Find the moment behind the answer.

Ask a saved video a question, then use a timestamp reference to jump to the relevant moment. Read the transcript alongside it.

Spend less time scrubbing through a long video. Start with the summary, ask about the part you care about, then open the cited moment in the player.

Reading a document? Ask it a question and follow page, section, or sheet references back to the supporting text.
