AI-assisted data annotation companion for faster, smarter labeling
The extension proposes likely labels or annotations as you work, so you can confirm a suggestion instead of classifying each item from zero.
Runs entirely in the browser via the Chrome Web Store, with no server setup, plugin dependencies, or account creation required.
Acts as a companion layer over the annotation pages you already use, so there is no need to migrate your dataset or tooling.
The developer declares that user data is not sold or shared and is not used for unrelated purposes.

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.

SpecialistRelies heavily on managed human-in-the-loop workforce services for data validation, offering less self-serve technical tooling than Labelbox.
Delivers enterprise-grade labeling and model evaluation at massive scale, but often requires higher enterprise budgets than Labelbox.
