Use it every day

Honestly didn't expect to like it this much. AI-generated YouTube video summaries is exactly what I needed, and saves time on long videos. but I reach for it almost every day now and it just clicks.

Solid for our team

We rolled this out across the team last quarter and easy to use with YouTube links. AI-generated YouTube video summaries fits neatly into how we already work, and useful for research and learning workflows removed a step we used to do by hand. Summary quality depends on video transcript accuracy, which is the main caveat, but it has held up under daily use.
