Hey I'm Kacper, Co-Founder of MyArchitectAI, happy to answer any questions about our tool.
@Mike-Amos "idiot box for renders" is a pretty accurate description of what we're aiming for in terms of ease of use. In many cases, you'll get a really good result just by uploading your SketchUp export and pressing 'generate." Then, you can apply any changes like test new materials, add and remove objects, change atmospheres etc.
We're not trying to replace physically-based renderers, as the level of precision of AI image models is still not there (at least for now). We do have plenty of studios that are using MyArchitectAI together with Enscape/TM/Lumion, and I'd say this is the most efficient tool stack right now.
Anyway, if you need to know anything else about our, or other AI tools, just let me know.
