   Polarity

   Polarity is sandboxed eval infrastructure for AI agents. It monitors every agent decision in production, surfaces failure patterns before users hit them, and turns trajectories into evals that compound agent reliability over time. Each task runs inside an isolated Docker sandbox preloaded with real backing services (Postgres, Redis, S3, internal APIs).

   Trainer

   Trainer lets you train AI agents by simply recording a task once — no prompts, no labeled data. It captures every click, keystroke, and intent as you work, then turns that workflow into a reusable agent that can repeat the process reliably. Trainer doesn't rely on fixed coordinates or pixel positions; it builds a semantic understanding of the UI (what the element is, surrounding context, labels, and the intent behind the action) so the agent can still find the right element when buttons move or layouts shift. Works at the level of intent, not rigid steps, so it can adapt when small variations appear in the flow.

   Viberia

   Viberia is a spatial command center for your AI agents, inspired by strategy games like Civilization. Your whole AI org lives on an isometric map, with status icons showing who is blocked, who is asking, and who is done. Zoom in to chat with any agent, pick any model, and bring your own keys. Agents collaborate, build their own little teams, and pick up new skills as they go, with docs, terminals, and browsers built in.
