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.

Highlight your data, get a working regular expression back — no regex expertise required
Paste up to 4000 characters and highlight the exact substrings you want to capture — the AI derives the regex from your examples rather than from a written description.
Several independent AI agents each return their own pattern, so you can compare approaches and pick the one that generalizes best instead of trusting a single black-box answer.
Every candidate pattern is applied to your text instantly, showing the full list of matched strings so over-matching and missed entries are obvious at a glance.
Click a highlighted string to remove it and the agents re-run, letting you steer the result by tuning examples in seconds.
