The coding agent that learns your coding taste
A continuous reinforcement-learning layer that turns every accept, reject and manual edit into a signal, then converts recurring patterns into reusable project-level skills.
Automatically repairs malformed tool calls so weaker open-weight models can complete agent loops reliably, levelling them up toward frontier performance.
Use an interactive CLI for pairing, a headless flag for scripting, or a background sandbox agent for longer autonomous jobs.
Custom /agents and persistent /memory carry project context across sessions so you stop re-explaining your codebase and conventions.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
