The Problem
Businesses can check their Google rankings, but no one was telling them whether AI assistants (ChatGPT, Gemini, Perplexity) recommend them. As AI search grows, being invisible to these engines means losing customers — and there was no tool to measure it.
The Solution
Duelly.ai queries multiple AI engines and traditional search simultaneously, analyzing whether your business gets cited, recommended, or mentioned. It combines this with a deep site audit (technical SEO, schema, content quality) to give a unified visibility score across three dimensions: SEO, AEO, and GEO.
Architecture & Technical Decisions
- Multi-Engine Querying: Parallel requests to ChatGPT, Gemini, and Perplexity APIs to check citation/recommendation status
- Site Audit Engine: Custom crawl + Moz API for domain authority, backlink data
- AI Analysis: Gemini for interpreting raw audit data into actionable recommendations
- Credit System: Per-scan pricing model with Stripe
- Real-Time: Results stream back as they complete (no waiting for all engines)
