Eco-minded neural engine for fast, accurate AI transcription
Convert audio and video to text with high claimed accuracy, including automatic language detection and support for regional accents and specialized vocabulary.
Automatically identify and label different speakers so interviews, meetings and multi-person recordings produce usable, attributed transcripts.
Neural upsampling cleans background noise and enhances speech frequencies, improving results from lower-quality recordings.
Export SRT subtitle files for video work, plus PDF and DOCX documents for reports, notes and academic use.
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.
