Show HN: I built a tool to track when AI engines cite your website

Hey HN! I built a tool that tracks when AI search engines (Perplexity, ChatGPT, Claude, Google AI) cite your website in their responses.

*The problem:* AI search is exploding (Perplexity does 100M+ queries/month), but there's no way to know if these engines are citing your content. It's like SEO in 2005 before Google Analytics existed.

*What it does:* - Automated daily checks across multiple AI platforms - Tracks citation rate, position, and trends over time - AI-powered recommendations for queries where you're NOT cited - Shows which platforms cite you most

*Technical approach:* - Puppeteer for web scraping (no expensive APIs) - Firebase for real-time data - Groq for AI recommendations - Next.js + TypeScript frontend - Vercel cron for automation

*Why I built it:* I run llmscentral.com (a repository of llms.txt files) and noticed traffic from Perplexity was growing 50% month-over-month. But I had no idea which queries were driving it. Built this to scratch my own itch.

*Free tier:* 3 tracked queries, weekly checks on Perplexity *Paid tiers:* More queries, daily checks, all platforms, AI recommendations

Would love feedback from the HN community! Happy to answer any technical questions.
