Is Youtube Summarizer - Syllaby safe?

Clean risk

Youtube Summarizer - Syllaby sends user-clicked YouTube transcripts and titles to Syllaby's prompt API.

When a user clicks the extension's summary control on a YouTube watch page, it fetches the video's caption text and builds a prompt with the transcript, video title, and YouTube ID. The extension sends that prompt data to Syllaby's API to generate the summary.
