Study smarter, not longer! Add videos, select the key moments to remember, and let Vline tell you when to review them to strengthen your long-term memory. _____ How it works 1. Add your YouTube videos directly in the app — paste a link manually or use the Vline extension from YouTube, Safari, or any YouTube link. Already have playlists? Import them instantly from the app! 2. Organize your videos with albums, sub-albums, favorites, and custom tags. 3. Use chapters to navigate quickly through different sections of a video. 4. Add vlines to mark the moments you want to review, give them a title, and even add notes to better retain what matters. 5. Review your vlines anytime to reinforce your knowledge. 6. Add your videos to your review plan to get notifications when it’s time to rewatch them — based on the proven science of spaced repetition. Then, enable Focus Mode to play only your vlines and stay concentrated on what truly counts. _____ Why choose Vline • Save time by focusing on what’s essential. • Retain what you watch for longer. • Turn any YouTube video — lecture, interview, documentary, or tutorial — into a powerful learning resource. • Enjoy a clean, elegant, and distraction-free interface designed to boost focus. _____ Key features • Add videos and import YouTube playlists. • Organize with albums, sub-albums, favorites, and tags. • Highlight and manage key moments using vlines. • Smart reminders based on spaced repetition. • Focus Mode to replay only what matters. • Smooth, intuitive interface built for effortless learning. _____ Learn better.
