Ethical AI training data marketplace specializing in multilingual speech, text, and NLP datasets.
Defined.ai is a curated marketplace and production platform for ethical AI training data, specialising in multilingual speech, text, and NLP datasets produced to rigorous data quality and ethical sourcing standards. The company collects, annotates, and licenses high-quality language data spanning conversational AI, ASR, NLU, sentiment analysis, and machine translation training across dozens of languages including low-resource and regional languages underserved by general-purpose dataset repositories. Defined.ai's ethical sourcing model — with fair compensation, informed consent, and transparent contributor relationships — differentiates it in a market increasingly scrutinised for data provenance and worker treatment. Its marketplace model allows AI teams to browse and license existing datasets or commission custom data collection tailored to specific model training requirements. Clients include major AI labs, technology companies, and automotive manufacturers building voice and language AI systems.
