SubFocus

Watch only the YouTube channels you choose.

YouTube is full of genuinely valuable content, but it's built to maximize watch time, not your intentions. A quick visit easily turns into an hour down the rabbit hole. Most tools fix this by blocking YouTube entirely. SubFocus lets you keep the good stuff and block the noise by curating an approved list of channels while keeping everything else hidden. • Approved channel list — curate up to 10 channels you trust, added by URL, handle, or one-click while browsing. • Home feed — recommendations, Shorts, and community posts from channels you haven't approved are hidden, replaced with quick links to your approved channels. • Watch video pages — the "Up Next" sidebar and end-screen suggestions are hidden. • Search — only results from your approved channels show while the rest are collapsed with a count of what was hidden (sponsored ads still appear.) • Shorts — the algorithmic Shorts feed is blocked. Shorts from your approved channels still play while Shorts from other channels are blocked with a one-click option to add the channel. • Channel pages — visit any channel normally. On non-approved channels the content is hidden behind a one-click "Add Channel" banner that reveals it. Add channels while you're on their page using a one-click quick-add button or via any handle/URL. SubFocus Premium Premium equips you with the discipline to stay focused. • Stay distraction-free through a work block by locking SubFocus on for a set duration or until a specific time. The off-toggle is unavailable until it ends. • Protect your mornings and deep-work hours automatically through recurring focus schedules (e.g. Mon-Fri 09:00-17:00) where SubFocus can't be toggled off. • Defeat the impulse to disable SubFocus by adding a cooldown timer (your own focus goal is shown back to you while you wait) or require writing a short paragraph before SubFocus turns off. High enough friction to stop a weak moment, but low enough to never trap you. • Unlimited channels for your approved list. When no focus lock is active, toggle SubFocus off at any time to use YouTube normally. Your channel list and settings are stored locally on your device — no tracking, no advertising. Premium licence verification is handled by ExtensionPay. See our privacy policy for details. You choose what you watch, not the algorithm.
