Send 1 to 100 AI testers to your site. Each one is a different synthetic user with their own age, job, country and device. They tell you what they think you offer, where they got stuck, whether they'd come back and what they'd pay, in any language. Every run also comes with a QA report: 35 automated checks and a bug list from six expert AI testers.
No sign-up for the first 3 testers. Want testers from a specific country, or answers in another language? Open the options under the slider.
AI testers are synthetic users: they read your pages' text, not a real browser, and they aren't real people. They're great for catching obvious problems fast. For real reactions, or a phone app, use human testers.
Exepal's MCP server has a strangers_ai tool: 10 AI testers per call for $1, paid per call in USDC (x402) or from your key's credit. Call it again with offset for 10 more, as many times as you like.

In their own words, with a 1-5 first-impression score. If people can't tell what you do in seconds, you'll see it here.
The exact headline, button or missing piece that confused them or made them leave.
A 1-5 come-back score and a yes, maybe or no on paying, so you can see who your page is really working for.
"7 of 10 couldn't find the sign-up button." The issues more than one tester hit, most common first.
The single change that would help the most testers, plus a two-sentence verdict on how your site lands.
Add up to 5 questions, like "Would you sign up?" or "What would you pay?", and every tester answers in character.
While the testers read your site, a QA pass checks it the way a test team would. AI QA tools usually cost $49 a month per seat, or $1,000 a month per app for a hosted service. Here it comes free with every run, with no subscription.
Accessibility (alt text, labels, page language, zoom, headings), SEO (title, description, canonical, share preview), security headers, mixed content, speed and mobile, with a 0-100 score for each area.
Six AI specialists in UX, accessibility, security and privacy, conversion, mobile and localization report real bugs, each with severity, where, steps, expected, actual and a fix.
Up to 20 links on your page are opened, and anything returning an error is listed.
Each failed check and every bug comes with the change to make, ready to hand to your developer or your coding agent.
Leave the country empty for a global mix of testers from 20+ countries, or pick a market: your testers become locals and judge your prices, wording and trust signals the way people there would. Launching in a new country? Test your localized site before you spend on ads.
Check that strangers get your offer before you buy traffic.
Find out if the price is clear, believable and worth it to your audience.
Run the same testers on two versions and compare the scores.
Test your localized pages with testers who live in that market.
Add a quick user-testing section to every client audit for a few dollars.
Let your coding or marketing agent check its own pages through MCP before it ships them.
Use AI testers to catch the obvious problems in minutes on every page, then real people to confirm.
