Your portfolio's AI analyst, powered by alternative data
Scores stocks using web traffic, app downloads, job postings, social mentions and insider activity rather than price charts alone.
High-conviction buy and sell signals plus real-time notifications when a holding spikes in popularity, sentiment or insider trading.
Upload a brokerage screenshot and get a 0–100 score for every holding, blended into a single portfolio score.
Ask plain-English questions about your holdings and get answers grounded in live scores, fundamentals and alt-data signals.
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.
