01 — Talk

Say what you're optimizing for

The agent composes a protocol from 1,500+ quality-gated brands while you watch — swap, cheapen, re-dose by chatting. Every stack becomes a real page you can share or remix.

02 — One protocol, any brand

Mix across sellers

An Athletic Brewing six-pack, a bottle of Seedlip, Olly Sleep — three brands, one build. Or start from a pre-built protocol from Huberman, Sahil, Naval, and others, and remix it into yours.

03 — Pay the brand directly

No middleman on checkout

Each order completes on the brand's own site. Your card, address, and order go straight to them. We never touch your payment info.
