01 / HOW

Two minutes · then it runs itself

Set it up once. Never fill in a form again.

01 — SIGN UP

Create a Maxim account.

Email or Google. That's the whole form.

02 — CONNECT

Add Maxim to your chat app.

Paste maxim.fit/api/mcp as a connector in Claude or ChatGPT, or run one command in Claude Code, and sign in. No API keys, nothing to install.

03 — DONE

Your chat app takes it from here.

Tell it about your life and it writes the protocol. Mention a change and it updates it. Open Maxim on your phone and do the day.

Inside Maxim — your chat app does the thinking

02 / FEATURES

Maintained for you

Your chat app keeps it current. Maxim keeps it readable.

REMEMBER

Say it once.

Mention a bad knee, a new work schedule or a food you hate, and your assistant saves it to Maxim. Every future edit respects it.

EDIT

Change anything in plain English.

“Move training to mornings.” “More protein at Meal 1.” Your assistant makes the change and Maxim shows the updated day.

CONNECT

No new app to learn.

Claude, ChatGPT, Claude Code — the assistant you already talk to every day is the one that maintains your protocol. Maxim is where it lives.

VERSION

Every change tracked. Anything revertable.

Every change your assistant makes is a new version. Didn't like one? Revert in a tap, or just say so in chat.

PROGRESS

Watch the trend, not the day.

Adherence, streaks and weekly completion — logged in seconds each day, in the app, with no wearable required.

TODAY

Today first. Everything else second.

Schedule, diet, supplements and training in one dense daily view. Mono numbers, explicit units, 24-hour times. Scan it once and go.

03 / PRINCIPLES

Simple on purpose

Three things we won't compromise on.

Maxim doesn't try to be your AI. It's the place your AI keeps your protocol.

OPEN · BY DEFAULT

One URL. Any assistant.

Maxim uses MCP, the open standard Claude, ChatGPT and Claude Code all speak. Sign in once and you're connected. Every connected app is listed in Settings and can be disconnected in a tap.

SAFE · WRITES

Nothing gets overwritten by accident.

Every change your assistant makes is checked against the version it last saw and lands as a new version. If two edits collide, the second one waits. Nothing is ever lost.

04 / FAQ

Common questions

Things you should know before you join.

Which AI can I use? +

Claude (web and desktop), ChatGPT and Claude Code today, plus anything else that supports MCP connectors. Add https://www.maxim.fit/api/mcp as a connector and sign in with your Maxim account.

Does Maxim run its own AI? +

No. Your chat app does all the thinking. Maxim stores your protocol, keeps every version, and shows you today. Nothing about you is sent to a second model you didn't choose.

What can my assistant actually do? +

Write your protocol, edit it, revert it, and remember your goals, requirements and notes. That's it. It only sees your account, and you can disconnect it from Settings at any time.

How much does it cost? +

Free to start. See pricing for plan details.

Is this medical advice? +

No. Maxim Fit is a protocol tool, and the protocol is written by the assistant you connect. It's not a substitute for a physician. For anything beyond standard fitness — pre-existing conditions, prescribed medications, pregnancy — talk to your doctor first. Export your protocol as PDF and bring it to the appointment.

How do you handle my data? +

Your protocols and settings live in your Maxim account. An assistant only gets access through a token you approve, scoped to your account and revocable from Settings. We never sell or share data. Export everything as PDF at any time.

Is there an app? +

Maxim Fit runs as a web app on iPhone, Android and desktop — nothing to install. Open maxim.fit in your browser and use "Add to Home Screen" to launch it full-screen like a native app.
