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.

Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.

Provides clean inbox prioritization and smart summaries, but lacks deep team chat integration and shared inbox workflow rules.

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

Features a unified cross-platform inbox with AI assistants, but lacks Missive's advanced team collaboration and shared conversation assignment.

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


SpecialistAutomates email triaging and executive scheduling effectively, but is structured as a virtual assistant rather than a collaborative team inbox.
