The browser remembers tabs.
CleverTabs remembers work.
Transform your browser into a persistent context manager. Organize, search, and restore your sessions instantly, with 100% offline local privacy.
Designed for Tab Overload & Context switching
Stop sacrificing browser performance and your mental fatigue to hundreds of open tabs. CleverTabs brings context boundaries to your browser.
Workspace Isolation
Group your browsing sessions under project-specific workspaces like Work, Research, Personal, or Coding. Switch contexts cleanly in a click.
Groom Sessions Direct
Delete individual tabs from saved cards or append currently open web pages to an existing session instantly. You never have to restore a session just to update it.
Partial Session Restoration
Use the checkbox controls on session tabs to restore only the pages you need, in either the current window or a clean new browser window.
Instant Substring Search
Find sessions, workspaces, or specific pages instantly using a client-side substring index. Filters matching titles, URLs, and tags in less than 300 milliseconds.
Local-First Privacy
No cloud infrastructure, no user accounts, and no tracking. All data is saved on your device inside an IndexedDB datastore. Offline-ready and zero network requests.
Auto Backup scheduler
Configurable background snapshots scheduled via service workers. Purges backups older than 30 days automatically. Restores snapshots with atomic rollbacks.

Your data belongs to you. Period.
Many browser extensions track your history, inject ads, or force you to create cloud accounts to sync your data. CleverTabs runs entirely **on your local machine**.
- No Cloud Backend: Data is saved within your local browser storage.
- No Account Needed: Install and start organizing immediately.
- Zero Network Requests: Offline core architecture translates to 0% tracker risks.
Frequently Asked Questions
Everything you need to know about CleverTabs.
Yes. CleverTabs is free and runs 100% locally. We do not transmit any URLs, page titles, or workspace information to any external server. All configuration and backup snapshots are kept exclusively in your browser's IndexedDB storage.
Absolutely. In the session library cards, you can select any workspace from the dropdown list next to a session. Selecting a different workspace automatically moves the session.
CleverTabs registers a periodic background alarm (using chrome.alarms) inside its Manifest V3 service worker. Every 6 hours, it takes a full snapshot of your workspaces, sessions, and settings, preserving it locally in a backups store. Old snapshots (> 30 days) are automatically deleted.
Yes. You can export your entire IndexedDB state as a formatted JSON file from the settings panel. You can also import this file back into CleverTabs on any machine. The import parser performs Zod validation checks and supports atomic rollbacks in case of insert errors.
Not at all. CleverTabs doesn't run continuous scripts in the background of your tabs. It operates exclusively when you open the popup, perform active session restores, or when a background alarm triggers. Our search engine utilizes indexing algorithms that search 100,000+ urls in less than 300 milliseconds.
