Hey Product Hunt! 👋 Built by a maintenance supervisor with 27 years in the field, not a career developer. **The Problem:** Every AI prototype, every test, every "what if" was burning cash on OpenAI API costs. Maintenance departments can't afford to explore at full price. **The Solution:** AI Optimizer - smart caching proxy for OpenAI API. **Real Results:** - 60% cache hit rate in testing - 60% fewer API calls = 60% savings - Built in over a month, nights after work - First paying customer: March 23, 2026 **What Works:** - Caches OpenAI API calls - 20-40% typical savings (60%+ on repetitive workloads) - Mac + Linux builds - 14-day free trial, $4.99/month - License protection (3-device limit) **Tech Stack:** - Backend: Node.js + Express on Fly.io - Desktop: Electron (Mac + Linux) - Database: SQLite (device fingerprinting, license tracking) - Payments: Stripe (live mode) - Email: Gmail OAuth **What's Next:** - Total saved calculation (v2.0.1) - Enhanced analytics - Multi-model caching (Anthropic, Google) Built nights after work. For maintenance teams exploring AI. For builders on a budget. Happy to answer any questions! GitHub: https://github.com/adamday75/ai-... Landing: https://ai-optimizer-landing.ver...
