AI Answer Checker

Test how ChatGPT, Claude, Gemini, Perplexity, Grok, and DeepSeek answer your brand-relevant queries. Standardised prompts, 6-engine grid, CSV export.

Step 1

Set up your test

Brand name + a query you want to rank for in AI answers.

We'll generate 4 prompt variants for you to test across all 6 AI engines.

Step 2

Test prompts (copy → run in each engine)

Open each AI, paste the prompt, then come back and record what you saw. Test all 4 variants per engine for solid signal.

Direct ask

your topic

Best-for variant

What's the best your topic? Give me 3 specific recommendations.

Comparison probe

Which is the best option for your topic and why?

Source request

Who are the most cited brands for your topic? Include URLs.

Step 3

Record results

Add a query above to start tracking. Each query gets a 6-engine row where you record whether each AI cited, mentioned, or skipped your brand.

How to test like a pro

Three-step workflow that yields signal-rich results.

Pick the right queries

Use queries with real commercial intent. 'Best CRM for small business' beats 'CRM software'. The AEO Query Generator produces 30-50 of these per topic.

Run all 4 prompt angles

Same query asked 4 different ways. AI answers vary with phrasing — running variants reduces false negatives and surfaces edge cases.

Note the sources cited

Even when an AI doesn't cite you, note which sources it does cite — Wikipedia, Reddit, G2. Those are where you need to show up.

Frequently asked questions

Why can't this query the AIs for me?
Each AI engine charges per query and most don't allow third-party tools to call them on behalf of users without an API key. We could build it with a backend + your API keys, but that's a paid product. This tool gives you the same workflow — standardised prompts, 6-engine tracking, CSV export — without the cost.
Why 4 prompts per query?
Different prompt phrasings produce different answers. A 'direct ask' might miss you; a 'best for X' might cite you. Testing all 4 gives you a fair signal across phrasing variants and reduces false negatives. It's the same approach the full FixAEO scan uses.
What's the difference between Cited and Mentioned?
Cited = the AI included a hyperlink to your URL in its answer. Mentioned = it named your brand but didn't link out. Both count as wins, but Cited is stronger because it drives traffic. Track both separately.
Does my data save?
Yes — your queries, results, and notes save to your browser's localStorage. Close the tab, come back tomorrow, everything's still there. Nothing leaves your browser. Export to CSV for backup.
Is this different from the FixAEO audit?
Yes — the audit programmatically queries the engines for you (via our backend + API keys) and scores results across 10 signals. This tool is manual but free. Use the Answer Checker for ad-hoc testing; use the audit for repeatable benchmarks across a full topic set.
