The best session capture agent for computer-use training — works on real software.

Where AI learns to work.

Turn any workflow to a structural dataset to train AI models & deploy self training models with repeatable training environments.

How models learn

Three main stages of model training.
All require deep-tier data to diversify.

01Text → patterns

Pretraining

Trillions of tokens of text teach language, facts, and reasoning patterns. But public text is finite, within a few years it runs out.

02Demonstrations → behavior

Supervised fine-tuning

Models train on the expert demonstrations and imitate the shown behavior, as a child learns from watching.

03Outcomes → reliability

Reinforcement learning

Models output a result, get scored on the outcome, and update next time. Every run gets further than the last.

Thesis

Model needs the actual work, not a description of it.

Volume is easy. Signal is rare. As few as 312 augmented human trajectories produced a 141% relative improvement over the base model - because every one of them was real work.
