The App Builder Report

AI app prompt builder

Fill this in and get a fully specified prompt you can paste into any AI app builder. Takes about 60 seconds.

Why this matters: vague prompts are the single largest cause of wasted credits. Every major AI app builder charges the same for a prompt it misunderstands as one it gets right — so four attempts at one screen costs four times, for three results you did not want. Specifying properly up front is the cheapest optimisation available.

Your app

Who uses it and what they do with it. "A booking app for a hair salon so clients can book appointments with a specific stylist."

Platforms
Screens

Name each screen and what it shows. Naming screens explicitly is the highest-value thing in this whole form.

The things and their fields. "Appointments have a client name, phone, service, stylist, date and time."

Features

The logic that makes it yours. This is the part AI builders get wrong most often, so spell it out.

    How to not waste credits

    Every major AI app builder meters you, and none of them refund a misunderstanding. These are the habits that make the biggest difference.

    Do thisInstead ofWhy
    Name every screen and what it shows"Build a booking app"Unnamed screens get invented, then rebuilt
    State the data model explicitlyLetting it infer the fieldsWrong fields mean rebuilding everything downstream
    Spell out the rulesAssuming it knows your businessBusiness logic is where these tools fail hardest
    Batch related changes into one messageThree separate small requestsMost tools charge per prompt, not per unit of work
    Fix the biggest thing firstPolishing before the structure is rightStructural changes discard the polish anyway

    Per-message pricing punishes iteration hardest — a one-word fix costs what a whole feature costs. Current figures on the price tracker.
