AI Engines

Start with the core pair

ChatGPT and Claude are a sensible starting pair for AI visibility work. Start there, fix the technical signals and content gaps, and widen to other engines when your workflow needs it.

Quick answer
A practical starting point is 2 core engines: ChatGPT and Claude. The engine guides below explain how each AI search engine finds and cites sources. The free AEO Platform AI-readiness check tests technical signals for AI crawlers; it does not query these engines.
Core coverage

Why the default starts with OpenAI and Anthropic

OpenAI

ChatGPT is the default OpenAI surface in the landing narrative. It gives teams a high-signal place to validate mention quality, citation blockers, and competitor pressure before expanding coverage.

Anthropic

Claude is the default Anthropic surface in the landing narrative. It is useful for answer quality, technical clarity, and B2B-style comparison behavior where nuanced wording matters.
