Own the whole stack

The models you talk to are ours: tuned by us, served by us, answerable to no third party. Prefer your own keys or hardware? That works too. Your work is not a data funnel.

02 · Everywhere

One copartner, every screen

Start a task in the terminal, steer it from your phone, review it on the web. Same agent, same memory, same session.

03 · Direct

Answers, not lectures

Praex does the work and answers the question. No hand-wringing, no hedging, no refusing the reasonable. Private by design.

Three minds. First generation.

The models behind Praex: tuned by us, served from infrastructure we control, sized to the job. Or bring your own keys and run Praex on any model, free.
