HubSpot AI Search Grader review: pricing, features & alternatives

Enter your brand and the grader runs test queries across ChatGPT, Perplexity, and Gemini, returning a 0–100 score across five dimensions — sentiment (weighted up to 40 points), presence quality, brand recognition, share of voice, and market position — with a written interpretation. No account, no run cap, no cost. As an executive conversation-starter about AI visibility, it's the lowest-friction artifact in the category.

In 2026 it rebranded to 'AEO Grader' (the old URL redirects), part of HubSpot's push into answer-engine optimization after acquiring Xfunnel.

Three structural issues cap its usefulness. Run-to-run variance: LLM outputs are stochastic, so your score changes on repeat runs — HubSpot's own disclaimer says results are not guaranteed. Mixed clocks: the engines carry different knowledge cutoffs (one GPT variant at Aug 2025, Gemini at Jan 2025, Perplexity live), so the sub-scores describe different moments in time, averaged as if they didn't. And the mention counts appear aggregated from indexed content rather than real query volume — the methodology is unpublished.

The paid path deserves its own caution: HubSpot AEO ($50/mo, 25 prompts, 28-day trial) is closed-loop — it sees only the prompts you load — and in one documented test reported 0% AI visibility for a domain that Semrush and Ahrefs simultaneously showed with real, healthy AI presence. Auto-generated competitor and persona setups also tested unreliable, needing manual correction.

Everyone, once — it's free, instant, and the written readout is a decent executive artifact for starting the GEO conversation.

Nobody should track progress with it: run-to-run variance makes deltas meaningless, and the $50 upsell is weaker than dedicated trackers at the same price. Get your snapshot, then graduate.

Every row below is a capability we already listed for HubSpot AI Search Grader. It is the published feature set for this page, not a guess at an unpublished demo. Compare it with the Promptwatch checklist that follows.

On this listing, HubSpot AI Search Grader is a Free checker for Anyone wanting a zero-cost first snapshot of AI visibility — as a conversation starter, never as measurement.. What we sourced here: Instant AI visibility score; Brand sentiment snapshot; Share-of-voice estimate; Shareable report.

If you buy HubSpot AI Search Grader for the job above, plan a second tool (or Promptwatch) for the layers this listing does not document. Still missing here: AI crawler logs (Agent Analytics), crawl-to-citation path, bot errors; Visitor analytics: AI-referred sessions and conversions; Content Agents that plan, write, and publish GEO pages to a CMS with a review inbox; Citation analytics at page, domain, Reddit, YouTube, and offsite level; Prompt volumes, difficulty, query fan-outs, personas, city-level geo; Prompt and citation trends (what changed between checks); ChatGPT Shopping tracking and Ads Radar; Agent Chat, Unified Actions, MCP server / REST API on paid plans. Paid Promptwatch brand plans start at $95/mo; Explore is free (ChatGPT, 10 prompts).

HubSpot AI Search Grader is a snapshot or grader, not a daily operations platform. Promptwatch is the paid measurement stack when you need history, crawler logs, visitor conversions, and content that ships from the same login.

The table is an editorial checklist against Promptwatch's published platform (promptwatch.com/llms.txt, 2026-08-23). It is not a hidden feature list for this vendor. 'Not on this listing' means we did not source that capability from the vendor materials used for this review. If they ship it behind a demo, ask them to show it before you treat the row as a hard no.
