How It Works

Built for the moment a recipe goes sideways.

🔄

1. Swap

Type or say what you ran out of. Get ranked substitutes with exact ratios scaled to your amounts, and what each swap does to texture, rise, and flavor.

⚖️

2. Convert

Cups to grams knows that a cup of flour isn't a cup of sugar. Temperatures, volumes, weights, servings — instant and offline.

👨‍🍳

3. Invent

Tell the Novelty Chef what's in your kitchen and who's eating. It invents a catchy new recipe — grounded in taste science, scored for taste and health, read aloud step by step.

Privacy First

No account. No ads. No tracking. The converter and substitution library never touch the network, the on-device AI runs entirely on your iPhone, and optional cloud answers are processed with zero data retention — never stored, never used for training. Read the full privacy policy.
