How to make a batch of photos uniform (real estate)

I've started working with a real estate agent who asked me to make all the photos in a listing look more uniform, colour-wise.

I asked ChatGPT for help, and it did an awesome job at creating the correct feel; however, the output was a collage (I wasn't able to download the photos individually, even when prompted), and I later noticed that it hallucinated and moved things around.

Is there a platform or cheap processor that can help me complete this task? I have zero experience in photo editing, so ideally I'd just apply a ready-made feature on all my photos and call it a day. Or prompt the thing to adjust the colours to "warm" or something.
