Onyx is nearly cut. Leave your email and be first through the door — one email at launch, nothing else.

One assistant, every part of your life

Each module is a view of the same brain — everything cross-references everything.

Today — your command center

Score, recovery, day plan and every module on one screen. The first thing you open in the morning.

Every frontier AI, one chat

Claude, GPT, Gemini and more behind a single picker — an assistant that already knows your context.

Second Brain

Plain-markdown notes your assistant actually reads. Ask about anything you've ever written down.

Gym & health coach

A body-scan session view, set-by-set logging, and a coach that plans your training around your recovery.

Business mentor

Revenue, sessions and one exact next step — an advisor that has read your numbers before you ask.

Sleep, meals & reviews

Bedtime calculated from your day, a meal plan with macros, and a monthly review that audits everything.

Everything connects

Built on the Model Context Protocol — your tools plug straight into your assistant.
