Can I just ask ChatGPT what it thinks of my brand?

Yes — and you should, today. But treat one answer as an anecdote, not a finding. Engines vary run to run, your logged-in session is personalized, and a single prompt covers one question of the dozens buyers actually ask. A real check uses many prompts, repeated runs, and a clean environment.

Which AI is best for checking brand sentiment?

Check the engines your buyers use, not the one that flatters you. In practice that means ChatGPT and Perplexity first, then Gemini and Claude. They behave differently: in our June 2026 runs, ChatGPT often answered from memory with no citations, while Perplexity cited sources on every single run.

How often should I re-check?

Monthly, with the same prompt set, so changes are comparable. Engines update continuously; a check older than a quarter describes an engine that no longer exists.

How do you check what AI says about your brand?

TL;DR: there are two ways. The manual method is free and takes 20 minutes: ask the engines your buyers' questions and read the answers. It is worth doing today — and it has three blind spots that make it unreliable as a measurement. The measurement method fixes them: many prompts, repeated runs, clean sessions, and scoring against competitors. Use the first to get alarmed, the second to get answers.

What is the manual method?

Open ChatGPT and Perplexity. Ask the questions a buyer would ask: "best [your category] for [your buyer]", "[your brand] vs [competitor]", "is [your brand] worth it", "[competitor] alternatives". Read what comes back. Note who gets named, who gets recommended, and what the engines claim about you. Twenty minutes of this is more honest than most brand decks.

Two hygiene rules while you do it: use a private window or an account that hasn't researched your own brand, so personalization doesn't flatter you. And copy answers out verbatim with the date — engine answers change, and an undated screenshot proves nothing in next month's argument.

Where does the manual method mislead you?

Personalization. Your logged-in session knows you. It may name your brand because you keep asking about it. Your buyers' sessions won't.
Single runs. Engines vary between runs on the same question. In our June 2026 testing we ran every prompt three times because one-run results kept disagreeing with themselves.
Coverage. You'll ask five questions. Buyers ask across the whole funnel — comparison, validation, problem, alternatives. The question you skip is often the one you lose.

Which questions should you actually ask?

Cover the four families buyers use. Swap in your own category and rivals:

Comparison: "best [category] for [your buyer type]" · "top [category] tools in 2026"
Validation: "is [your brand] worth it" · "[your brand] reviews — what do customers say"
Problem: "how do I solve [the problem you fix]" — does the answer route to your category at all?
Alternatives: "[competitor] alternatives" · "[your brand] vs [competitor]"

Record three things per answer: who got named, who got recommended, and any factual claim about you — price, products, ownership. A plain spreadsheet beats memory: one row per question, one column per engine, dated.

What does a real measurement look like?

Four properties, none optional: enough prompts to matter (50+, mapped to funnel stages), more than one engine, repeated runs with variance reported, and competitor benchmarking — your score means nothing without share-of-voice context. Score every answer against a fixed rubric: mentioned, cited, recommended, or invisible. That's the entire published methodology; demand the same from anyone you hire.

What should you do with the results?

Three outcomes, three moves. Invisible: diagnose why — start with the five checkable causes. Mentioned but misdescribed: hunt the stale sources the engines repeat, fix them at the origin. Visible and accurate: defend it — re-measure monthly, because engines change weekly and competitors are working on the same answers.

What's the fastest way to start?

The free snapshot: 10 buying-intent prompts across ChatGPT and Perplexity, your mention rate vs your closest competitors, in your inbox within 2 business days. The full audit is the measurement-grade version — 50–150 prompts, 4 engines, 3 runs each, with the report to show for it.
