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.

Share and access study materials worldwide — with AI study tools built in
Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
