EVERYTHING YOU NEED
A complete video watching experience with transcripts at your fingertips.
LIVE SUBTITLE OVERLAY
Real-time synced subtitles displayed directly on the video. For default captions, two segments are shown simultaneously so the spoken text is always visible — no more lag.
DEFAULT & ASR SOURCES
Toggle between YouTube's built-in captions and AI-powered Audio Speech Recognition. ASR provides more accurate timestamps and works even when YouTube captions don't exist.
ON-DEMAND TRANSCRIPTION
No transcript yet? Extract one directly from the viewer — choose Default or ASR. Credits are deducted automatically. No need to leave the page.
SUBTITLE CUSTOMIZATION
Control font size (12-36px), text color, background color & opacity, and subtitle position (top, center, bottom). Make subtitles work for your setup.
SYNCED TRANSCRIPT SIDEBAR
A collapsible side panel shows the full transcript. It auto-scrolls with playback and lets you click any segment to seek the video to that exact moment.
