Thanks for the feedback.

On your questions. I'm doing this solo. I'm on a Vercel paid plan, so costs are reasonable (for now) but I've really only shown this to family and friends at this point, so the userbase is tiny.

I have a few family members and friends who are healthcare providers (including those with MD attached to their name) who have provided a lot of guidance. Our friend and family network also includes several with kids and adults on the spectrum, and we have sought out their advice/feedback. But as you surmised, I did rely on AI, specifically for generating all of the media (images/video clips) to fit various scenarios.

On whether the exercises are helpful -- that's exactly the type of data I would love to get, but the site is quite new. If you have ideas on how I can determine that I'd welcome it.
