I use it for all my non-professional work and I find it works well enough for me.

Mostly for things that I know are possible and have a vague idea of how I would do it, but it would take me longer. Some examples in no particular order:

* Made my wife's travel blog/site

* Chrome extension for Crunchyroll to allow multisubs + local translation for unsupported languages (so my wife and I can watch and she doesn't need to focus extra hard reading English)

* Same as above for Netflix

* Setup multi subs with mpv (some Lua plugin shenanigans)

* Setup proton for warcraft 3 + wc3 champions (unofficial ladder) on Linux

* Setup a bunch of xrandr aliases for my different monitor uses (I'm still on x11)

If you need a custom chrome/firefox extension or to create some bespoke Linux QoL stuff, it works great. This was all Gemini Flash 3.5-3.7 (been using it for a while). I suspect pretty much anything would succeed at these tasks, but I just stick with antigravity because it works for me(and I'm on some discounted plan).
