Q. How does the AI summarizer work?
A. We pull the video's transcript using YouTubeTranscript.dev's core engine, then feed it to a large language model that returns a TL;DR, key takeaways, and bullet points in under 10 seconds.
Q. What's the maximum video length?
A. Up to 4 hours. Longer videos are chunked and summarized hierarchically — we summarize each chunk, then summarize the summaries.
Q. Is this really free?
A. Yes. 3 free summaries per day with no account needed. Sign up free (email only) for 100 credits/month, where each summary costs 1-3 credits depending on video length.
Q. Which AI model do you use?
A. We use a frontier LLM optimized for instruction following. The exact model rotates based on cost and performance benchmarks.
Q. Are summaries accurate?
A. Summaries reflect what's in the transcript. If the video has bad auto-captions, summary quality suffers — we recommend videos with manually uploaded captions for critical use.
Q. Can I use this via API?
A. Yes. POST a video URL to /v1/summarize and get JSON back. See API docs for details.
