Built an AI decision analysis tool in one weekend — here's what I shipped

Idea: you describe any decision in plain text. Claude builds an interactive decision tree, calculates expected monetary value, highlights the optimal path.

Stack: Claude API + Stripe + vanilla JS. Free tier + $9/mo Pro. Live at decisions.alanhalley.com.

I'm 74, been in software 30+ years, building from Ilhéus, Brazil. AI tools changed what's possible in a short engagement — this used to be a month of work.

Available for prototyping engagements if anyone needs something made real fast. $500–$5K.
