What you get back. What broke, who it happened to, what they said, and what to fix first.

Each square is one step: a click, a scroll, a field filled in. A taller mark is a new page or screen. Those who finished took 5 to 9 steps.

Top issueURL field validation rejects valid URLs without clear error guidance5 of 5 raised it

Suggested fixFix the URL validation logic to accept standard URL formats (with and without https://, with and without www). Add specific error messaging that shows an example of the expected format (e.g., 'Please enter a valid URL like https://example.com or example.com'). Ensure the field clears properly when users retype.

The Tallyloop sign-up from the top of the page: five simulated people, each step as the flow recorded it. What anyone typed is never kept.

What it tests. Anything a customer will see, shown the way they would really meet it.

How far to trust it. Mimiq measures that in public, and says where it is not there yet.

76%Mimiq's forecast picked the headline more real readers clicked, on 1,000 A/B tests held out from its development.

On 1,000 held-out headline A/B tests: Mimiq's forecast 75.7%, Best rule of thumb (the headline written first) 61.3%, Asking an AI directly 53.1%, A coin 50.0%.

Accuracy with its 95% interval, on the same 1,000 tests. Ranking emails, ads and page versions is not there yet; it is the work in progress. The benchmark
  • Pre-registered. Each benchmark's plan is public before it runs, and its result after, whichever way it goes.
  • Always labelled simulated. Simulated people are a fast first pass before real research, not a replacement for it.
  • What they type is not kept. A flow records each step in words. The values typed into your site are never stored.
  • Payments through Stripe. Card numbers never touch Mimiq's servers. Trust and data

From your coding agent. Your agent built the page; let it show it to a crowd before you review the diff.

150 credits$96 page tests of 25, or 5 people in flows
500 credits$2920 page tests of 25, or 16 people in flows

5,000 credits$199200 page tests of 25, or 166 people in flows

One credit is one person in a page, ad, email or copy test; a person in a flow uses 30, since each gets a real browser for minutes. Packs are one-time and never expire. Full pricing

Questions.

No. Every person in Mimiq is simulated: a profile drawn from population statistics (age, work, place, habits) and played by an AI. They are fast, cheap and candid, and they are not your customers. Use them to find problems before real people do.

You give a URL and a task, like signing up for the free trial. Each person opens the site in their own real browser and clicks, scrolls and types for up to 15 steps, saying what they think at each one. You see how far each got, where they stopped and why. A flow costs 30 credits a person.

It depends on what you test. On headlines, Mimiq's pre-registered forecast picked the real winner 76% of the time on 1,000 held-out tests. Ranking emails, ads and page versions is not there yet, and a flow shows where people get stuck rather than predicting your conversion rate.

No. A flow keeps each step in words (clicked this button, filled in two fields), never the values typed and never an address's query string.

No. People in a flow cannot sign in to an existing account, so they stop at a login page. Test the public part: the landing page, sign-up, pricing and checkout.

Your first test is free: sign in with Google and it starts right away. A free account includes 100 people, no card. Then one-time packs from $9 for 150 credits, which never expire. A person in a page, ad or copy test is one credit; a person in a flow is 30.
