Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.

#1
Large consumer panel for market research surveys, but lacks Prolific's specialized focus on academic studies and AI tuning.
Offers a streamlined no-code builder for deploying custom AI agents, but lacks Dify's open-source flexibility.

Free / Open-sourceA self-hosted chat interface for running local LLMs, though lighter on complex visual workflow orchestration.

SpecialistThe environments frontier AI trains on, and the agents that do the recurring work

Enterprise-grade data annotation and AI alignment workforce, but less self-serve for academic study recruitment and casual surveys.


SpecialistProvides advanced programmatic frameworks for document parsing and RAG pipelines, but requires coding instead of visual canvases.


SpecialistAI data infrastructure for building production-grade models

SpecialistSpecializes in video-based consumer interviews and AI qualitative analysis, but less focused on quantitative academic survey panels.


SpecialistSources verified B2B professionals and healthcare experts for specialized research, but lacks broad general-population academic panels.

Free / Open-sourceAn open-source automation platform combining visual flows with AI steps, though geared more towards general app integration.

Built for scaling multi-agent workforces and B2B task automation, though less focused on open-source RAG pipelines.
