20 checks for your AI-built product, in five stations. Go through them once as if you were seeing it for the first time. Then you know where people drop off.
Open your product on your phone in a private window. Start where new people really arrive, for example via the link in your post. Do a real task, not your favourite demo. Only tick what you actually saw.

The first five seconds
Does a stranger understand what this is?
Quick testShow the first screen for five seconds to someone who doesn't know your product. Then ask: “What is this, and what would you do now?”
02/05
The way in
Does the next step deliver what the button promised?
Quick testSay out loud what you're about to see before you tap. Then tap and compare.
03/05
The first success
Can people reach the first result without you?
Quick testHand your phone to someone and say nothing. Note where they hesitate or ask you something.
04/05
When something goes wrong
Do people know what happens when it gets stuck?
Quick testGet something wrong on purpose: empty field, wrong format, network off. What do you see?
05/05
All of a piece
Does it feel thought through or just pretty?
Quick testPut three screens side by side. Do they look like the same person designed them?
What first
One broken step weighs more than ten pretty ones.
What blocks the task. Sign-up hangs, result unusable, payment unlocks nothing.
What costs trust. Hidden costs, broken promises, placeholders in the result.
What confuses. Unclear next step, too many fields, competing buttons.
What's just not pretty. Inconsistent spacing, three button styles, filler phrases.
Only ever change one thing, then run the same task again with a fresh account.

Let your agent test it.
Give an agent with browser access your URL and this prompt. It goes through the five stations for you and reports what it really saw.
Prompt
Product check from the perspective of new users
Test [YOUR URL] as if you were seeing the product for the first time. Audience: [WHO]. The home page promises: [RESULT]. Complete this real task: [TASK]. Go through five stations: the first five seconds on the home page, the way in (button and sign-up), the first success, what happens when something goes wrong, and whether the interface feels all of a piece. Use a new account and also test at phone size. For every problem: where it happens, what you expected, what actually happened, how to reproduce it. Suggest the smallest change that fixes it each time. Only report what you actually saw. If you can't reach a step, say so. Don't pay for anything and don't change anything in the live system.
