Insights

Your data can tell a clearer story.

FATChat looks across trends in your own history and surfaces observations worth noticing. Insights are context — never diagnosis or dosing advice.

See how Insights work
Example observations
HYDRATION + PROGRESS

Weeks with more consistent hydration have coincided with steadier check-ins and activity in your history.

SLEEP + FATIGUE

Your fatigue check-ins have appeared more often during shorter-sleep periods than on injection day alone.

DOSE CHANGE CONTEXT

Symptom check-ins increased after your recent medication change, then moved back toward your earlier pattern.

Connected context

Designed to connect the health data you already have.

Family Circles

Support without surveillance.

Family Circles are built for encouragement, not ownership of someone else’s health record. Each person has an independent account and decides what to share.

Questions

Simple answers to important things.

Is FATChat medical advice?

No. FATChat helps organize and explain patterns in your own data. It does not diagnose conditions or tell you how to dose medication.

Can my family see my health data?

Not unless you choose to share it. Family Circles are designed to be private and permission-based.

Does FATChat sell my health data?

No. FATChat is not designed around selling identifiable personal health data.

Do I need a wearable?

No. FATChat works with manual check-ins. Connected health sources can add context when those integrations become available.

Which GLP-1 medications can I track?

The product architecture is designed for medication and dose history rather than a single brand. Availability in the app will depend on the medication catalog at launch.

Your history. Your context.

Make your journey easier to see.

Start with simple daily tracking. FATChat helps turn that history into a clearer picture over time.
