Hi ProductHunt! 👋 I built Norynth Neural completely from scratch — no frameworks, no chat SDKs, no templates. Vanilla PHP 8.3, MySQL, Groq (Llama 3.3 70B) + OpenRouter fallback, custom CSS design system with dark/light themes. What makes it different: - 9 domain-specific AI contexts (not a one-size-fits-all chatbot) - Stripe subscriptions at $9.99/mo (half the price of ChatGPT/Claude) - Google OAuth + email/password auth - Viral share loops — every shared conversation is a marketing channel - Performance-audited — CPU idle <1%, first paint ~0.4s Free tier: 50 messages/day, no credit card needed. Would love your feedback!

Quick update: Since launching Monday, we've added 2 new features based on early feedback — better domain routing and a free tier (50 msg/day, no CC needed). Still iterating. Would love to hear what features would make this useful for your workflow.
