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.
Studio-quality podcast and video recording, editing, and publishing in your browser
Every participant records locally on their own device, capturing up to 4K video and 48kHz uncompressed audio in separate tracks that stay sharp regardless of connection quality.
Edit video by editing the transcript — search, cut, copy, and paste words and the footage updates. AI then removes filler words and silences or fixes eye contact in one click.
Turn a finished session into promotional assets: short clips optimized for each platform, thumbnails, headlines, show notes, transcripts, and translations or dubs in over 30 languages.
Broadcast in full HD 1080p to unlimited destinations simultaneously, or host webinars with registration, branded emails, Q&A, live call-ins, polls, and HubSpot lead capture.
