A Chrome extension, bound in quarto

Tabs you can think with.

Quarto folds a noisy tab strip into labeled groups, quiet reminders, and a note for every page. All of it on your machine. None of it without your click.

The chapters

Four leaves. No magic.

Quarto reads only the tab metadata Chrome already exposes, sorts it with small local heuristics, and waits for you to decide. Each capability is one leaf of the fold.

Leaf I · Gather

Loose tabs, gathered.

Quarto clusters related tabs with domain bucketing and a token-similarity pass, then asks. “5 tabs from github.com, group them?” It surfaces the idea without thrashing your strip every time you open a tab.

  • Ranked by a confidence score you can see.
  • Suggestions are suggestions. Nothing applies until you click.

Leaf II · File

New tabs find their place.

Open a new tab and Quarto scores it against your live groups. A confident match becomes a single, calm prompt. A weak one stays quiet.

  • One click to file it, one to dismiss.
  • The threshold lives in Options. Tune it to taste.

Leaf III · Return

Reminders that outlive the tab.

Pick 1h, 3h, Tomorrow, or Next week. The reminder fires at the chosen time even if you closed the tab, and reopens it on click. The snooze always shows the resolved fire time, so you know exactly when it returns.

  • Backed by Chrome alarms, so idle browsers still fire.
  • Custom durations, with your last choice remembered.

Leaf IV · Recall

A note that remembers why.

“Why did I open this? Where did I stop?” Keep a short Markdown note keyed to a normalized URL, so the context you built up does not evaporate next visit. Pin the ones worth keeping.

  • Normalized URLs, so the note follows the page, not the query string.
  • Stored locally. Never indexed, never sent.
Also bound in
  • ⌘K command palette across every tab
  • Editable snooze presets
  • Light and dark, following your system
  • One-click JSON export

The endpaper

Privacy is not a setting. It is the architecture.

The cheapest way to keep your browsing private is to never collect it. Quarto has no backend to send anything to. The clustering that feels smart runs in the extension's own service worker, on your machine, and stops there.

Where your data liveson your device
  • No content scripts on your pages
    Quarto reads only the tab metadata Chrome already exposes: URL, title, group id, color. It never touches page content.
  • No account, no mirror
    Storage stays in chrome.storage.local and is never copied across devices. There is nothing to log into and nothing to leak.
  • One optional outbound request, documented
    Site icons load from Google's public favicon service. They are decorative. Block that domain and nothing else breaks.
  • Your data, your call
    Export everything to JSON, re-import it, or wipe it permanently from the Options page at any time.

Three reaches

One system, wherever you reach for it.

Side panel, popup, and options share one keyboard-friendly design language. Light and dark follow your system by default.

Side panel

The home base. Suggestions, groups, the current note, and waiting reminders, docked beside the page.

Popup

Quick capture from the toolbar. Jot a note, set a reminder, and get back to work.

Options

The full settings room. Thresholds, snooze presets, theme, and one button to export or wipe everything.

Questions

The things worth asking.

No. Quarto has no backend, no analytics, and no telemetry. Your notes, reminders, and settings live in chrome.storage.local on your machine. The only outbound request is to Google's public favicon service to draw site icons, and it carries nothing but the domain. Block it and every other feature still works.

Yes. Grouping, scoring, notes, and reminders all run locally, so they work with no connection at all. The only thing that needs the network is fetching site icons, and those are purely decorative.

Never without you. Suggestions are suggestions. Quarto surfaces an idea and waits. A group is created, a tab is filed, or a reminder is set only after an explicit click. You can dismiss anything, and it will not nag.

Only what the features require. tabs and tabGroups read tab URLs, titles, and group membership to cluster them. alarms fire reminders on time. notifications show them. storage saves your data locally. sidePanel renders the main surface. Host access lets tab reading work on any site you have open. It reads Chrome-exposed metadata only; it does not inject scripts or read page content.

Bring order to the noise. Quietly.

Add Quarto and let the tab strip become something you can think with. It runs on your machine, and it waits for your click.
