Your lens on every tab.
TabLens bundles five tab quality-of-life tools behind simple toggles — a usage timer, scroll memory, sticky notes, page-change alerts, and a daily streak. Turn on only what you want.
🔒 Runs 100% in your browser — nothing is uploaded.Five tools, one extension
Each is a toggle. The three page tools share one optional permission, asked only when you enable them.
Site usage timer
See how long you actively spend on each site, bucketed by day. Idle time doesn't count.
No page accessStreak dashboard
Your daily streak in the popup, plus a full stats page — a calendar heatmap, time-per-day, and top sites over any range.
No page accessScroll position memory
Revisit a long page and TabLens drops you right back where you left off.
Page accessSticky notes
Pin draggable notes onto any page. They reappear the next time you're there.
Page accessPage diff monitor
Watch chosen pages; TabLens flags you when their content actually changes.
Page accessLocal-only
Every timer, note, and history entry stays in your browser. No accounts, no servers.
Minimal by default
A fresh install asks for almost nothing. Broad page access is optional — granted only when you switch on a page tool.
Zero setup
No account, no sign-in, no config. Install, flip on the tools you want, and you're done.
How it works
Install and pick the tools you want from the settings page.
Enable a page tool and grant access once — or skip it and keep just the timer & streak.
Open the popup for today's sites and your streak — or the full stats page for your whole history.
