HubSpot's AEO Grader is a free tool that scores how AI assistants perceive your brand across a few engines. It's a polished lead magnet — useful for a quick snapshot, and a funnel into HubSpot's broader marketing platform.
meraGEO overlaps on the free part: a free, no-signup scan across ChatGPT, Claude, and Gemini. The difference is what happens next. The grader tells you the score; meraGEO also offers a $19 report with the actual fixes — a custom llms.txt, AI-optimized FAQ, comparison content, citation targets, and an improvement plan.
