Chrome Extension · 100% Free

Your tabs,
organized automatically

Tab Economist quietly watches your tabs. When you haven't visited one in a while, it archives it — summarized, categorized, and searchable. Your browser stays clean. Nothing is lost.

No account. No sign-in. Works on Chrome 116+.

Features

Everything your browser
tab bar should do

Built for people who keep too many tabs open and know it. No judgment — just a smarter system.

Auto-Archive
Tabs you haven't visited past your threshold (default 2 hrs) are quietly moved to your Library. You get a 30-second undo notification.
AI Summaries
Gemini Nano (Google's on-device AI built into Chrome) reads each page and writes a one-sentence summary. No cloud, no API key.
Natural Language Search
"That article about M5 chips" actually finds it. Semantic search powered by Nano understands what you mean, not just what you type.
Focus Mode
Pause all archiving during deep work, presentations, or research sprints. Set a timer or end it manually. One click from the header.
Restore with Context
Restore an entire stack of archived tabs and they reopen as a Chrome Tab Group — named and color-coded by category.
Duplicate Detection
Spot duplicate tabs with a visual navigator. Cycle through each group, see exactly what's duplicated, then close extras with one click.
Export Anywhere
Download your entire Library as Markdown or JSON. Your data, your format, your file — no vendor lock-in.
Tab Age Gradient
Active tabs show a color-coded left border — green (fresh), amber (aging), red (nearly idle). No numbers, no clutter, just a visual signal.
Compact Mode
Squeeze the panel to half its height when you need maximum space for your actual work. Toggle instantly from the header.
How it works

Set it up in 60 seconds

No configuration required. It works the moment you install it.

1
Install and open the side panel
Add Tab Economist from the Chrome Web Store. Click the icon in your toolbar — the side panel opens on the right side of your browser. A short 3-screen onboarding explains everything.
2
Browse normally
Tab Economist runs silently in the background. It watches which tabs you visit and when. Sensitive sites (banking, email, medical) are never touched — automatically.
3
Idle tabs are archived with a 30-second undo
When a tab hasn't been visited past your threshold, you'll get a notification with an Undo button. If you don't undo it, the tab is closed and saved to your Library with an AI summary.
4
Find anything in your Library
Switch to the Library tab in the panel. Browse stacks organized by category, filter by chip, or search naturally. Restore any tab in one click — it reopens exactly where you left it.

Your browsing is yours. Full stop.

Tab Economist was designed from day one with a single constraint: no data ever leaves your device.

🔒
Stored locally only
All your tab data, summaries, and settings live in chrome.storage.local — on your device, in your browser.
🚫
No servers, ever
Tab Economist makes zero outbound network requests. There is no backend, no database, no cloud.
🤖
On-device AI
Summaries and search use Gemini Nano — Google's model that runs entirely on your hardware. Your pages are never sent anywhere.
🏦
Sensitive sites excluded
Banking, email, medical portals, and password managers are detected automatically and never tracked, extracted, or archived.
👤
No account required
No email. No sign-in. No user ID. Nothing is ever tied to you personally — because nothing is ever collected.
🗑️
Delete anytime
Clear your Library any time in Settings. Uninstalling the extension removes all data permanently.

FAQ

Common questions

Everything you might want to know before installing.

Will it close tabs I'm still using?

No. A tab is only considered idle after you haven't visited it for longer than your inactivity threshold (default: 2 hours). When that happens, you get a notification with an Undo button — you have 30 seconds to cancel. If you do nothing, the tab is archived.

You can also add any domain to your Protected Domains list in Settings, or use Focus Mode to pause all archiving entirely.

What happens to my archived tabs? Can I get them back?

Archived tabs are saved to your Library with their title, URL, favicon, category, and AI summary. You can restore any tab at any time with a single click — it reopens in your browser. You can also restore entire stacks as a Chrome Tab Group.

Nothing is permanently deleted unless you explicitly delete it from the Library or clear the archive in Settings.

Does the AI actually work? What if I don't have Gemini Nano?

Gemini Nano is built into Chrome 127+ on supported hardware (most modern laptops and desktops). Tab Economist automatically checks if it's available when you install.

If Nano isn't available on your device, the extension falls back to a rules-based categorization system that uses domain patterns — it correctly categorizes sites like GitHub (Work), Reddit (Social), Wikipedia (Research), and so on. Everything else still works perfectly; you just won't get AI-written summaries.

You can check Nano availability in Settings → AI → Gemini Nano.

Which sites does it never touch?

Tab Economist has a built-in blocklist that automatically excludes:

Financial: Banks, payment services, brokerages, crypto exchanges
Email: Gmail, Outlook, ProtonMail, iCloud Mail, and others
Medical: Patient portals and health record systems
Password managers: 1Password, Bitwarden, LastPass, and others
Streaming: Netflix, Hulu, Spotify, and other active media
Local/internal: localhost, 192.168.x.x, and private network addresses
System URLs: chrome://, about:, devtools://, and similar
Sensitive paths: Any URL containing /login, /auth, /checkout, /payment, and similar

You can add your own domains in Settings → Protected Domains.

Does it work with multiple Chrome windows?

Yes. The side panel shows tabs for the window it belongs to, so each window gets its own view. The toolbar badge shows the total idle count across all windows.

Tab archiving runs across all windows — a tab in any window will be archived after it goes idle past your threshold.

How much data does it store? Is there a limit?

The archive is capped at 500 items by default. When the cap is reached, the oldest item is removed to make room for the newest. This keeps storage usage predictable and prevents the extension from slowing your browser over time.

You can export your full archive as JSON before it reaches the cap, then clear it, if you want to keep a longer history.

Does it work in Incognito mode?

Not by default. Chrome extensions are disabled in Incognito unless you manually allow them. If you want Tab Economist to run in Incognito, go to chrome://extensions → Tab Economist → toggle "Allow in Incognito".

Note: even with Incognito access enabled, no browsing data is sent anywhere — Tab Economist still stores everything locally.

How do I uninstall it?

Right-click the Tab Economist icon in your toolbar → Remove from Chrome. All locally stored data (archive, settings, stats) is automatically deleted when the extension is removed. Nothing persists after uninstall.

Is it open source?

Yes. The full source code is available on GitHub under the MIT license. You can inspect exactly what it does, build it yourself, or contribute improvements.
