Praex
Praex is an AI copartner running on proprietary models for the web, terminal, and phone.
Praex is an artificial intelligence copartner that runs on its own proprietary models, served directly from controlled infrastructure without third-party APIs. Users can interact with the system through the web, terminal, and mobile phone, maintaining the same agent, memory, and session across all screens. The product features three second-generation models: Velox II for everyday tasks and quick edits, Faber II for serious coding and reasoning, and Lucia II for complex problems. Users can start immediately without a sign-up, or bring their own keys and hardware to run Praex on other models. It provides direct answers and edits without unnecessary refusals, operating as a private assistant for daily work.
