Hi Product Hunt! 👋 I built FastAI Health Coach because every fasting app I tried felt amnesiac — they'd forget my goals every session. So I built one with actual memory. Five AI/ML paths working together: - Claude Sonnet 4 for Coach reasoning + memory of last week's habits - Voyage embeddings for cross-session long-term memory - Claude Vision for meal photo nutrition (calories + macros in 4 seconds) - Claude Haiku for tier-routed classification - A per-user statistical ML model that predicts YOUR weight from YOUR data — not population averages I'm a solo vibe coder. Claude is my pair programmer for everything that's been done before. My judgment is for what's new — when to use Sonnet vs Haiku, embeddings vs fine-tuning, statistical ML vs LLM. The bottleneck moved from typing to deciding. Honest feedback genuinely wanted — what confuses you, what breaks, what's missing. Drop "early access" in a comment → I'll DM the Play Store opt-in link. Drop "build" → I'll send the FastAI architecture diagram. Build log lives at exafabs.ai/blog. Thanks for hunting! — Alpit
