Lilys AI (Video and Document Summaries)
A Korean-made service that summarizes YouTube videos, PDFs, web pages, and audio. Beyond summaries it can explain the content in simpler terms or let you keep asking questions about the material. For videos it shows a timestamped transcript alongside a Korean translation.
How to try it
Press "Start for free" on the front page, then paste a YouTube link or upload a file to generate a summary. From the result screen you can view the transcript or keep asking follow-up questions. Korean is supported, and files you upload are sent to the operator's servers for processing.
