The environments frontier AI trains on, and the agents that do the recurring work
Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.

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.
