What is AI user testing, and how does Menso run it?
AI user testing sends an AI agent with a persona and a task through your real website, to see whether a person like that would finish and where they would get stuck. Menso runs the agent in a cloud browser on your live site. It looks at each screen, clicks, types and thinks aloud until it finishes, gets blocked or runs out of steps. You get a replay of every step, with what it was thinking, a TRACES score out of 100 and a report with a fix prompt for each friction point. A free account gets 3 tests a month. It does not replace real users.

What happens in a Menso test
You give it an address and a task. Paste your product's URL and pick a template: Purchase intent, Sign up & log in, or With materials. Or start from the address alone, and Menso researches the product and writes a persona and a task for it first; that research does not use a test.
An AI user works through the task. It gets its own browser session on your live site. At each step it looks at the screen, decides what to do, acts, and says what it expected and what happened. It can sign up or log in with an email and password you give it. Saved logins are stored on Menso's server and used by Menso's cloud browser to run the tests you ask for. The web app shows a saved login's email or username, never its password.
The run ends at a result. It stops when the task is done, when the product blocks it, or when its step budget runs out (the Product Hunt board run below had 16 steps). If a run is interrupted on Menso's side, the test stays held for one free retry: a retry that finishes counts once, and an unused or interrupted retry gives the test back.
You read the evidence. The replay shows every step with the AI user's think-aloud. The TRACES score sums the run up in six dimensions, each with a written reason.
What you get back
A replay of every step: what the AI user saw, did and thought. Every plan.
A TRACES score from 0 to 100 across six dimensions, each with its reason. Every plan. How the score works.
A share link for a replay, for your team or a client, once Menso has checked that it shows none of your logins or secrets. Pro and Max.
A UX report on every run, with a fix prompt per friction point for your AI coding tool. Free shows the first 3 friction points on screen; Pro and Max show all of them and export a PDF.
How deep does a test go?
Every test now runs at the Deep setting: the AI user gets time to think at each step, the same setting every run on the Product Hunt board used. There is no cheaper, shallower tier to pick; one test is one test.
What it costs
Pro: 12 tests a month for $29, about $2.42 a test; Free: 3 tests a month, no card.
Free: 3 tests a month, there from signup; unused tests reset. A one-time Welcome pass in the sidebar adds 3 more that do not expire.
Pro: $29 a month for 12 tests, plus replay sharing and two products at once.
Max: $69 a month for 30 tests, six products at once and the front of the queue.
Extra tests on any plan, Free included: 5 for $15; they do not expire with the month.
Menso puts the top launches from Product Hunt's weekly board through one shared task. Here is one of them; the full board has the rest of its week.
Every run here used Menso's Purchase intent template: the persona Zainab Salazar, a freelance UX consultant, reads the homepage, the pricing page and the FAQ, decides whether she would buy or sign up, and stops before paying. It is a route-specific diagnostic, not a product-wide score.

TRACES 83.5/100
Product Hunt week 38 (Sep 14 – 20, 2026), #2 on Product Hunt's board · tested Sep 21, 2026 · one AI user, one run (n=1) · Deep test · 16 of 16 steps · tiun.io
Zainab scrolled the homepage for five steps without finding a pricing link, and at step 6 typed the pricing address herself. At step 8 she reached the Free vs Enterprise table, then read the help centre and the docs FAQ, and at step 16 decided to sign up for the free tier.
T 4 · R 4.5 · A 4 · C 4 · E 4.5 · S 4 (each out of 5)
Review note: The actor never opened the top-right menu, where Pricing sits; this is not a claim that the site has no pricing link.

Who Menso is for, and who it is not for
A good fit
Your small team is about to ship, or has just changed its signup or purchase path.
You want an AI user to try it first, before real visitors arrive.
You cannot pay for a panel of human testers yet and want to decide where research with people should go first.
Not a fit
You need to understand how customers feel or whether they trust you.
You need a rate across many visitors, or scripted tests that pass the same way after every deploy.
You need phone layouts or native apps checked.
You need an accessibility audit or a security test.
You need verification codes and CAPTCHAs handled without your help.
What it cannot tell you
One AI user, one route, one run. The result describes that route, not your whole product, and a different persona or task can go differently.
An AI user is not your customer. It has no money at stake and no history with your product. Studies of AI-simulated users in conversation tasks report that they can miss friction people feel and make results look more optimistic (Liu et al., Yoon et al.).
It has no inbox or phone of its own. When Menso recognizes a signup or login page asking for a verification code, sent by email or by SMS, the run pauses and asks you to paste the code (or the emailed link), and waits up to two hours; if nobody answers, the run ends there. If it does not recognize the page, the AI user decides on its own what to do. A CAPTCHA that Menso recognizes also pauses the run. You can skip the step or stop the test, and the run ends after ten minutes if you do neither.
It is not an accessibility audit. The board run cited on this page used no keyboard navigation and no screen reader.
Use it to find likely friction before real users arrive, and to decide where your research with people should go next.
Is AI user testing the same as synthetic user research?
Not quite. Synthetic research tools ask an AI persona interview questions and read its answers. An AI user test puts the persona in front of your actual product and records what it does. Menso does the second. Both are simulations, and neither replaces talking to your customers. The comparison of AI usability testing tools sets out the difference, and the guide to AI that uses your website like a real user covers the tools that operate a live site.
How do I know the AI user behaves like a real visitor?
You check it, one finding at a time, and treat each run as a lead. The replay shows what the AI user saw, did and thought at every step, so you can drop a step that looks unlike a person before acting on it. Then look for the same moment in real traffic: your analytics or server logs show whether visitors request the page or address the AI user tried, and session recordings show whether people stop where it stopped. When you can, watch a few people do the same task. If the run and your data disagree, go with the data.
Can I run a usability test without recruiting participants?
Yes. That is what an AI user test is for: no panel, no scheduling, no incentives. You get a stranger's first pass through your flow in one run. You do not get a real person's motives or stakes, so use the result to decide where to look, then confirm the findings that matter with people. Other ways to check usability with no one to recruit are in the guide to testing without participants.
Does Menso need my code or a tracking snippet?
No. The AI user visits your live site the way a visitor does, in its own browser session. For pages behind a login, give it an email and password on the credentials card. It signs in with email and password only; Google sign-in on your product is not supported yet. Menso Studio, a Mac desktop edition, tests builds that are not live yet, in your development environment. It is open to company teams only: write to support@menso.io. This page describes the web app.
How much does AI user testing cost with Menso?
Pro: 12 tests a month for $29, about $2.42 a test; Free: 3 tests a month, no card. See pricing for every plan.
Can I share a result with my team or a client?
On Pro and Max, you can make a share link for a replay. It opens without signing in, like the Product Hunt board replay on this page. Menso first checks the replay for the logins and secrets you gave it, and makes no link if it finds one or cannot run the check. Every plan gets a UX report on every run. On Free you read it on screen, with the first 3 friction points and their fix prompts; Pro and Max see every friction point and can export the report as a PDF.
