What should Clipzy add next?

Hi everyone, I'm Bilal, the maker of Clipzy

Today Clipzy downloads videos from TikTok, Instagram, YouTube, Facebook and Pinterest, saves MP3 audio, and writes AI captions and hashtags for every video.

I'm planning the next tools and would love your input. Which would you use most?

1. YouTube thumbnail downloader

2. Subtitle / transcript downloader

3. Video summary and chapters generator

4. Standalone caption and hashtag generator

5. Something else? Tell me below
