Explore your Cronometer data through conversation with ChatGPT.
The Cronometer plugin for ChatGPT gives Gold subscribers another way to explore their nutrition and health data.
Once connected, you can ask ChatGPT questions about your Cronometer data using everyday language. You can use it to identify trends, create summaries and explore connections between different parts of your health journey.
The plugin is one of many tools available to Cronometer users. It complements the detailed tracking, charts and insights in Cronometer while offering a more conversational way to interact with your data.
What can I do with the plugin?
You can use ChatGPT to explore your Cronometer data in ways that fit your goals and interests. For example, you could ask:
- “How has my protein intake changed over the past three months?”
- “Do you notice any patterns between my sleep and nutrition data?”
- “Which nutrients have I consistently fallen short on lately?”
- “Compare my average calorie intake on weekdays and weekends.”
- “Summarize the trends in my weight and energy intake.”
- “Suggest some questions I could explore based on my data.”
You can ask follow-up questions, request different summaries or combine insights from Cronometer with other information and tools available in ChatGPT.
Responses are generated by ChatGPT, not Cronometer, and do not represent advice or recommendations from Cronometer. The quality of ChatGPT’s responses depends on your question, the available data and any other context you provide. Responses may contain errors and should not replace advice from a qualified healthcare professional.
What data can ChatGPT access?
ChatGPT receives daily totals, not individual diary entries. For example, it can see your total calories, protein or carbohydrates for a day, but it cannot see which foods, meals or recipes contributed to those totals.
Biometrics are also provided as daily summaries rather than individual, timestamped readings. This approach protects Cronometer’s food database and supports our data licensing agreements.
ChatGPT can retrieve up to 90 days of data at a time. Those 90 days can be from any period in your Cronometer history. To explore a longer period, ask for another date range in a follow-up prompt.
You choose whether to connect your Cronometer account. Before authorizing the integration, review the terms and privacy information provided during setup.
Who can use it?
The Cronometer plugin for ChatGPT is available to individual Cronometer Gold subscribers. It is not available to Cronometer Pro accounts or to clients connected to a Cronometer Pro professional. Upgrade to Gold here.
You will also need your own ChatGPT account. A paid ChatGPT subscription is not required. You can connect using a free account.

Another tool for exploring your data
The plugin is designed to complement the features already available in Cronometer. It can be especially useful when you want to ask a specific question, investigate a pattern or create a plain-language summary.
Think of it as an additional tool for understanding your data, not the final word on your nutrition or health.
Frequently Asked Questions
Can it log food or change my diary?
No. The plugin is read-only and cannot add, remove or edit anything in your Cronometer diary.
Can it see the foods and meals I logged?
No. The plugin receives aggregate day-level metric values. It does not receive food names, brands, recipes, serving amounts, meal structure, notes or diary timestamps.
How much history can it analyze?
The plugin can retrieve up to 90 days of data per request. You can explore more history by requesting additional date ranges separately.
Is ChatGPT’s answer guaranteed to match Cronometer?
No. Cronometer provides the structured source data, but ChatGPT generates the interpretation and can make mistakes. Verify totals and targets in Cronometer, and discuss health decisions with a qualified professional.
Is this medical advice?
No. The plugin is intended for exploratory wellness and data questions. It is not intended for diagnosis, treatment, medication changes or emergency guidance.
Is my data used to train OpenAI models?
This depends on the OpenAI product, plan and settings you use to access the plugin. Refer to OpenAI’s current policies and your account settings to understand how OpenAI may use your data.
By authorizing the plugin, you are agreeing to provide OpenAI with access to the Cronometer data made available through the integration.
Why might some data be missing?
A value may be absent because it was not logged or because it cannot be represented as a daily metric.
What biometric information does the plugin receive?
The plugin receives daily summaries for the requested biometrics. It receives no more than one value per biometric per calendar day, along with the unit and reporting rule. A daily summary may represent several readings recorded on the same day.
