"AEO grader" is the fastest-growing search term in the whole AI-visibility category right now, and most of the pages that rank for it only mention one tool: HubSpot's AEO Grader. It's a fine starting point, but it's a static rubric, not a live check, and it's the only well-known name in the space. Here's what a grader actually measures, and the free and paid alternatives worth knowing about.
Short answer: if you want a free, no-signup check of whether ChatGPT actually names your brand today, use AEO Copilot's free checker. If you want an ongoing, multi-engine tracking platform instead of a one-time score, AEO Copilot's paid plans start at $9/month for all 4 major LLMs (ChatGPT, Claude, Perplexity, Google AI Overview), or see Peec.ai and Profound for the higher-priced, enterprise-oriented tracking platforms.
What an "AEO grader" actually measures
A grader like HubSpot's AEO Grader scores your site against a fixed rubric: schema markup, content structure, crawlability signals, and similar technical checks. It's fast and free to get a number, but the number is a prediction of AI-readiness, not a measurement of AI behavior. A page can score well on the rubric and still never get mentioned when someone actually asks ChatGPT about your category, because the model's answer depends on more than any single page's markup: brand mentions across the web, competitor positioning, and how the model interprets the question.
That's the gap a live AI visibility check closes. Instead of grading a page against a checklist, it sends a real prompt to a real model and reports whether your brand shows up in the actual answer.
Free AEO grader alternatives
AEO Copilot's free AEO checker runs a real prompt against ChatGPT and tells you whether your brand appears in the answer, then layers 6 technical readiness checks (schema, sitemap, indexability, page speed, structured data, llms.txt) on top. No credit card, no email gate, and it doubles as an AEO score checker that tells you where you stand today, not just whether a page is technically ready.
Paid AEO tracking platforms (beyond a one-time grade)
A grader gives you a snapshot. If you need to track visibility over time, across multiple prompts and competitors, you need a tracking platform instead. The three most-searched names in this category:

Why AEO Copilot instead of a static grader
The core difference is behavioral, not technical. A grader tells you what should work. A live prompt tells you what did.
- It's a real answer, not a score. You see the exact text ChatGPT returned, including which competitors it named instead of you, not just a number out of 100.
- It's free with no gate. No email required to get your result, unlike most lead-gen-style graders.
- It scales into tracking. The same methodology that powers the free checker runs on a schedule in AEO Copilot's paid plans, so a one-time grade can become ongoing visibility tracking across ChatGPT, Claude, Perplexity, and Google AI Overview without switching tools.
Who should use which
- Just want a quick technical score: a rubric-based grader like HubSpot's is fine for a first pass.
- Want to know if ChatGPT actually mentions your brand today, free, no signup: AEO Copilot's free checker.
- Want ongoing tracking across 4 engines on a real budget: AEO Copilot's Startup plan at $9/month.
- Want an enterprise platform with content briefs and compliance paperwork: Profound.
Frequently asked questions
Is there a free AEO grader tool?
Yes. AEO Copilot's free checker is a free AEO grader alternative: it runs a live ChatGPT prompt against your brand and layers 6 technical AI-readiness checks on top, with no signup and no credit card.
What's the difference between an AEO grader and an AEO checker?
A grader scores a page against a fixed technical rubric (schema, structure, crawlability). A checker like AEO Copilot's sends a real prompt to a real model and reports whether your brand actually appears in the answer. The rubric predicts readiness; the live check measures behavior.
What is the best HubSpot AEO Grader alternative?
For a free, no-signup option, AEO Copilot's checker runs a live ChatGPT prompt instead of a static rubric. For ongoing multi-engine tracking, AEO Copilot's paid plans start at $9/month with all 4 major LLMs included; see the full comparison for how it stacks up against Peec.ai and Profound.
Does an AEO score predict actual AI mentions?
Not reliably on its own. A technical score tells you whether a page is structured in a way models can parse and quote, which matters, but it doesn't tell you whether the model actually names your brand for a real question. The two are complementary: fix the technical gaps a grader finds, then verify the fix worked with a live prompt check.
