FAQ

Common questions

Yes — completely free. No credit card, no account, no hidden limits. Just paste a YouTube URL and start asking questions. Apatizer is powered by Puter.js which provides Claude AI access at no cost to you.
Most summaries are ready in 2–5 seconds. Longer videos (1 hour+) may take up to 15 seconds as Claude processes the full transcript. Either way, it's dramatically faster than watching the video.
Yes. Once you load a video, you can ask as many follow-up questions as you like. The conversation context is preserved, so you can dig deeper, ask for clarification, or explore different angles without re-loading the video.
Yes. Apatizer handles videos of any length — from 30-second Shorts to 6-hour conference recordings. Claude's large context window allows it to reason over the full transcript at once, not just a chunk of it.
Apatizer supports 16+ languages including English, Spanish, French, German, Portuguese, Japanese, Korean, Chinese, Arabic, and more. You can even ask questions in a different language than the video — Claude handles the translation automatically.
