You should take a look at Baitblock (https://baitblock.app). We're working on something called the "Intelligent Blocker" (not yet in production, almost complete) that understands how you get to distractions in the first place. Then it removes the distracting types of comments, posts, search results, recommendations, links etc from the internet while you're working on studying.

Its kind of complex but works perfectly in trials. We also have the YouTube recommendations hider feature in the app.

Give it a shot and LMK what you think.
