Try the Nutrition Playground, no signup needed

For a while, the only way to see what Eat My Words actually does was to make an account. That always felt backwards to me. If the magic trick is “tell the AI what you ate and it figures out the nutrition,” you should get to see the magic trick first.

So the Playground is now live on the marketing site. Open it, type something like “two scrambled eggs and a slice of sourdough toast with butter,” and you'll get a nutrition card back. Calories, protein, carbs, fat, the works. No account, no email, nothing.

The Playground runs through the same prompt and the same models the real app uses, so what you see is honestly what you get once you sign up. I wired it up to support a handful of OpenAI models too, including GPT-5-mini and GPT-4.1-mini, so I can swap models without rewriting anything. That part was mostly for me, but it means the Playground stays current as the cheap fast models keep getting better.

It's still very much a try-it-and-see thing. The point is to give you a feel for the conversation, not to be a complete tool. If you want to start a real log with history and trends, that part still lives on the signed-in side.

Try it out and let me know what breaks.
