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.
No-training AI extraction that turns documents and images into structured data
Define exactly which values you want pulled from a document — in the web interface or via API — and start extracting without training or configuring a model.
Handles complex PDF layouts, tables, images and photos, scans, digital Word files and web pages, and plain text files through the same define-upload-extract flow.
Prebuilt flows for invoices, resumes, contracts, receipts, bank statements, bills of lading, purchase orders, and emails, tuned to the fields each record type typically carries.
A documented API lets you embed the same extraction step into existing HR, accounting, legal, or back-office software instead of using only the web app.
