Imagine a world where AI can handle your work while you sleep - organizing
your research materials, drafting a report, or creating a presentation you need
for tomorrow. However, while current digital agents can perform simple tasks,
they are far from capable of handling the complex real-world work that humans
routinely perform. We present PC Agent, an AI system that demonstrates a
crucial step toward this vision through human cognition transfer. Our key
insight is that the path from executing simple "tasks" to handling complex
"work" lies in efficiently capturing and learning from human cognitive
processes during computer use. To validate this hypothesis, we introduce three
key innovations: (1) PC Tracker, a lightweight infrastructure that efficiently
collects high-quality human-computer interaction trajectories with complete
cognitive context; (2) a two-stage cognition completion pipeline that
transforms raw interaction data into rich cognitive trajectories by completing
action semantics and thought processes; and (3) a multi-agent system combining
a planning agent for decision-making with a grounding agent for robust visual
grounding. Our preliminary experiments in PowerPoint presentation creation
reveal that complex digital work capabilities can be achieved with a small
amount of high-quality cognitive data - PC Agent, trained on just 133 cognitive
trajectories, can handle sophisticated work scenarios involving up to 50 steps
across multiple applications. This demonstrates the data efficiency of our
approach, highlighting that the key to training capable digital agents lies in
collecting human cognitive data. By open-sourcing our complete framework,
including the data collection infrastructure and cognition completion methods,
we aim to lower the barriers for the research community to develop truly
capable digital agents.
