I suspect that the ADHD audience on HN would skew towards people who have already developed coping mechanisms and systems (and some people seem to have very high intellectual horsepower), so you might not find the best market fit or feedback here. I think I am past the point where this may have been a fit for me, but earlier in my life it may have been very useful.
Edit: Can you explain what "clear boundaries around non-medical use" means?
