Meal Builder

The company appears to be a solo-developer project named Meal Builder, an app that suggests recipes based on ingredients users have at home. The author states it was built for the OpenAI 2026 hackathon and uses AI (via ChatGPT/Codex) to generate personalized recipes from pantry data.

What changed: The project is described as a hackathon submission, not a commercial product or service in production. It has no evidence of revenue, customers, or adoption beyond its own self-description.

The single most important open question: Is this a prototype with potential for further development, or a one-off experiment with no commercial traction?

• The description states Meal Builder is an app that suggests recipes based on what a user has in their kitchen.
• It tracks foods and quantities in the user’s pantry or refrigerator.
• AI (via ChatGPT/Codex) recommends personalized recipes based on ingredients, desired portions, meal type, nutrition goals, dietary preferences, and preparation time.

1. Is this project intended to become a commercial product, or is it a one-off experiment?
2. What is the plan for scaling beyond the current prototype and hackathon version?
3. How does the app handle data privacy and user security in its current form?
4. Are there any plans to monetize the app or generate revenue?
5. Has the app been tested with real users, or is it still in development?
