PageSage: AI Summarizer for Articles & YouTube

PageSage is an AI summarizer that lives in your browser's side panel — summarize articles and YouTube videos, then ask follow-up questions, without leaving the page. • Summarize articles — open the side panel on any page and get a clear, faithful summary of the article you're reading. • Summarize YouTube — paste or open a video; PageSage summarizes it from its public captions. • Ask follow-ups — keep asking questions about the page without losing your place. • Honest by design — no "credit" games, no padded output. When the AI isn't sure, it says so. • Your notes, your data — summaries are cached locally in your browser, not stored on our servers. • Free to try — a daily free quota with no account, more with a free account, and a Pro plan for heavy users. • Bring your own key — optionally use your own DeepSeek API key for unlimited article summaries; the key stays in your browser and goes straight to DeepSeek. We collect as little as possible. We never sell your data and use no tracking or ad SDKs. See our privacy policy: https://pagesage.net/privacy
