A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

Recreated prompt

The source didn't share its exact prompt, so we wrote one from what it describes. The result shown is the source's, not ours.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

I want to build a mobile app that makes a fresh bedtime story every night, narrates it in a warm voice and makes the child the hero. It should be audio only, with no screen time. Help me build it step by step in React Native with a Supabase backend, and get it ready to submit to the App Store.

Try this in:

ChatGPT Gemini Grok Claude

Sends the Recreated prompt shown above. ChatGPT and Grok open with it filled in, and ChatGPT may send it straight away. Gemini and Claude open empty, so we copy the prompt for you to paste. Every button also copies it.

The source used Claude Code, which can take actions on your computer or in a browser. These are general chat tools, so results may differ, and a normal chat may only give you a plan.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Help me build and ship a small mobile app by describing what I want, one working piece at a time.

Questions to ask me first:
- What problem does the app solve, and for whom?
- What's the smallest version worth releasing?
- Which platforms, and do you have developer accounts?

Inputs (fill in or confirm):
- App idea and users: [IDEA / USERS]
- Must-have features for version 1: [FEATURES]
- Tech choices, if any: [e.g., REACT NATIVE / SUPABASE]
- Accounts I have: [APPLE / GOOGLE / HOSTING]

Rules:
- Plan the smallest releasable version first and list what's out of scope.
- Build one feature at a time and tell me exactly how to run and test it.
- Keep API keys out of the app code and explain where secrets go.
- For apps for kids, follow the app store's kids and privacy rules and collect as little data as possible.

Checkpoint: After the plan, wait for my approval before writing code.

If you get stuck: When something breaks, ask me for the exact error and fix one thing at a time.

Verify before you finish: Before submission, walk me through a checklist: privacy policy, store rules, test on a real device.

Output: A step-by-step build plan, working code per step and a submission checklist.

Done when: The app runs on my phone and is ready to submit.

Outcome

Robin Singhvi watched friends come home exhausted while their kids demanded a new bedtime story every night, which often ended with an iPad and screen-time guilt. Singhvi wanted an app that generated a fresh audio story each night, narrated it warmly and made the child the hero, with no screen. Working on weekends, Singhvi built Gramms (short for Grandma) with Claude Code, including a React Native front end, a Supabase and Railway back end, the AI story pipeline and the App Store submission, by describing what was wanted and iterating. Singhvi says zero lines of code were written from scratch, and the app is now on the App Store.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.
