Chapter 1
Nobody forced you. That's the clever part.
Somewhere there's a team whose whole job is to keep you watching. They're good at it. They've studied what your thumb does at midnight, what makes you click, what makes you stay. Your willpower is one person. Their system is thousands of engineers and a billion data points.
It was never a fair fight. So stop fighting it with willpower.
Questions people ask
What is Focus Filter?
Focus Filter is a free Chrome extension for students. It blocks YouTube Shorts, hides recommendations and end screens, filters distracting videos by channel and keyword, and can turn blocked videos into memes that tell you to study.
How do I block YouTube Shorts on Chrome?
Install Focus Filter and keep the Shorts option on. The Shorts button is removed from the sidebar, Shorts shelves are hidden and Shorts links are blocked.
Can I see only educational videos on YouTube?
Yes. Hundreds of study keywords and trusted education channels are allowed by default, and Study-only mode blocks everything else.
Is there a YouTube time limit that counts only unrelated videos?
Yes. Set a daily free-time allowance. Only time on videos your filters would block is counted. When it ends, blocking starts instantly.
Does it work on Edge, Brave and Opera?
Yes, on any Chromium browser, using the same install steps.
Is Focus Filter free and private?
It is free. There is no account, no analytics and no server. Your settings stay in your browser.
