My Full AI Stack

Every tool I use to build a real AI app with zero developers, what it does, what it costs, and the 3 I'd start with.

Thinking & building

ToolJob in plain wordsCost
Claude (desktop app)My co-founder: planning, strategy, writing, reviewing designs$20/mo
Claude CodeThe builder: lives on my computer, sees my files, writes and fixes the actual appincluded w/ plan
API models (tiered)Inside the app: a cheap model brainstorms, a mid model executes, an expensive model judgesusage: ~$0.001 / ~$0.02–0.10 / ~$0.05 per call

The app's senses & looks

ToolJobCost
Claude Vision (API)Reads photos: garment type, fabric, neckline, occasions~1¢/image
PhotoRoom (API)Cleans photos: background removal + retouch~2¢/image
Gemini image model (API)Generates media: avatar + virtual try-on (one vendor for both = same face every time)~4–10¢/image
FashionCLIP (open-source, on Modal)Meaning-search over the closet ("elegant office look" → the right items)~$10–30/mo GPU, scale-to-zero

Rules I follow with this stack

  1. One vendor behind one thin file. I swapped image vendors twice; each swap = one line of code.
  2. Mock-first. Every AI tool has a fake twin so the whole app runs with zero API keys (and zero cost) while I build screens.
  3. Free tiers are budget caps. No payment method on file = the bill physically cannot surprise you.
  4. The expensive model never does cheap work. Judging only.

If you're starting from zero, get these 3 first

  1. Claude (the $20 plan), your planning partner from day one.
  2. Claude Code, even non-developers: it explains itself as it works; you learn by watching.
  3. Supabase free tier, your data has to live somewhere real, and free-tier-as-budget-cap is the safest way to start.

Everything else joins only when a real feature demands it. Tools you add "just in case" become bills you forget.
