Your tabs, quietly organized for you.
On-device · No accounts · Chromium 116+Tab Economist lives in the side panel. It watches which tabs you actually use, archives the ones you've abandoned, and gives you a searchable, categorized Library you can pull from at any time.
Every 15 minutes, a background sweep checks how long each tab has been untouched. Sensitive sites — banking, email, medical, logins — are skipped entirely.
Idle tabs are moved to your Library with a one-line summary and a category label — Work, Research, Shopping, News and more. You always get a 30-second undo.
Search by keyword, filter by category, snooze for later, restore a whole session with one click — or bulk-delete the dead wood. Your tabs, on your terms.
Built rules-first, so the core features work everywhere. On supported Chrome builds, Gemini Nano silently adds richer on-device summaries — but nothing depends on it.
Tabs you haven't touched in a while are quietly moved to the Library. Configurable thresholds from 30 minutes to 4 hours.
Every tab is categorized by smart domain rules. When available, Gemini Nano adds a one-line summary — fully on-device, no network calls.
Keyword search across titles, URLs and summaries. Category chips let you narrow down to Work, Research, Shopping and more.
Not useful now, useful later? Snooze for 1 hour, tonight, tomorrow morning, or next week. Tabs reopen themselves on time.
Your Library groups by day — Today, Yesterday, This week. Hit Reopen to bring a whole session back as a Chrome Tab Group.
Select mode lets you multi-select with Shift+click, then delete, export, or restore dozens of tabs in a single move.
Press ? to see shortcuts. / to search, arrows to move, Enter to open, Delete to remove, ⌘A to select all.
One click pauses all archiving for a timed window. Great for deep work when you don't want the librarian touching anything.
URL normalization (stripping utm_*, hashes, trailing slashes) means the same article never clutters your Library twice.
Mark any domain as Never archive or Aggressively archive from the Stats tab. Your Library learns your habits over time.
Optionally delete items older than 30, 60 or 90 days. Pruned tabs sit in a 24-hour trash bin so one click can bring them back.
Export your entire Library as clean Markdown or JSON. Your data, your file, zero vendor lock-in.
Tab Economist was built with a single constraint: no data ever leaves your device. No servers, no accounts, no analytics. Ever.
Every tab record, archive item, and setting lives in chrome.storage.local — on your device, in your browser.
Banking, email, medical portals, password managers and login pages are never tracked, scanned, or archived.
No email, no sign-in, no user ID. Nothing is ever tied to you because nothing is ever collected.

Tab Economist is a Chrome and Edge side-panel extension that manages tab overload for you. It quietly watches your tabs, archives the idle ones with a summary and category, and gives you a searchable Library you can pull from later — without ever sending your data anywhere.
Yes — 100% free, no ads, no paid tiers, no upsells. Tab Economist is a passion project. Because it has no backend and no servers, there's nothing to monetize and nothing to subscribe to.
No. Tab Economist is rules-first: every tab is categorized using smart domain rules that work on every Chromium browser. On supported Chrome builds with Gemini Nano available, the extension silently uses it to add a one-line summary to each archived tab — fully on-device. If Nano isn't available, everything still works perfectly.
Banking and financial services, email providers, medical portals, password managers, authentication pages, localhost and private networks, and chrome:// URLs. You can also add your own domains to the Protected Domains list in Settings.
You always get a 30-second undo via a system notification. After that, archived tabs still live in your Library — click any row to reopen the original URL instantly. Nothing is ever lost.
On any active tab row, click the snooze icon and pick a preset: 1 hour, Tonight, Tomorrow morning, or Next week. The tab closes and is tracked in the Snoozed tab. When the time comes, Tab Economist reopens it automatically and posts a gentle notification.
Yes. The Library groups archived tabs by day — Today, Yesterday, This week, Older. Each group has a Reopen button that restores the entire session as a named Chrome Tab Group so you can pick up exactly where you left off.
Plenty. Press ? anywhere in the panel to see the full cheatsheet: / to focus search, arrows to move, Enter to open, Delete to archive, Space to preview, ⌘A / Ctrl+A to select all, Esc to exit bulk mode.
No. There are no analytics, no telemetry, no crash reports, and no outbound network calls. Everything is stored in chrome.storage.local on your device. Read the full Privacy Policy.
Yes — Tab Economist ships on both the Chrome Web Store and the Microsoft Edge Add-ons store. Any Chromium browser on version 116 or later will run it identically.
Free to install. On-device. No accounts, no tracking, no nonsense.
