You have a 45-minute video and one specific question. Re-watching to find the answer is slow; re-reading a 6,000-line transcript is slower. A chat with a transcript reads the whole video and answers directly — and it tells you when the answer is not in the video, so you know when to trust it.
What you get
- Q&A over one video — ask as many questions as you want about the video you loaded.
- Grounded answers — the model answers only from the transcript. If the video doesn’t cover your question, it says so instead of guessing.
- Real details — names, numbers, dates, product names, and short quotes are kept from the transcript, so the answer is specific, not vague.
- A running session — the conversation is stored per video, so you can come back and keep asking.
- Same language as the video — ask in the transcript’s language; the answers follow it.
- Works without captions — videos with no caption track are transcribed with AI speech recognition first.
How it works
- Extract a video with the tool (or paste its URL and press Extract). The transcript loads.
- In the Chat with the transcript panel, type a question.
- A large language model reads the full transcript and answers — grounded in what the video actually says.
- Keep asking. The conversation is stored, so you can resume it.
Why grounded, not general-knowledge, answers?
A general chat model will happily answer anything — but for a specific video you want the answer to be about that video, not a plausible-sounding guess. Grounding the model to the transcript and telling it to say “not mentioned” when the video doesn’t cover a topic is what makes the Q&A trustworthy: you can tell when an answer is really in the video and when it is a gap.
What people use transcript chat for
- Quick answers — “What’s the main point?” or “What did they say about pricing?”
- Fact-checking — confirm a number, name, or claim that was in the video.
- Study & revision — quiz yourself by asking the model to explain a concept from the lecture.
- Research & quoting — pull the exact lines that support a claim, then cite them.
Transcripts, chat, and more — same tool
Chat is one feature of the tool. The same URL also gets you the full transcript with timestamps, an AI summary, a study quiz, flashcards, a mind map, a study guide, SRT/VTT subtitle downloads, translation into 100+ languages, and an REST API + MCP server if you want grounded Q&A in your own pipeline.
