Clipfly AI

Clipfly AI is a service with a wide range of tools for creating and editing videos. After registration, you get 20 free credits — enough to try things out. It's not possible to use the AI tools regularly without a subscription.

You can explore all the features here: clipfly.ai/video-ai/, and they're all available once you create an account. There are plenty of genuinely useful ones, like removing the background or watermark from your video.
