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.
Real-time AI interview assistant for live interviews and coding screens
Grab questions from live microphone audio, highlighted text, or precise screenshots of a full screen or selected region, then send them in a single action.
Stack audio, screenshots, and text snippets like a digital clipboard so multi-part questions are answered together with full context.
Scan a QR code to open a live viewer in your phone browser, read answers and trigger commands remotely while your desktop stays hidden during screen share.
Choose between multiple frontier and open models for speed, deep reasoning, or coding help depending on the round you are facing.
