SlideTrail

Look back. Keep watching. Keep earlier lecture slides beside your YouTube video.

SlideTrail keeps earlier slides beside your YouTube lecture, so you can look back without interrupting playback. Need to check a definition, revisit a diagram, or connect an equation to the previous slide? Browse your slide trail while the lecturer continues explaining. Spend less time rewinding and more time understanding. With SlideTrail, you can: - Automatically save stable slides as you watch. - View earlier slides without pausing or seeking. - Select the presentation area to leave out a moving presenter. - Pin important slides and add your own notes. - Find saved slides by timestamp or note. - Remove unwanted slides with a quick Undo option. - Download slide images and export timestamped notes. - Jump back to a slide’s moment when you want to revisit the explanation. Built for students and anyone learning from video lectures, SlideTrail keeps useful context within reach. Saved slides and notes are encrypted locally on your device, with no account required. Open a YouTube lecture, click SlideTrail, and start capturing. Your slide history builds from that moment.
