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.
Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
