Frequently asked questions
Does it work with any YouTube video?
Yes, as long as the video is public. We handle videos from 2 minutes to 4 hours, in any language.
What if the video has no subtitles?
Most videos have auto-generated YouTube subtitles. Otherwise we attempt an audio transcription, but it's not 100% guaranteed.
How long does it take?
Usually less than a minute for a 30-minute video. The longer the video, the longer it takes — but it stays very fast.
Can I cancel anytime?
Yes, in one click from your account. No commitment, no questions asked.
Is my data private?
Yes. Your videos and conversations stay private. We don't resell them and we don't use them to train models.
Why only €5/month?
Because the tool should stay affordable. You don't need to charge €30 to do the job well.
Are my summarized videos saved?
Yes. Every video you summarize is filed in your library: you can find it again, organize it into collections and search it anytime.
Can I ask a question across all my videos?
Yes. Search by meaning analyzes your whole library and gives you a synthesized answer, citing the relevant videos.
What's the "anti-fluff" rating?
Each video gets a Concision rating from the AI, measuring filler and digressions, plus a Value rating you give yourself. At a glance you know whether a video gets to the point — or if the summary is enough.
Can I share my videos?
Yes. Turn on your public profile (sumyt.net/u/your-handle), make the videos of your choice public, and share your annotated selection with a single link — with a clean preview on WhatsApp and social media.
What's the queue?
When you add a video, it goes into your queue and Sumyt processes it in the background. You can queue several in a row and move on while they get summarized.
