I'm also enthusiastic, it's not often you see people find a genuinely underserved niche and you have.

I don't know if I would pay £19 for a general state-of-the-area report. I would almost certainly have paid £100-300 for a service that took my planning application, critically reviewed it and told me which aspects were and were not likely to pass, with references to specific examples within my local area.

Thanks, honestly that means a lot! Yeah, the pre-submission review idea is interesting and I've thought about it. I have the data to surface "applications similar to yours in your ward, here's what got approved and what didn't" but I haven't built it as a workflow because it requires the user to upload their plans... and that's a different kind of trust ask, but yeah, it is definitely worth revisiting. £100-500 is also a much more honest price for something that genuinely changes a decision. £19 is in the awkward "too much for curiosity, too little for stakes" zone you and the other commenter are both pointing at.
