03

Trademark basics

30 minutes
  • Search the official US trademark database (tmsearch.uspto.gov) for your name, and also search Google and the app stores for apps with the same or a similar name.
  • If a similar name already exists for similar software, pick a different name now. Changing it later is expensive.
  • Filing your own trademark is optional at the start. Many founders file once they have paying customers. This is general information, not legal advice, so talk to a trademark attorney before filing.
04

AI build kickoff

20 to 40 minutes
  • Open your AI coding tool (Claude, Cursor or Lovable) and start a new project called Allergy Card.
  • Paste the prompt below exactly as written. Let the AI finish, then run the app and click through every screen.
  • If something breaks, copy the full error message back to the AI and ask it to fix it. Repeat until it works.
  • Suggested stack: Next.js, MySQL, Tailwind, hosted on a small VPS. You can tell the AI to use it, or let it choose.
AI PROMPT 1 OF 3

Build a web app called Allergy Card. Parents sign up and add family members by first name with a list of allergens, severity (mild, severe, life threatening), and emergency steps. Show a live preview of the card.

05

Server and hosting

30 to 60 minutes
  • For the web app, the simplest path is a host that deploys straight from GitHub (for example Vercel, Render or Railway). A small VPS works too if you are comfortable with servers.
  • Set up a managed database (MySQL or Postgres) with your host and keep the password in an environment file, not in your code.
  • Put your code on GitHub so you never lose it and can deploy with one click.
AI PROMPT

My app Allergy Card is built with Next.js, MySQL, Tailwind, hosted on a small VPS. Walk me step by step through putting it online: creating accounts, environment variables, connecting my GitHub repo, connecting my domain, and turning on HTTPS. Assume I am a beginner and explain each click.

06

Backend and data

1 to 3 hours
  • Now build the core feature. Paste the prompt below into the same project so the AI keeps the context.
  • After it runs, test it with real looking data. Try it the way a customer would, including mistakes like empty fields.
  • Ask the AI to add basic checks: required fields, friendly error messages, and nobody seeing another user's data.
AI PROMPT 2 OF 3

Use an AI model to add a list of common hidden sources for each allergen and a short, polite message for restaurant staff. Offer translation into a chosen language. Render the card as a mobile friendly page and a wallet sized printable PDF.

07

Frontend and design

1 to 3 hours
  • Make it feel like a real product. First paste the design prompt, then the feature prompt below it.
  • Pick one brand color and one font and stick with them everywhere.
  • Show it to 3 people who match your customer and watch them use it without helping. Fix whatever confuses them.
