13Gemini

Google's AI, and it has two aces.

First - images and video. Google is clearly ahead here. Image generation is excellent, and video through Veo looks good enough that you just sit and watch for a while. All of it is in the normal subscription, nothing extra to pay.

Second - volume. Gemini can hold an enormous amount in its head at once. Throwing a huge document or a pile of files at it and asking it to make sense of them is its home turf.

It's fine for code too, though I prefer other things. But if your project is about visuals - covers, images, clips - I'd take this one.

Google also has NotebookLM: you drop your own material in and it turns it into notes, a summary, even a podcast with two hosts. Unexpectedly pleasant for studying.
