About AI Video Summary
AI Video Summary is a video and audio intelligence platform at aivideosummary.com. It is not only a YouTube summarizer. The product extracts subtitles and captions, generates full transcriptions, and produces structured AI summaries, chapters, highlights, action items and transcript-grounded chat.
YouTube processing is live in Phase 1: paste a public URL, discover caption tracks, clean the transcript, then run GPT-5 nano analysis. Uploaded MP4/MOV/WEBM video and MP3/M4A/WAV audio are specified for Phase 2 and are not processed yet.
We prefer existing YouTube captions before speech-to-text, never invent missing subtitles, and keep original uploaded media temporary when that pipeline ships.
