A dedicated YouTube flow for transcript-heavy videos, interviews, and tutorials.

Lecture Recap

Input

45-minute Stanford lecture on decision theory

Summary

The recap pulls out the thesis, the core examples, and the conclusions so you can revisit the lesson without replaying the whole video.

Interview Summary

Input

2-hour podcast interview with an AI researcher

Summary

The summary condenses the guest’s main arguments, strongest quotes, and the points that shaped the rest of the conversation.

Tutorial Takeaways

Input

20-minute Figma tutorial on auto-layout

Summary

Instead of scanning a long transcript, you get the steps, tools, and practical tips in a compact format you can copy elsewhere.

What's Live

Transcript summary now; comment synthesis next

This page summarizes the video transcript. It does not currently fetch comment text, group audience themes, or measure disagreement. That verified demand is scheduled as a product capability, with sample-size and missing-comments disclosure required before launch.

After a successful saved summary, tap Study with flashcards. The owner-bound handoff sends the bounded summary text to StudyBot; it does not send the raw video or transcript source anchors.

How to use it

01

Paste a YouTube link with captions into the tool above.

02

Choose the output format you want before running the summary.

03

Copy the recap or continue in the full dashboard workspace.

This tool handles

  • Public YouTube videos with captions (creator-uploaded or auto-generated)
  • 4-tier transcript fallback — youtube-transcript-plus → innertube → Supadata native → Apify starvibe — so most videos extract on first try
  • Lectures, interviews, podcasts, tutorials, news segments, conference talks
  • Bullet, paragraph, key-takeaways, and TL;DR output formats — all length-capped
  • Video title and channel name preserved in the summary header
  • Output language matches the user's interface language (EN, RU, others on the way)

Not in scope

  • Videos with disabled captions and no auto-captions — there is no transcript to summarise
  • Music videos (lyrics-only) — the summary collapses to a thin paragraph; use a lyrics tool instead
  • Live streams in progress — Caption stream isn't finalised yet; wait until the stream ends
  • Age-restricted, paywalled, or unlisted videos that require login — the public scrapers don't see them

Try the YouTube summariser above on a real video URL. The deep-dive below covers which video types compress best, what the 4-tier transcript fallback actually does, and when a manual watch beats any summary.
