AI-powered localization and translation platform for global content
Centralise translators, vendors and reviewers with shared translation memories, glossaries and style guides.
Automatically selects the best machine translation engine or LLM for each asset based on content type, quality and cost.
Score and automate translation quality checks so substandard output is caught before publication.
Build custom workflows and connect any tool or engine through open APIs and integrations.
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.
