FocusLens tracks your real focus on any learning platform. When you start burning out, an AI tutor steps in — not with a break reminder, but with a quiz that actually rescues your session.
No credit card. Works on YouTube, Coursera, Udemy + more.
Add FocusLens to Chrome. Sign in with your account. Enable it on any learning site with one click.
The extension silently tracks your focus signals — no cameras, no keyloggers. Just mouse, scroll, and reading patterns.
Score drops below 60? The AI tutor appears with a context-aware explanation or quiz. Recover your focus, keep learning.
Tracks idle time, re-scrolls and reading speed every 15 seconds to compute a live cognitive load score.
When your score drops below 60, an AI tutor pops up — not to nag you, but to re-explain the concept in a new way.
See exactly when your brain is sharpest. Daily hourly heatmaps + 30-day calendar view, like GitHub for your focus.
Answer 3 AI-generated questions on your current topic. Get them right and your focus score actually goes back up.
Every Sunday, an AI writes you a personal report: when you studied best, what tripped you up, and what to change.
YouTube, Coursera, Udemy, any college LMS — the extension runs on any learning platform you enable it on.
"I thought I was studying 4 hours a day. FocusLens showed me I was actually focused for 1h 40m. Game changer."
"The AI quiz feature is insane. I hit burnout at 3pm daily — now it catches it and runs a quick quiz. I barely notice I recovered."
"Weekly report told me my Tuesday mornings are my peak window. I moved all hard topics there. My retention doubled."
Install the extension, study for one session, and your first report will genuinely surprise you.
