Others have mentioned SVG AI tools... I've tried 3-4 over the previous days and eventually ended up with svgai.org (after I've used Google Gemini for bitmap).

You can instruct it to make edits, or say "Use SVG gradients for the windows" and so on and you can further iterate on the SVG.

It can be frustrating at times, but the end result was worth it for me.

Though for some images I've done 2-3 roundtrips manual editing, Nano Banana, svgai.org ...

The advantage is that it produces sane output paths that I can edit easily for final manual touches in Inkscape.

Some of the other "AI" tools are often just simply algorithms for bitmap->vector and the paths/curves they produce are harder to work with, and also give a specific feel to the vector art..
