// Problem

ChatGPT hallucinated on Apple APIs. I needed HealthKit help but couldn't find reliable AI for Swift.

// Solution

Scraped Apple's documentation into structured knowledge bases. Each framework got its own GPT with RAG grounding for citation-backed answers.

// What I Built

Directory site linking to 38 framework GPTs (SwiftUI, CoreML, HealthKit, ARKit, etc.). 16 MDX blog articles. Promoted on r/swift—100K users in the first week and adoption by Apple's Swift team.

// Technologies

TypeScript Scraper

Crawled Apple docs into structured JSON for GPT knowledge bases.

// Lessons Learned

  • 01Timing beats polish. Launched right after GPT Store announcement—being first mattered.
  • 02Reddit works if you solve real problems. Genuine value compounds.
  • 03RAG quality depends on source quality. Gold in, gold out.
