What CleoSum Does
CleoSum is a Chrome extension that analyzes YouTube video content using AI. When you click "Analyze" or "Summarize" on a video thumbnail, we process the video's publicly available transcript to generate insights.
Data We Collect
- Google Account Info: Email, name, and profile picture for authentication (via Google Sign-In).
- Video Transcripts: Publicly available YouTube captions are sent to our server for AI processing. We do NOT store raw transcripts.
- Analysis Cache: Generated analyses/summaries are cached by video ID (not user ID) to serve future requests faster.
- Usage Counts: Daily/monthly request counts for rate limiting.
Data We Do NOT Collect
- Your browsing history
- Which videos you watch
- Your YouTube account data
- Any personal content or messages
- Cookies from other websites
