Turn complex documents into clean, structured data via API
Advanced extractors read documents without predefined templates, so new layouts and unexpected formats are handled without extra configuration.
Accepts PDFs, images, Word, Excel, PowerPoint, XML and EDI files, with automated email and FTP connectors for bulk processing.
Supports 100+ languages with automatic translation and extracts both printed and handwritten content from forms, notes and receipts.
Automatically detects invoices, IDs, contracts and POs, and parses complex, nested or borderless tables into Excel, CSV or JSON.
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.
