HubSpot AI Search Grader review
Ranked #51Free instant snapshot of how AI engines see your brand — the zero-cost starting point.
Our verdict
The AEO Grader (rebranded from AI Search Grader in 2026) does exactly one thing at exactly the right price: a free, no-signup snapshot of how ChatGPT, Perplexity, and Gemini see your brand, scored out of 100. Treat it as a mirror, not a meter — scores drift between runs by design, the three engines have different knowledge cutoffs, and HubSpot's own disclaimer disclaims the results. The $50/mo AEO upsell has produced confidently wrong readings in testing; spend that on a real tracker.
Best for: Anyone wanting a zero-cost first snapshot of AI visibility — as a conversation starter, never as measurement.
HubSpot's AI Search Grader gives you a free, instant report on your brand's presence and sentiment in AI answers — no account gymnastics, just a snapshot with a shareable score.
It's the tool to run before buying anything else: if the grade surprises you, you have your business case for a real tracker.
What the free tool does
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.
Why the numbers aren't measurement
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And the mention counts appear aggregated from indexed content rather than real query volume — the methodology is unpublished.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.
| Capability | AEO Grader | Dedicated tracker |
|---|---|---|
| Cost | Free | $20–200+/mo |
| Engines | 3 | 5–17+ |
| History & trends | None | Daily/weekly series |
| Custom prompts | No | Yes |
| Score stability | Varies per run | Sampled & averaged |
Who should use it
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.

Frequently asked questions
Why does my score change every time I run it?
LLM outputs are stochastic and the grader takes single samples — HubSpot's own disclaimer says results aren't guaranteed. Differences between runs are mostly noise, which is why it can't measure progress.
Which engines does it actually check?
ChatGPT, Perplexity, and Gemini only — no Claude, Copilot, Grok, AI Overviews, or AI Mode. And the engines carry different knowledge cutoffs, so the sub-scores describe different points in time.
Is the $50/mo HubSpot AEO worth it?
Rarely as a primary tool: it tracks only ~25 loaded prompts, and one test showed it reporting 0% visibility for a domain other platforms showed with healthy AI presence. At $50–100, dedicated trackers offer far more.
