Framemarker: Visual Library by Theo Miranda

Framemarker is a visual highlighter for YouTube.

Capture the exact frame you want to remember, keep its timestamp, add a quick note, and return to that moment whenever you need it. It is built for creators, editors, motion designers, filmmakers, researchers, students, and anyone who collects visual references from video.

Press H while watching a YouTube video to save the current frame. Framemarker adds visual pins directly to the YouTube timeline, so your saved moments stay connected to the video itself. Hover a pin to preview the frame, click it to jump back to that timestamp, or open the side panel to review, edit, and delete saved frames.

Your archive can stay local on your device by default, with no account required. You can also connect a cloud account to sync your saved frames across devices.
