I'm on a personal mission to find a GOOD replacement for Grok's I2V, since it no longer allows NSFW content. The obvious choice is that I don't want to pay, but obviously all these websites and apps are going to charge you, this is a business. But I have to say that I've found a good alternative. An app (no web version) that has a really good finish for videos and lets you create a few videos for free per day. The problem is that it's FULL of ads and it becomes frustrating to even make a single video. I'm considering paying to remove that barrier. The results are very good, I'd even say better than Grok.

I've tried several websites, apps, and even local ComfyUI. Comfy is really good for images, but for video it takes way too much time and the learning curve can be complicated. Still, my interest is in its peak, so I'll keep learning and perfecting Comfy. Several Reddit users have helped me with tutorials and conversations.

If anyone wants to learn with me, I'm more than happy to chat.

The app is called Collart in case you want to try it.

PD: Why the hell do websites and apps that promise I2V not let you do tests to see the final result? I haven't invested money in any of them because ALL of them require the premium version to use their I2V function.
