YouTube video timestamp creation support tool
A free tool to help you create timestamps for YouTube videos. With an intuitive interface, you can easily create and edit timestamps. For advanced users, shortcut keys enable faster and more efficient workflow.
The extension uses Google's Gemini API to semi-automatically summarize subtitled videos under 12 hours, helping users quickly understand key points without watching entire videos. Summaries are stored locally for future reference.
OSHIStamp provides preset fast-forward/rewind buttons (1s, 5s, 10s, 1m, 5m, 10m) plus custom intervals, playback speed selection (0.5x to 2.5x), and keyboard shortcuts for hands-free control during active viewing.
OSHIStamp enables one-click timestamp insertion during playback with customizable formats (short or full), keyboard shortcuts for rapid workflow, and automatic local storage. Users can jump to timestamps and organize multiple videos' timestamps in a centralized memory list.
The extension automatically saves all timestamps to local storage and offers JSON export/import for manual backup. Google Drive auto-backup support enables data recovery after Chrome reinstalls, OS changes, or profile deletions.
Users can take PNG screenshots directly from videos, create playable timestamp links for sharing, and display custom fan images to boost motivation. All data stays local and private with no developer collection.
