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.

Turn your MCP server into a live, shareable interactive playground
Connect an MCP server over SSE or streamable HTTP and get a live, isolated playground in minutes — no DevOps tickets and no risk to production.
Automatic introspection produces documentation for every tool plus a chat interface connected to the real MCP tools, with sample history.
Share a playground URL or embed the widget on your own site or app so visitors can try the server without installing anything.
Every chat and tool call is captured so teams can see who engaged and where users or agents get stuck.

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.

Offers robust multimodal annotation and workflow automation, featuring slightly more intuitive data curation pipelines for computer vision teams.

SpecialistTrack, evaluate, and ship AI models and agents in one connected environment.


The intelligent documentation platform that keeps itself up to date
Specializes in advanced computer vision and physical AI data pipelines, though with a narrower focus than general text-and-image labeling.

Free / Open-sourceProvides a flexible open-source alternative for custom data labeling, but requires self-hosting and manual infrastructure maintenance.


SpecialistFocuses strictly on LLM evaluation, testing, and observability rather than raw data annotation and training dataset curation.
