A few things worth knowing

Is simulated message testing a replacement for real audience research?

No. Cairo produces simulated signals that help you compare directions and prioritize what to validate with real people. It does not replace surveys, interviews or live campaign data.

What kinds of messages can I test with Cairo?

Headlines, value propositions, ad copy, email subject lines, calls to action and positioning statements. If an audience can read it or experience it on a page, Cairo can simulate reactions to it.

Can I test messages in context, on a real page?

Yes. Paste a URL and Cairo simulates how visitors read the message in its real context—surrounded by your design, offer and navigation—not in isolation.

How much does message testing with Cairo cost?

Free includes 500 welcome credits. Pro includes 10,000 credits for $29 per month; Agency includes 50,000 for $99 per month. Costs depend on the pages, interactions and variations involved. Failed actions are refunded.
