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.

Draw the architecture; Solarch writes the code that matches it
Model the whole backend — controllers, services, repositories, tables, DTOs and queues — on one surface with 16 semantic edge types across 8 families.
An illegal connection such as wiring a controller straight to a table is rejected the instant you draw it, based on 7 anti-patterns and 3 conditional checks.
Stage one compiles the graph deterministically into skeletons with zero tokens; stage two uses surgical AI to fill only the empty function bodies.
A LangGraph-powered architect grounds every plan in a vector-indexed library of canonical patterns instead of autocompleting from scratch.

#1SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.
#2
SpecialistRelies heavily on managed human-in-the-loop workforce services for data validation, offering less self-serve technical tooling than Labelbox.
#3Delivers enterprise-grade labeling and model evaluation at massive scale, but often requires higher enterprise budgets than Labelbox.
AI diagrams and technical design docs built from your code and systems
Free / Open-sourceReactive TypeScript backend with database, functions and AI gateway

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

Agent orchestration platform for your whole software development lifecycle

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

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.
