# Track calories in ChatGPT with Splot Tell ChatGPT what you ate. Splot saves every meal with its calories and macros, so ChatGPT can keep your totals, plan around your targets and look back over weeks. ChatGPT is great at estimating a meal. It just doesn’t keep the record. Splot does. ## How it works ### Log what you ate You tell ChatGPT what you ate. Splot keeps it in your journal. > **You:** Latte and overnight oats for breakfast. > > **ChatGPT** (Splot: saved breakfast): Saved both: 526 kcal and 33 g protein so far today. > > **You:** Had a chicken burrito bowl for lunch. > > **ChatGPT** (Splot: saved lunch): Saved it as an estimate: about 680 kcal and 51 g protein. You’re at 1,206 of 2,060 kcal today. In Splot: The Today screen in the Splot app. The Chicken Burrito Bowl that ChatGPT saved appears as lunch, and today’s calories go up to 1,206 of 2,060. ### Later that day: Plan around what’s left Ask for a dinner that fits the rest of your day. ChatGPT works from the totals in your journal, and the plan waits there until you’ve eaten it. > **You:** Had a chicken burrito bowl for lunch. > > **ChatGPT** (Splot: saved lunch): Saved it as an estimate: about 680 kcal and 51 g protein. You’re at 1,206 of 2,060 kcal today. > > **You:** What should I have for dinner to hit my protein? > > **ChatGPT** (Splot: planned dinner): You have 854 kcal and 38 g protein left. A chicken Caesar salad fits: about 520 kcal and 42 g protein. I’ve planned it for 19:00, and it counts once you’ve had it. In Splot: The Today screen in the Splot app, with the chicken Caesar salad that ChatGPT planned for 19:00 marked as planned. ### A few weeks in: Ask about your own weeks Every meal stays in your journal, so ChatGPT can compare your weekdays with your weekends, or find what your hardest days have in common. > **You:** Compare my weekdays with my weekends. > > **ChatGPT** (Splot: read 28 days of meals): Calories barely change: about 1,880 a day on weekdays and 1,720 at weekends. Protein is the difference. You average 118 g on weekdays but 74 g at weekends, when a late brunch replaces your usual breakfast. Last Saturday’s pancakes had 21 g. In Splot: Saturday in the Splot app: pancake brunch, a latte, cookies and beef chili, with 76 g of protein against a 122 g target.

Memory is built to remember things about you, not to keep an exact record. Splot saves every meal with its foods, portions and nutrition, so ChatGPT can add up any day or compare weeks, and you can check and correct the journal yourself. ### Who estimates the calories? ChatGPT does. Splot has no AI of its own: it saves what ChatGPT estimated, marked as an estimate, and you can change the meal afterwards. ### Which ChatGPT plans can connect Splot? Adding Splot as a custom app uses Developer mode, which needs ChatGPT Plus or Pro. Business, Enterprise and Education accounts can connect too, if their workspace allows it. ### What can ChatGPT see? ChatGPT reads your journal only through Splot, when a conversation needs it. What it receives is kept under OpenAI’s terms and your ChatGPT settings. You can disconnect it at any time, in Splot or in ChatGPT. [Privacy and control](https://splot.health/docs/mcp/privacy.md) ### Does it work in the ChatGPT app on my phone? Yes. Connect Splot once, in the ChatGPT app or on chatgpt.com, and it works in both. ### Do I need the Splot app? No. You can create your account while connecting ChatGPT, then log, plan and review meals entirely in a chat. The Splot app for iPhone and Android, coming soon, will show your journal at a glance and let you log without a chat. ### Can Claude use the same journal? Yes. Connect Claude as well, and both assistants read and write the same journal. --- Conversations shown are illustrative. Splot isn’t affiliated with OpenAI. ChatGPT is a trademark of OpenAI.
