RepuAI

Track and optimize your brand's visibility in AI search engines - ChatGPT, Perplexity, Gemini. 13-point site score.

Comment

Inspiration

I was searching for my own brand in ChatGPT and Perplexity - and it simply wasn't there. Competitors were being recommended instead. That was the moment I realized: there's no tool to even measure this problem, let alone fix it.

What it does

RepuAI monitors and optimizes brand visibility across AI search engines - ChatGPT, Perplexity, Gemini, and others.

The free Site Checker analyzes any website across 13 dimensions in under 60 seconds:

  • AI bot access - can ChatGPT and Perplexity actually crawl your site?
  • Entity presence - are you on Wikipedia, Wikidata, Google Knowledge Graph?
  • llms.txt - do you have an AI-readable content file?
  • Structured data, page speed, domain authority, and more

Each scan returns four scores: Overall, AI Visibility, SEO, and AEO - plus prioritized fix recommendations with step-by-step instructions.

How I built it

  • Frontend: Next.js + React - fast, server-side rendered, SEO-friendly
  • Backend: Node.js API orchestrating parallel site analysis checks
  • AI layer: OpenAI API for scoring logic and fix recommendation generation
  • Database: PostgreSQL for scan history, monitoring data, and user accounts

Challenges I ran into

The hardest part was defining what "AI visibility" actually means - there's no industry standard. I built a custom 13-point scoring model by testing hundreds of real websites and correlating technical signals with actual AI search results.

The second challenge: running 13 checks in parallel in under 60 seconds without hitting rate limits across multiple external data sources.

Accomplishments that I'm proud of

Getting the Site Checker to work with no signup and return a full, actionable report in under 60 seconds. Most users don't realize how broken their AI visibility is until they see their score - that reaction is the best validation.

What I learned

Most websites fail on basics they don't even know exist - blocking AI bots in robots.txt, missing llms.txt, zero entity presence in any knowledge graph. These are fixable in an afternoon, but first you have to know the problem exists.

What's next for RepuAI

Real-time brand monitoring, competitor benchmarking, and sentiment analysis - tracking not just whether AI mentions your brand, but how.
