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.
AI CAPTCHA solving for browsers and automation pipelines
Chrome, Firefox, and Edge add-ons solve image and audio challenges in-page, including on sites that require the official extension.
Returns verified tokens for Cloudflare Turnstile and Google reCAPTCHA v2/v3 without launching a browser.
Supports reCAPTCHA, Turnstile, FunCAPTCHA, Arkose, AWS WAF, GeeTest, Lemin, PerimeterX, and text CAPTCHAs.
Python (PyPI) and Node.js (npm) libraries plus a REST API for any other language.
SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.
