FREQUENTLY ASKED QUESTIONS
━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q: What types of YouTube videos does it work with?
A: LectureLoop works best with educational content that has auto-generated or manual captions. It uses the video transcript as input. Videos without captions cannot be summarized.
Q: Does it work with any language?
A: LectureLoop can process transcripts in any language supported by YouTube captions. The summary output language can be set to English, Japanese, Korean, or Spanish.
Q: Is the AI summarization accurate?
A: LectureLoop uses large language models for summarization. Results are generally accurate for structured educational content, but AI can occasionally misinterpret complex or highly technical material. Always cross-reference with the original video for critical information.
Q: Does LectureLoop send my video data to a server?
A: Yes — the video transcript is sent to a secure API proxy (s-hub-dashboard-beta.vercel.app) for AI processing. Only transcript text is transmitted. No account data, viewing history, or personal information is included.
Q: Can I use it on private or unlisted YouTube videos?
A: LectureLoop can only access transcripts for videos you can view in your browser. It does not bypass YouTube's privacy settings — if a video requires login to view, it must be accessible to your account.
