AI document parsing that turns PDFs and emails into structured data
Name the fields you want in plain English and the AI pulls them from clean digital PDFs, blurry scans and email bodies, adapting to new layouts automatically.
Forward documents to a dedicated email address, drag and drop them in the app, or push them in via the API, webhooks or automation platforms.
Character recognition converts photographed receipts and scanned paperwork into machine-readable text before extraction.
Format, clean and validate every extracted field so totals, dates and IDs arrive consistent rather than as raw strings.
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.
