YouTube → summary
Summarize a YouTube video from its transcript, not from a black-box recap
Search “YouTube summary” and you often get a model that watched nothing and billed you. Here the source of truth is the caption file. We build a chapter-aware recap from those lines, and we also copy a tight prompt so you can paste the transcript into the LLM you already pay for.
How to summarize a video here
Load captions
Same paste-a-link flow. Chapters come from YouTube when the creator set them.
Read the recap
Each chapter (or the whole talk) gets the opening sentences of that span — extractive, not hallucinated.
Optional: your model
Copy the Summary prompt (transcript included) into ChatGPT, Claude, or a local model for a tighter rewrite.
Why this beats a one-shot “AI summary” site
You can check the cues
Every claim in the recap is a slice of the transcript you can open underneath.
Chapters matter
A 2-hour lecture is not one paragraph. We split on creator chapters when they exist.
You keep the model
We do not lock summaries behind our API meter. Prompts are local copy.
Same tool family
After the recap: download SRT, translate, or grab audio.
Summary intents that are actually different
Conference talk
Use chapters as an outline; skim the recap before committing 40 minutes.
Study notes
Copy the Notes prompt instead of Summary — headings and glossary, still from captions.
Quote hunting
Use Quotes prompt, then click timestamps in the transcript.
Limits
Garbage captions in, garbage recap out. We do not watch the pixels, so visuals-only jokes and slides without speech will not appear. No chapters means one recap for the whole file.
FAQ
Do you use GPT on our servers?
No. The on-page recap is extractive (sentences from the captions). The Summary button copies a prompt for your own model.
How long does it take?
Caption fetch is usually about a second. The recap is instant after that.
Can I summarize a clipped range?
Trim the cues first, then copy the Summary prompt — it uses visible lines.
What if auto-captions are messy?
Edit obvious errors, then recap/copy. We do not clean ASR for you.
Is it free?
Yes. Same AdSense-around-the-flow model.
