# UseDesktop > Verifiable RL task environments and trajectory data for computer-use agents. UseDesktop is a research lab and software platform that turns real desktop workflows into verifiable RL task environments and high-quality trajectory data for computer-use agents. The company supplies frontier AI teams with workflow data packages for post-training, evaluation, and reinforcement learning. In 2026, UseDesktop is positioned as an RL environment startup for computer-use agents: reinforcement learning environments for agent evals, verifier-backed tasks, reward signals, and high-quality workflow trajectory data. ## What UseDesktop Does - Captures long-horizon desktop workflow trajectories across browsers, files, spreadsheets, PDFs, portals, and legacy apps. - Converts workflows into reproducible RL task environments with task goals, UI states, traces, artifacts, outcomes, verifiers, eval splits, failure traces, and reward signals. - Benchmarks model attempts with pass@k reports, verifier audits, failure taxonomies, and contamination checks. - Supports two customer paths: teams can use Desktop as end-to-end workflow data infrastructure, or UseDesktop can supply verifiable RL task environments and trajectory datasets with proof. ## Core Pages - https://usedesktop.com/ - Main landing page for verifiable RL environment and trajectory data infrastructure for computer-use agents. - https://usedesktop.com/explore - Target workflow classes for verifiable RL task environments, trajectories, verifiers, eval reports, and reward signals. - https://usedesktop.com/start - Install Desktop and start capturing real workflows. - https://usedesktop.com/about - Research lab thesis and infrastructure positioning. - https://usedesktop.com/enterprise - Frontier-team workflow data, RL task environment, and post-training pipeline. ## Key Concepts - CUA: computer-use agent. - RL task environment: a reproducible task package with state, actions, outcomes, verifier logic, reward signal, and train/eval split. - Agent evals: model runs against verified computer-use tasks with pass@k, failure modes, verifier results, and reward signal analysis. - Trajectory data: human or agent action sequences with screenshots, UI states, artifacts, failures, corrections, and final outcomes. - Verified data: workflow data with active testing, verifier audits, difficulty calibration, model comparisons, and contamination checks. - Real workflow data: operational desktop work performed by people solving actual tasks, not synthetic benchmark-shaped tasks. ## Contact - Website: https://usedesktop.com - Email: support@usedesktop.com - Book a call: https://cal.com/seungju-chae
