HubSpot AEO Grader vs Relixir

Which one should you pick?

Based on the published data, Relixir lists the broader engine coverage (4 vs 3); only HubSpot AEO Grader offers a free tool. Positioning also differs: HubSpot AEO Grader aims at a quick free brand perception check, while Relixir targets B2B teams automating AI search visibility workflows. There is no universal winner — shortlist by the engines you need, your budget, and whether you want to try before you buy.

What is HubSpot AEO Grader?

HubSpot's AEO Grader is a free, one-time tool that checks how ChatGPT, Perplexity, and Gemini describe a brand based on their training data. It scores five dimensions — sentiment (up to 40 points), presence quality (20), brand recognition (20), share of voice (10), and market competition (10) — after users submit company name, location, industry, and product. The result is a composite score out of 100 with a written breakdown.

No account is required, and the check runs once rather than tracking changes over time; for continuous monitoring, HubSpot points users to its separate paid AEO product. The Grader works for any brand, including competitors, making it useful for a quick benchmark rather than ongoing measurement. No pricing applies since the report itself is free.

• Free brand check across AI engines
• Sentiment analysis from AI training data
• Brand recognition and presence scoring
• Share of Voice against competitors
• No account required

What is Relixir?

Relixir sells "Rex," an autonomous agent that connects to a company's CMS, analytics, CRM, and Slack to run AI-search-visibility monitoring, generate and publish GEO-optimized content with JSON-LD schema, refresh existing content on a 30-60 day cycle, and run backlink outreach aimed at domain authority. It also includes technical site-health audits and tracks competitors' AI visibility and citation patterns across ChatGPT, Perplexity, Claude, and Google AI Overviews.

The service is "forward-deployed": Relixir's own team configures and manages Rex for the client rather than offering self-serve access, and pricing is custom, quoted through a demo call. The homepage also publishes benchmark comparisons against named frontier AI models with specific accuracy, speed, and cost figures; these are vendor-supplied claims that could not be verified from the source text and should be treated as marketing data, not audited results.

• Autonomous GEO workflows running 24/7
• AI visibility monitoring and citation optimization
• Autonomous content generation with schema
• 30-60 day content refresh cycles
• Domain authority building automation
