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.
AI-powered resume scoring, skill insights and interview feedback for data-driven career preparation
Every resume is evaluated across more than 100 parameters covering language quality, structure, impact statements, competencies and presentation, then benchmarked to produce a target-specific score with prioritised fixes.
Machine learning and NLP detect hard and soft skills from your document and compare them with requirements for the roles and industries you are aiming at, so guidance stays role-relevant.
Uploaded practice interviews are analysed for verbal and non-verbal cues such as speech pacing, eye contact, facial expression and content delivery, producing structured feedback for improvement.
Dedicated tracks for candidates, corporates and universities let career centres and talent teams configure modules, monitor usage and integrate VMock into existing coaching workflows.
