Resensa — Ask YouTube & AI Summaries

Ask AI about any YouTube video — get summaries, jump to exact moments by timestamp, and export the conversation.

Watch a 1-hour video in 5 minutes. Resensa adds an AI-powered summary panel right next to the YouTube player, so you can get the key points instantly and ask questions about anything in the video — without rewinding, scrubbing, or hunting through comments for context. What you can do: • Get cited summaries. Every claim in the summary links back to the exact moment in the video. Click any timestamp to jump straight there. • Ask follow-up questions. Curious about something the speaker said? Ask in plain language and get an answer grounded in the actual transcript, with citations to the moments it came from. • Skim or deep-read. Choose a brief overview when you only need the gist, or a detailed breakdown when the topic matters. • Share with one click. Generate a public link to your summary or chat — anyone can read it, no extension needed. Revoke anytime. • Export to Markdown. Drop your summary into Notion, Obsidian, or your notes app with quotes, citations, and timestamps preserved. • Chat history that follows you. All your past conversations are saved across devices and easy to find again.
