AI usability testing: simulated visitors on your live site

The team that built a flow cannot see it fresh. Usability sessions with real people show where newcomers struggle, but they take days to recruit and schedule, so most flows ship before anyone outside the team has tried them. Analytics shows the drop off only after real visitors hit it. A run in Mimiq sends simulated visitors through first, so the obvious breaks and dead ends are fixed before anyone real meets them.

• Real browsers and a task in plain words: they click, scroll, type, fill in forms, go back, wait, and check their email.
• Each visitor acts as one of your target customers and decides every step from what is on its screen.
• See what each one did, step by step, where it left, and why, in its own words.
• Fix it, then send the same visitors through again with the same task.

At every step, each visitor looks at its screen and decides what to do next: click, scroll, type, fill in a form, go back, wait, check its email, or leave. Nobody scripts the path. They get lost where a newcomer might, and they say what they were thinking at each step.

When a form asks for details, they use their own, which are made up, since they are simulated: a name, an email address on a Mimiq domain with a working inbox, and a password Mimiq sets for them. So a verification code or a confirmation link reaches them, and they can carry on.

A session ends when a visitor says it is done, leaves, or gets blocked by the site. It counts as finished only when its own last steps show the task done, not because it says so.

The problems a newcomer hits and an insider never sees: an error on screen, a button that does nothing, a label that means something else to an outsider, an error message that does not say what to fix, a form that will not accept what people type, a required step with no reason given, or a price that appears only after the account is made.

Every click and form entry is recorded with what it did: moved the visitor on, changed nothing on screen, or failed. So a dead button stands out in the step by step view, next to what the visitor said about it.

An end to end test follows a script and checks that the flow works. It passes as long as the button does what the code says, even when no newcomer would find the button. A Mimiq run checks whether someone who has never seen the site gets through, which is a different question, so most teams want both.

Session replay and funnel analytics show what real visitors already did, after launch. A run happens before anyone real arrives, and each visitor explains its choices in words. Once you have traffic, your analytics are the better evidence for what is happening.

Every visitor in a Mimiq report is simulated. They find what breaks and what confuses. They do not predict how many real people will convert. A run shows where visitors like yours get stuck or hit something broken. For how many people finish, or which version converts better, ship and measure.

Treat a clean run as meaning nothing obvious was broken for those visitors, not as proof that the flow works for everyone.

They cannot pay: Mimiq gives them no payment details. A CAPTCHA or bot check can stop them. Any visitor stopped by one is marked as blocked by the site, and if it stops every visitor, the run fails and nothing is charged. A staging or preview address without bot protection works, as long as it is public or you give access.

With paid credits, visitors can sign in with a test account you give them and open protected previews (a Vercel bypass secret or a site password). The secrets are filled in only in the browser and deleted when the run ends. Test accounts and protected previews come with paid credits: the $9 Starter or a plan from $19 a month.

Keep the task to one path, such as a signup and the first screens after it, with no long setup. A run usually takes a few minutes, more when runs queue for capacity, and uses 5 credits a visitor.

They really submit your forms, so each visitor that signs up leaves a test account, and on a store they can leave abandoned carts. Use a staging site if that matters.
