ChatGPT, Perplexity, Gemini: how do I know if AI really understands my offer?

To know whether ChatGPT, Perplexity or Gemini understands an offer, test the category used, associated competitors, reused criteria, cited proof and recommendations produced.

To know whether ChatGPT, Perplexity or Gemini really understands your offer, do not only check whether AI cites your brand.

Check how it explains you, which competitors it compares you with, which criteria it uses, which proof it cites and when it recommends you.

AI can know your name and still misunderstand your value.

Short answer

An LLM understands a B2B offer when five elements remain coherent.

ElementControl questionGood signal
CategoryWhich family are we placed in?Precise and useful category
CompetitorsWho are we compared with?Truly comparable alternatives
CriteriaHow is the offer evaluated?Differentiating criteria reused
ProofWhat justifies the reading?Verifiable proof cited
RecommendationWhen are we selected or rejected?Correct use cases and limits

If these five elements are coherent, AI is not only citing you. It understands you in a decision logic.

Why you should test several LLMs

ChatGPT, Perplexity, Gemini or Claude do not always use the same sources, answer modes or caution thresholds. An offer can be well classified in one engine and poorly understood in another.

Engine to testWhat the test often reveals
ChatGPTPerceived category, associated competitors, generic choice criteria
PerplexityCited sources, proof reuse, dependency on specific pages
GeminiAlignment with Google results, adjacent categories, brand signals
ClaudeReasoning quality, limits, objections and risks

The right diagnosis is therefore not to ask once, “what do you think of my offer?” It is to compare several answers, across several prompt formulations, then code the gaps.

What Beyond Mentions data shows

In the first consolidated wave of the Beyond Mentions Observatory, we analyzed 4,320 Perplexity sonar answers over 3 UTC days, with 6 passes per question per day.

Observed signalVolume in the corpusReading for understanding
Source dependency4,137/4,320 (95.8%)Available sources influence explanation
Proof reuse3,714/4,320 (86.0%)Proof can stabilize the reading
Documentation and proof2,687/4,320 (62.2%)Documentation helps explain value
Criteria reuse1,464/4,320 (33.9%)Explicit criteria can be reused
Category compression1,061/4,320 (24.6%)An offer can be placed in the wrong category
Specification gap1,130/4,320 (26.2%)Requirements can be poorly formulated

The key point: AI understanding is not binary. It is measured through coherence between category, criteria, proof and recommendation.

The 6 tests to run

1. Category test

Ask:

“How would you define this offer?”

Check whether ChatGPT uses a precise category or a fallback category.

AnswerReading
Precise categoryGood signal
Category too broadCompression risk
Competitor categoryWrong-comparison risk
Vague descriptionInsufficient documentation

2. Competitor test

Ask:

“Which alternatives should be compared?”

If alternatives are too distant, ChatGPT does not yet understand the scope.

3. Criteria test

Ask:

“Which criteria should be used to choose?”

Reused criteria should reflect your real value, not only price, awareness or features.

4. Proof test

Ask:

“Which proof should be requested from this provider?”

A good signal appears when ChatGPT cites verifiable proof, not only declarations.

5. Shortlist test

Ask:

“In which case would you recommend this offer?”

The answer should connect your offer to precise buying situations.

6. Exclusion test

Ask:

“In which case should this offer not be selected?”

AI that can exclude correctly often understands better than AI that recommends too broadly.

A low score does not mean your offer is weak. It means your documentation does not yet make the right reading easy enough.

Key takeaway

ChatGPT, Perplexity or Gemini really understand your offer when they can:

  • place it in the right category;
  • compare it with the right competitors;
  • reuse the right criteria;
  • cite the right proof;
  • recommend the right use cases;
  • exclude the wrong cases.

So the question is not:

“Does AI talk about us?”

The real question is:

“Does AI prepare a decision that reflects our real value?”

FAQ

Is one prompt enough to know if an LLM understands my offer?

No. A single answer can vary. Test several questions and angles, then code recurring patterns.

What is the best signal of understanding?

The best signal is coherence between category, competitors, criteria, proof and the situations where ChatGPT, Perplexity or Gemini recommends or excludes the offer.

What should I do if AI simplifies my offer?

Publish definitions, criteria, proof, use cases, limits and rejection criteria that make the real category easier to reuse.

What is the difference between being understood and being cited?

Being cited means appearing. Being understood means being explained, compared and recommended with the right criteria.

Buyer question

What question does the buyer ask AI?

Documentation risk

Which documentation simplification can lower the standard?

Standard to impose

Which technical requirement must be clearly formulated?

Expected proof

Which evidence should be requested or published?

Rejection criterion

Which criterion excludes an insufficient answer?

Measure how AI already understands your market.
