Quarto

Smart, private tab grouping, reminders, and contextual notes — fully on-device.

Quarto brings order to a noisy tab strip without sending anything about your browsing anywhere. It clusters related tabs, suggests where new ones belong, holds time-based reminders that fire even after a tab is closed, and keeps a short note per URL so the context you built up does not evaporate next time. Suggestions are suggestions. Nothing is ever auto-applied without an explicit click. WHAT IT DOES - Smart group suggestions. Domain bucketing plus a token-similarity pass surfaces ideas like "5 tabs from github.com, group them?" without thrashing your workflow. - Add-to-existing-group hints. Open a new tab and Quarto scores it against your live groups. A confident match becomes a one-click prompt. - Tab reminders. Pick 1h, 3h, Tomorrow, or Next week. The reminder fires even if you closed the tab, and reopens it on click. - Per-URL notes. Short Markdown-friendly notes keyed by a normalized URL. Pin the ones you want to keep at the top. - Three surfaces. Side panel, popup, and options share one clean, keyboard-friendly design system. Light and dark follow your system setting. PRIVACY BY DESIGN - No remote APIs. All clustering and scoring runs locally in the service worker. No model server, no analytics, no telemetry. - No content scripts on your pages. Quarto only reads the tab metadata Chrome already exposes (URL, title, group id, color). - No cross-device sync. Storage stays in chrome.storage.local. - One optional outbound request. Website icons are fetched from Google's public favicon service. They are decorative; block that domain and nothing else breaks. - Export, import, or clear all your data from the Options page at any time. Requires Chrome 116 or newer.
