Page Copilot by Alon

Compare webpages and videos across tabs with AI, then summarize and ask follow-up questions with your own API key.

Page Copilot by Alon helps you compare webpages and videos across tabs with AI. Use it to compare articles, products, viewpoints, and video content without copying everything into a separate chat app. It can also summarize the current page, answer grounded follow-up questions, and work with readable transcripts from YouTube and Bilibili when captions are available.
