Agent traces · Work traces

The hypervisor
for RL.

Ground truth others can't trace.

  • HypervisorRuns your agent unchanged and records processes, network egress, policy decisions, and file changes below the harness.
  • W8 browser engineOur Chromium engine records the full page state at every step: exact values, controls, and off-screen content.

Our team turns both into training data for frontier labs and custom models for enterprises.

For frontier model labs

Datasets, evals, and RL environments.

Built from traces nobody else captures. Accepted by frontier-lab quality gates.

  • Full page state, every step
  • Runtime truth below the agent
  • Deterministic rewards

For enterprise AI teams

Small models trained on your agents' real work.

Bring your production harness. Change almost nothing.

  • No harness rewrite
  • Only verified runs in training
  • Frontier fallback at your gateway

An OpenShell-based sandbox records processes, egress, policy decisions, and file changes, whatever the agent logs.

Our Chromium browser records the page state screenshots miss: exact values, controls, and off-screen content.

FAQ

Questions.

What does WootzApp sell?

Datasets, evals, and RL environments for frontier model labs, and custom small models for enterprises. Both are built from traces captured by our hypervisor and the W8 browser.

What is a work trace?

A recording of an expert doing a real task inside our hypervisor and W8: actions, runtime events, and page state at every step. An agent trace is the same record produced by an AI agent.

Do we need to change our agent?

No rewrite of core agent logic and no tracing SDK. Setup covers image packaging, sandbox configuration, credentials, and gateway routing.

Do you resell enterprise data?

Not by default. Enterprise training and model-lab data are separate contracts. External licensing requires explicit rights and permitted use.

What your agent did matters more than what it said.
