🎌 Samuraize
Summarize long YouTube videos, however long they are
Click to switch summarizer Summarizer
Paste a YouTube link and Samuraize carves it into a short, bite-sized document of its key points — no need to watch the whole thing.
Most summarizers quietly cut off after the first hour or return a summary that only covers the beginning. Samuraize splits long transcripts into parts, summarizes each one, and stitches them back together in order, so a five-hour stream gets a summary that actually reaches the end. Paste a link above to try it - three summaries are free without an account, and a free account gives you 20 Samurai Coins a month (1 coin per 10 minutes of video).
How long videos are handled
A transcript is broken at timestamp boundaries into chunks of roughly 25 minutes of speech. Each chunk is summarized with a note about where it sits in the whole, then the sections are merged in order. The result reads like one document, and every section still links to its moment.
Control how much detail survives
The detail slider goes from 5% up to 50%, depending on your plan. At 5%, a three-hour talk show becomes a page you read in two minutes. At the top end, you get a thorough section-by-section account you could use instead of watching.
Then search inside it
Long videos are exactly where 'Ask' shines: instead of re-watching to find the one thing, ask 'when did they talk about the merger?' and get the answer with a timestamp.
Frequently asked
- Is there a maximum length?
- No hard limit. Extremely long videos (10+ hours) are condensed more aggressively so the summary stays readable.
- Does a long video use more of my quota?
- No - one video is one summary, however many parts it took.
- Why did a video fail before?
- Older tools time out on long videos. If a video ever fails here, it's almost always because YouTube has no transcript for it - and we tell you so immediately.
