Hey ProductHunt! 👋 I'm Shrikrishna, a student founder from Pune, India. I built PromptQuill because I kept seeing the same problem — developers and founders had great ideas but no structured way to turn them into actionable briefs. ChatGPT gives you one response. PromptQuill gives you 15 structured tabs: → Competitor analysis with real pricing → Technical architecture with cost estimates → Launch strategy with actual copy to send → Monetization math worked out for you → 30-day execution calendar → VC evaluation (Investor Lens) → Honest brutal score (1-10, no inflating) What makes it different: - 6 AI modes: Startup, Coding, Content, Creative, General, Startup Lite - 2 personalities: Bot (structured specs) or Human (expert co-founder voice) - 15 AI providers rotating for reliability - Free forever — 10 generations/day I built this in 3 months while in college, using Supabase, React, and a multi-provider AI router across Groq, Gemini, Cerebras, and more. Would love your feedback — especially on what tabs you'd want added next. Try it free → https://www.promptquill.app
