Getting started
What Brett is, what you need, and the one choice to make before you install.
What Brett is
Brett is a Mac app that puts Brett Hawes' functional health method inside the AI app you already use, Claude or ChatGPT. You ask a clinical question or paste a de-identified case, and the answer comes from Brett's own practitioner material, reasoned the way he teaches it.
It is a working assistant for trained practitioners, not a course. It draws on Brett's Digestive Health Practitioner Masterclass, his Women's Hormone course (built around DUTCH testing), his case studies and guest lectures.
- Grounded answers. Brett answers from Brett's material first. When the material doesn't cover something, it says so and labels anything else as general knowledge.
- Brett's order of operations. Red flags first, support the foundations before adding antimicrobials, low and slow, phased 30-day protocols.
- Only your modules. Your license unlocks Digestive Health, Hormone Harmony or both. Content you aren't licensed for stays locked.
- Drafts for you, not your client. Every output is a draft for the practitioner to review. Brett never starts, stops or changes medications, and sends red-flag cases to the client's doctor.
What you need
- A Mac running macOS 13 or later.
- An AI app: the Claude desktop app on a paid plan (Pro, Max, Team or Enterprise), or the ChatGPT desktop app.
- An internet connection. Brett needs one to work.
- A Brett license. Buy one at askbrett.app/buy.
Brett doesn't run on iPhone, iPad, Windows or in a web browser.
Choosing Claude or ChatGPT
Your license is activated for one AI app, Claude or ChatGPT, and one account in it, the first time you use Brett. Pick the app you already use for client work, and sign in with that account before you install.
Brett works the same way in both. In Claude you open the commands with /; in ChatGPT you open them with @. Moving your license to the other app later needs our help.
Buying a license
Buy at askbrett.app/buy. Use an email address you can open on your Mac, because that's where your sign-in link goes. Your license includes Digestive Health, Hormone Harmony or both, and you can add the other later from Brett's Home page.
