Everything it does. On one page.

Save a tab, a window or a selection. Rename, reorder, drag and drop, sort, open all or just the ones you pick.

Keep work, side projects and that trip apart — a sidebar on the board, a switcher in the side panel.

No caps on collections, saved tabs, spaces or notes. Pro adds power, never room.

Cards, List, Launcher and Wide. Pro adds a Table, a free-form dashboard and a mind map.

Notes and checklists right on the board, image cards, PDFs dropped on a collection.

Press Space on a saved tab to preview it without opening a tab.

Right-click a page, a window or a link → Save to collection. One click in the toolbar for the current page.

Turn browser bookmark folders into collections in one go, with one Undo.

Collection covers, 3D, tile and duotone icons, note styles and Home backgrounds.

Idle tabs free their memory and stay in the tab strip; they reload on click. Exceptions per site.

Tabs you stopped using move to the archive on their own. Time away from your computer doesn’t count.

One click, or automatically. Smart about tracking parameters and fragments.

Open a page you already have and the existing tab comes to you instead.

All windows, or the ones you pick, into the one you’re in.

Every open tab on one screen: filter by site, age or duplicates, then close, save or group them together.

Close tabs by address or title pattern with a live preview of what goes.

Pin every tab in a window — or unpin them all — in one undoable step.

Every tab group is mirrored, so a group closed by hand or by a restart comes back whole.

Reload a tab every 30 seconds up to every hour.

Every saved page in one place, with Forgotten to resurface what you saved and never opened.

Read saved copies in a clean Text view or the original Page view.

Keep a readable copy of each page you save, so it outlives the site. Copies already taken stay readable for everyone.

Highlight passages in saved copies — and with Pro, add notes to them.

Full-text search through the words of every saved copy, not just titles.

An exact MHTML or PDF snapshot of a page, shown sandboxed. Chromium browsers.

Find the same page saved in several collections.

Check which saved pages are gone or moved, and update their addresses.

Remind me ▸ on a saved tab or a note, and it comes back when you said.

Headings, lists, callouts, toggles, tables and [[links]] between notes.

Open notes in the side panel and write while you browse.

A “why did I save this?” line and tags on any collection or saved tab.

Kanban boards with plain cards inside a note. Pro adds due dates, labels, checklists and full-page boards.

Live collection and query blocks, templates and the daily note.

Search and replace across all your notes at once.

Sketch right in a note with /drawing — works offline.

Every note, as plain Markdown files, whenever you want them.

The palette over the page you’re on, with ⌥⇧K — no need to switch tabs.

Include your browser’s bookmarks and history in search, if you allow it.

The board filter matches notes and tags, with tag chips to narrow down.

Shortcuts for saving a window, closing duplicates and more — changeable in the browser.

Block distracting sites for a set time, with a calm block page instead of an error.

Need in anyway? Unlock for a few minutes after a short wait or a typed phrase — enough to break the reflex.

Recurring focus hours and daily per-site time budgets.

Work and break cycles, and blocks that can’t be turned off until they end.

Every closed tab lands here, grouped by day, searchable and restorable.

Every automatic close, move or merge can be undone.

Automatic snapshots of all your windows, restored exactly — a quiet safety net.

A full copy in your Downloads folder on a schedule, with a visible health status.

Toby, OneTab, Session Buddy, Workona, Pocket, bookmarks and more — with folders, notes and dates.

Everything as JSON and HTML bookmarks; any collection as Markdown too.

Collections, notes, images, highlights and reminders between your computers.

New browsers are approved from one you already have, with a matching code. A recovery key for the worst case.
