Entities and relationships spelled out
Named tables, fields and links stop the managed backend from being shaped by guesswork.

Step 1 of 5 — Vision20%
Step 1 — Your product vision
Describe Your App, Website or Landing Page Idea
Plain words are perfect — no technical language needed. Who is it for, what do they do, and what should the first version of your app or website include?
Prompt qualityNothing yet
Start with one sentence: who is it for and what do they do with it? (0 words)
Smart defaults (saves build credits)
These are AI recommendations read straight from your description — adjust them only if something looks wrong. Anything you write later in the text always wins over these switches.
Making money (is this a paid product?)
Free / internal tools skip payments entirely and stay on $0/mo free tiers.
Write a couple of sentences about your idea to unlock the next steps.
How TheMegaPrompt builds PRDs and architecture specs for Base44 apps and websites
Base44 infers tables, auth and integrations straight from your prompt. TheMegaPrompt hands it a structured PRD so those inferences match the product you actually described, whether it is an app, website or landing page.
Auth roles and visibility rules
Public, user-owned and admin-only data are separated in the spec, so access rules are generated correctly the first time.
Integration decisions made up front
Payments, email and storage are either specified or explicitly excluded, which avoids half-wired integrations.
A scoped first build
An out-of-scope list keeps the initial generation focused on the screens that matter.
How to use a structured PRD with Base44
Base44 turns prompts into full-stack apps with managed backends and instant integrations. A detailed PRD keeps the generated data models, auth flows and page layout aligned with your actual app or website.
1. Define data models before screens
Base44 infers tables and relationships from your prompt. Naming tables, columns and roles explicitly prevents the builder from guessing wrong and saves rework.
- List every entity with its fields and relationships.
- State which data is public, user-owned or admin-only.
- Specify auth roles such as admin, member or customer.
2. Lock the feature scope
A broad prompt generates extra pages and fields that break the ones you care about. Scope guardrails keep the first build small and stable.
- Include an explicit 'out of scope' list.
- Forbid placeholder content and stub components.
- Say whether payments happen in-app or offline.
3. Paste the Mega-Prompt, then iterate
Send the whole generated prompt as the first message so the architecture is correct, then request one focused change per follow-up. Small diffs are far less likely to break a working build.
- First message: the full PRD Mega-Prompt.
- Then: one screen, one flow or one bug per message.
- Re-run the generator here whenever the product direction changes.
