You leave withA first screen or clickable prototype for your main user journey, notes from one peer test, and a review of what works, what is simulated and what still needs building
Safety tipUse made-up sample data in your prototype. Never put real names, emails or client details in it

Where you are

You have a brief and an architecture. Now you build something people can see and click. It is a prototype: it looks and feels like the product, but much of it is simulated. That is fine. Its job is to make your idea concrete enough to test and discuss.

What you will make

One screen, or a few linked screens, for the main user journey: the one task your product exists to help with. You build it in the assistant's canvas or preview, improve it twice, watch a partner try it, and then review it honestly.

For TutorDesk, the main journey is a parent booking a lesson: open the tutor's page, see free slots this week, pick one, enter a first name and email, and see a confirmation. In the prototype nothing is saved and no email is sent: those parts are simulated.
