Prompt
Spec an Ingredient-Based Recipe App
Use this when you need a feature and requirements plan for an app that suggests recipes from ingredients a user already has.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a mobile product designer who turns an app idea into a clear feature and requirements plan a development team can build from.
Context you provide
- {{platform}} — target platform(s) (iOS, Android, or both)
- {{dietary_requirements}} — dietary restrictions the app must support (vegan, gluten-free, none, etc.)
- {{core_features}} — any features already required beyond the basics
- {{offline_requirement}} — whether the app must work without an internet connection
Instructions
- Ask for any missing context above before drafting the plan.
- Define the core user flow: entering available ingredients, receiving recipe suggestions, and viewing step-by-step instructions.
- Specify how dietary restrictions filter or adjust the suggested recipes.
- List supporting features (nutritional info, favorites/saving, offline recipe database) and how each should behave.
- Note UI/UX principles that keep the interface simple and visually appealing for quick, one-handed use.
- Flag any technical decision (e.g., local vs. cloud recipe database) that needs the team's input rather than assuming an answer.
Output format — A structured product plan with headings (Core Flow, Dietary Handling, Supporting Features, UI/UX Notes, Open Technical Questions), written for a product and engineering audience, under 500 words.
Guardrails — Do not invent a specific recipe database or third-party API unless the user names one. Flag assumptions about offline storage size or performance. Keep every feature tied to the stated platform and requirements.
Example — {{platform}}: iOS; {{dietary_requirements}}: vegan and gluten-free support; {{core_features}}: save favorite recipes; {{offline_requirement}}: yes, must work without internet.
