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.
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.
