Reasoning you can audit, on a key you own.

DUD3P0 is the family's research & reasoning draiyod: BYOK chat (OpenAI, OpenAI-compatible, or Anthropic native), receipt-backed research missions with resume and completion notifications, DUD3 for Mac and its tools for your AI apps, a Rust turn planner, a logic lab, and real code — all user-routed, no Everplay chat backend. The screenshots below are the real App Store capture (1320×2868).

The real capture set for the App Store 6.9″ slot — actual app pixels, not mockups.

People who do real research and reasoning on their phone and want to check the work: analysts, engineers, system designers, and BYOK power users who would rather bring their own model key than rent a subscription — and who care that the app keeps their key and their dossiers on their own device.
