Your health.
Your questions.
Your next step.

An Assistant that knows the context you’ve saved—and can help you do something with it. Understand your results, build a custom stack and organise your routine, in one conversation.

Explore the example first. No account needed.

What’s changed in my blood tests?

Your ApoB is lower than it was 18 months ago. Let’s look at the trend in context.

Apolipoprotein B96 mg/dL

124 → 96 mg/dL · Mar ’25 to Sep ’26

A change is worth understanding. It doesn’t prove what caused it.

Personal starts with context

More than a generic answer.

Your saved results, goals, stacks and schedule give the Assistant context. Whatstack’s Library gives it references to draw on. Together, they help it respond to your situation.

Ask for the outcome

It can do the organising, too.

You stay in control. Review proposed changes before applying them, then see what changed in the app.

Understand

“What changed in my latest results?”

Compare trends, explain a marker and put the numbers in context.

Take action

“Move my evening stack to bedtime.”

Create or edit stacks, update doses and schedules, and manage goals without finding every setting.

Keep the conversation useful

A weekly moment to reflect.

Your in-app weekly review brings together saved activity and one next step. Ask Fleming to put it in context with your results, goals and current routine. You can pause suggestions across your devices.

See reviews and progress in action →

When you’re ready, make it personal.

Create an account and start with a goal or your existing routine. Add health data as you go. The Assistant uses the context you’ve saved; a blood test isn’t a prerequisite.

A few things worth knowing

Is it trained on my health records?

It uses your saved information as context when responding. That’s different from training a separate model on your records. You can review the data you’ve saved in your account.

Can it actually change my plan?

Yes. Supported actions include creating and editing stacks, doses, schedules and goals. Proposed changes are shown for review, and completed actions have a receipt; supported actions offer Undo.

Is it a replacement for a clinician?

No. It helps you understand information and organise a plan. Medical decisions, diagnoses and treatment need a qualified clinician.
