it, so you aren't looking in two places. It turns dark on a dark page.

Full screen

The green button works now. The board gets its own Space.

The sidebar lines up

Pins, favicons and the traffic lights share one column.

1Password, without the workaround

The fix is in Marble's copy of Chromium now, so sign-in works the way it does in Chrome.

A smaller download

242 MB, down from 307. The icon got a cream tile too, so it doesn't look lost in the Dock.

A photo behind the board

Mac 0.1.18 15 Oct 2026

Each space can hold a picture. Trail lines run straight and turn at the corners. 1Password fills a card.

A photo behind each space

Choose image from the space menu. The picture stays with the screen, shifts a little as you move, and blurs as you go in to read.

A large photo stays out of the way

It loads off to the side, so the board doesn't freeze. Phone photos come in upright, and a bigger window gets a sharper copy.

Cards fade into the picture

Glass sits over the photo. A faded card sinks into it, and reading one fades the rest of the board.

Trail lines run straight and turn

A line is a straight run with a rounded corner. Change sides and the whole route swings over.

A line docks on any side

Left or right, and the top or bottom while cards overlap. The dot walks around the card as the side changes. The line you drag is the line that stays.

Light stays solid on a photo

Light is the cool grey twin of Charcoal. Pills and the sidebar stay solid when a photo is behind them.

Arrow keys step between cards

The card you land on gets the hover look. Enter opens it. Esc, or the pointer, lets go. S folds that branch, and unfolds a pile.

A pinch keeps going

Put a card down with a pinch and the same gesture zooms the board.

1Password fills a card

Set it up from Settings, under Privacy. Add it from the Chrome Web Store, allow Marble in 1Password, and it fills and signs in from a card.

The other managers are listed

Bitwarden, Proton Pass, and Dashlane show up there. They are not connected yet.

A new board opens on Charcoal

A new install, and every new space, starts on the same dark board.

History stays with the profile

Each profile keeps its own history and its own cookies. Delete Browsing Data clears that profile, by time or all at once.

Restart installs the new version

Mac 0.1.17 28 Sep 2026

A Restart replaces this copy, including one that macOS had opened read-only.

Only your downloads stay marked

Marble had been marking its own files as downloaded from the internet, including the copy Restart installed. macOS opened that copy read-only, so the next Restart had nowhere to write.

A locked copy unlocks itself

The first time that copy opens, it unlocks.

An old version says so

If a Restart ever opens the old version, Marble says so, points you to marble.surf, and stops offering that Restart.

It proves the update before it ships

Each release updates itself twice from a locked copy before it ships.

Still on 0.1.14

Download Marble from marble.surf, drag it into Applications, and choose Replace.

Restart was opening the same version

Mac 0.1.16 28 Sep 2026

Opening Marble from the disk image left the Applications copy locked, so Restart could not install what it had downloaded.

The Applications copy was locked

Check for Updates could download, and Restart could not install it. The card came back.

This disk image replaces that copy

Quit Marble and open this disk image. After that, Restart can install again.

Restart could lock the copy it installed

0.1.17 fixes that.

Fold a trail

Mac 0.1.15 28 Sep 2026

A trail can fold into a pile. Light is a warm board, and the sidebar is darker than the board.

Fold one trail

Right-click a trail and fold it. The pile gets a +N. Click that to look inside, and name it while you're there.

The hidden cards come along

Drag the pile and the cards you can't see come with it.

Lines grab an edge

Lines between cards grab the left or the right edge.

The right-click menu has its own icons

The little … was doing too many jobs.

A pin inside a fold opens the page

It opens the page, and it no longer draws a box around itself.

A few things stopped twitching

A menu or ⌘K no longer grows the card under the cursor. Names under a fold stay readable, and sidebar labels stay put while a page loads.

Light is a warm board

The sidebar is darker than the board, which is the right way around.

Bring Chrome onto the board

Mac 0.1.14 23 Sep 2026

A Chrome profile's open tabs land on a new board, signed in, on a Marble profile of their own.

Import a Chrome profile

Nothing is written until you confirm the name and color.

Profiles stay separate

Boards and sign-ins stay apart. Switch, create, edit, or delete them from the command palette.

Settings and the shortcut sheet

Settings is ⌘,. The shortcut sheet is ⌘E.

Some cookies stay behind

A site's cookies are imported only when every one of them can be stored. Google, Gmail, and YouTube are left out for now, so those tabs open and you sign in here. Saved passwords are not imported.

Marble is out
