What AI apps have actually stayed on your phone?

I've been realizing I have way too many AI apps installed at this point, and somehow I'm probably still missing a bunch of interesting ones.

Right now I use ChatGPT and Gemini pretty regularly, then there's Days AI, niji・journey, Oshikoi, zeta, Suno... and Acti, which pretty much became my main keyboard after the last beta update.

Gemini has been especially nice for things like instrumental BGM lately, which was not really what I expected to end up using it for.

Anyway, I'm curious what everyone else actually has on their phone.

Not necessarily the obvious ChatGPT / Gemini answers. I'm more interested in the weird, niche, surprisingly useful stuff. Character apps, image/video generation, music, writing, productivity, whatever.

So, what AI apps have actually stuck around on your phone?
