How to Use AI Chat

Ask about calories, macros or what to eat — in plain conversation.

AI Chat is a freeform conversation with an assistant about food, nutrition and your goals. You need to be signed in to use it — starting the tool while signed out prompts a Google sign-in.

Step by step

1
Open AI Chat and sign in
From the sidebar, go to AI Chat. If you're not signed in yet, you'll be prompted to sign in with Google before you can send a message.
2
Type your question
Ask about anything food- or nutrition-related — a calorie estimate, a macro breakdown, advice for a goal, or what to eat with what you have. There's no fixed set of prompts; it's a normal chat box.
3
Let it update your profile
If you mention something like your weight, goal or a dietary restriction in a message, the assistant can pick that detail up and save it to your Nutrition Profile automatically, so you don't have to enter it twice.
4
Keep the conversation going
Each message you send includes the conversation so far, so you can ask follow-up questions naturally without repeating context.

Free vs. Pro limits

The free plan includes a daily message limit; once you reach it, you'll see a message telling you you've hit your daily limit and offering an upgrade to Pro for more daily messages. The app doesn't show the exact number in the interface — if you're a heavy user and want to know exactly where the line is, Pro removes the concern by raising it. Signed-in Pro users have a separate daily limit that resets at midnight UTC.

Tips

If you're sending messages very quickly, you may see a "slow down" message — that's a short rate limit, not the daily limit; wait a moment and try again.
Set up your Nutrition Profile once (or let chat build it as you go) so answers about calories and macros are personalized to you rather than generic.

Frequently asked questions

Do I need an account to use AI Chat?

Yes. Opening AI Chat while signed out prompts a Google sign-in before you can send a message.

When does my daily message limit reset?

At midnight UTC.

Will chat actually change my saved profile, or just remember things for this conversation?

It can save details you mention — like your goal or weight — to your actual Nutrition Profile, which is the same profile used to personalize What to Cook results.
