Possiber turns any playlist into a clean, distraction-free study queue. No recommendations, no comments, no autoplay rabbit holes — just the videos you chose to learn from.
Free forever for 2 playlists. Available for Chrome & Edge.
Every feature does one thing: keep your attention on the lesson in front of you. Here's what that looks like.
Open a new tab and Possiber greets you with what's next — not a feed. One glance shows what you're studying and how much is left.
Flip a single switch and the noise is gone. No settings maze — focus is on or off, and you decide the instant you need it.
A progress line tracks the whole playlist, and each lesson gets a checkmark when you finish it. Momentum you can actually see.
Close the tab, come back tomorrow — Possiber remembers your place. No hunting through a playlist to find where you were.
Work in focused rounds with timed breaks. The timer runs alongside your video — no separate app, no switching tabs. Complete a session and earn coins. The longer you focus, the more you earn.
The three biggest attention traps on YouTube — the recommendation sidebar, the comments section, and the "Up next" feed — are gone. What's left is your video.
Complete a focus session and earn coins — the longer you focus, the more you earn. Stop early and you lose some. It's a simple loop that keeps you coming back.
See every playlist at a glance. Search across all your videos, toggle progress dots, hide watched lessons, and sync with one click. It's everything you need in a single view.
Dark and Light are free. Paper and Midnight are Pro. Pick the one that fits your study environment — or switch whenever you feel like it.
Trying to leave a focus session? Type your custom focus phrase or solve a quick math problem. It's a small friction that stops you from quitting too early.
Need Spotify for study music or Notion for notes? Add any domain to the whitelist and Possiber will allow it during focus sessions. YouTube is always allowed.
Try to open Reddit, Twitter, or any non-whitelisted site during a focus session? Possiber blocks the navigation and redirects you back to your playlist. No willpower required.
Organize playlists into folders — Physics, Chemistry, Side projects. When your library grows, collections keep everything easy to find. Pro feature.
Create study tasks and link them to specific videos in your playlists. Check them off as you go. Your to-dos stay in sync across devices. Pro feature.
Watch a video past 90% and Possiber marks it done automatically. No checkboxes, no manual tracking. Just watch and learn.
Download all your playlists, progress, and settings as a JSON file. Restore it anytime. Move between browsers or keep a backup — your data is never locked in.
Earned enough coins? Spend them on cosmetic themes and items in the Coin Shop. The more you study, the more you unlock.
No trials, no credit card to begin. Pay monthly, save with yearly, or own it for life.
It runs on top of YouTube in your browser and strips away everything that isn't your study video — recommendations, comments, Shorts, and autoplay suggestions. You build playlists of the videos you actually want to learn from, and Possiber plays through them cleanly.
Chrome and Edge. It installs as a browser extension from each browser's store.
Free gives you up to 2 playlists stored locally on your device, with the full distraction-free player and no account required. Possiber Pro ($5/month, or $42/year which works out to $3.50/month) unlocks unlimited playlists and syncs them across all your devices. If you'd rather not subscribe, Lifetime is a single $195 payment that includes Pro and all future updates, forever.
Pro subscriptions are handled securely by Paddle, our payment provider. You can pay monthly or yearly, and Paddle manages your invoices and payment details — we never see your card information.
No. Possiber never collects your browsing history or YouTube watch history. On the free tier, your playlists live only on your device. On Pro, we store your email (for login via Google) and your subscription status — nothing more.
You can cancel anytime from your account. Your subscription stays active until the end of the billing period, then drops back to the free tier — your playlists aren't deleted.
No. Possiber only cleans up the pages you're already viewing and plays embedded videos. It doesn't log into, post to, or read anything from your YouTube account.

Coins are rewards you earn by completing Pomodoro focus sessions. The longer you focus, the more coins you get. For example, a 30-minute session earns 30 coins, a 60-minute session earns 70 coins. If you stop a session early, you lose some coins proportional to how far you got.
The Dashboard is a full-screen view of all your playlists. You can switch between grid and list view, search across every video in every playlist, toggle progress dots, hide watched lessons, and trigger a manual sync with YouTube.
Collections let you organize playlists into folders — like "Physics", "Chemistry", or "Side projects". They appear in the Dashboard and help you keep things tidy when you have a lot of playlists. Pro feature.
Free gives you Dark and Light. Pro adds Paper (warm cream tones) and Midnight (deep dark with neon accents). You can switch themes anytime from Settings.
