About this app
Bulking meals planned around your exact macros, built by the AI you already use instead of ours. So there's no subscription. Pick the foods you like, paste one prompt into ChatGPT or Claude, and import a full week of meals, macros and a shopping list.
Bulking is simple: eat big, hit your protein, train hard. Doing it consistently is the hard part. JSON.fit makes eating enough easy.
WHAT YOU GET
- Bulking meals with exact ingredients and every cooking step
- AI meal plans dialled to your goal, bodyweight and macros
- Pick the foods you like, with a deep rotation so you never get bored
- Smart shopping lists, priced and sorted
- A meal prep guide that tells you what to cook first
- Macro and calorie tracking, built around your plan
- Training programs that run a full year, fully tracked
- Works with ChatGPT, Claude, Gemini, DeepSeek and more
WHY IT'S DIFFERENT
Most fitness apps run AI on their own servers and charge you $10 to $20 a month for it. JSON.fit uses the AI you already use, so there's no cost to pass on, and you're never locked into one provider.
No subscription. No ads. No catch.
YOUR DATA STAYS YOURS
No accounts. Your nutrition and workout data never leaves your device. The app collects only anonymous, non-personal usage stats to help improve it.
Built for skinny guys who struggle to eat enough, and for anyone who wants a real plan without the monthly fee.
