Does Synapse summarize the video by itself?

Synapse extracts and prepares the transcript, then sends the context and your chosen instruction to supported AI tools for the response.

Can I use a custom prompt with a YouTube transcript?

Yes. You can select prompts from the Synapse Prompt Library or configure a custom extraction instruction.

Do I have to leave the YouTube page?

No. YouTube Extract runs in the Synapse sidebar beside the open video.
