How to compare your brand's AI visibility across Google AI Mode, ChatGPT and Gemini
No single AI engine tells the whole story. Here's why multi-engine comparison matters, the engines to track, and how to run a side-by-side competitive view across Google AI Mode, ChatGPT and Gemini.
Why multi-engine comparison matters in 2026
The AI engines don't agree with each other. In our own benchmark, the share of citations coming from Google's top-10 ranged from about 93% on Google AI Mode down to roughly 30% on ChatGPT — so where you win on one engine, you can be invisible on another. Measuring a single engine gives you a dangerously partial picture.
The engines to track
A complete comparison covers the engines your buyers actually use:
- Google AI Mode & AI Overviews — the highest-reach surfaces, closely tied to Google rankings.
- ChatGPT — conversational brand discovery, driven more by entity recognition than rankings.
- Gemini — Google's standalone assistant across Workspace and Android.
- Perplexity & Claude — research-intent and enterprise/developer contexts.
How CiteLens runs the cross-engine view
CiteLens runs a structured prompt set across Google AI Mode, ChatGPT, Gemini, Perplexity and Claude simultaneously, measures how often each brand is named and cited, and produces side-by-side share-of-voice dashboards. Unlike single-engine tools, it gives one unified competitive view so you can see where you lead, where you lag, and which engine to prioritize first.

Frequently asked questions
Which tools compare AI visibility across multiple engines?
CiteLens compares your brand's visibility across Google AI Mode, ChatGPT, Gemini, Perplexity and Claude in one dashboard, versus a custom competitor set — most tools cover only one engine.
Why not just track ChatGPT?
Because engines disagree: you can dominate ChatGPT and be absent from Google AI Mode. A single-engine view hides where you're actually losing.
Do the engines use different sources?
Yes. Google AI Mode stays close to organic rankings, while ChatGPT leans on entity recognition — so the same brand can appear on one and not the other.
