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.

Start a task in the terminal, follow and approve it from your phone with Remote Control, and chat on the web.

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