Hey Product Hunt! 👋 I built PromptGap after a frustrating discovery — when I searched ChatGPT for tools in my niche, it always recommended the same brands. Never mine. I had no idea this was even happening. That's the problem: AI models like ChatGPT, Claude, and Gemini are becoming the new search engine for buyers. If you're not being cited, you're invisible — and you don't even know it. PromptGap scans 30+ buyer-intent queries across GPT-4o, Claude & Gemini, shows you exactly how often your brand gets cited vs. competitors, and gives you a prioritized fix plan: blog topics to write, llms.txt to add, and quick wins to close the gap. It's free to start — a scan takes 60 seconds. Would love your feedback and happy to answer anything! 🙏
