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.
Meter, budget and route every LLM call so AI spend is controlled before it happens
Routes and records every LLM and agent call across OpenAI, Anthropic, Google, xAI, OpenRouter and Ollama, attributing cost down to individual steps, tools and workspaces.
Hard and soft caps evaluated in the request path, with HTTP 402 quota enforcement and Slack alerts so limits trigger before the money leaves your account.
Sends each request to the cheapest model that still satisfies your quality and latency thresholds, and fails over automatically when a provider slows down or errors.
Gross margin per customer and feature, forecasts with confidence bands, commitment burn-down for cloud and vendor contracts, plus auditable chargeback exports and invoice runs.
