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.
Count items in real time with AI-powered object detection
Count items directly from your camera or a selected image using computer vision algorithms built for speed and accuracy.
Ready-made templates for industrial and commercial categories such as pipes, boxes, pallets, pills, coins, tires, and electronic parts.
Review every count and add or remove items before saving, so the final number reflects what you actually see.
Export counts as PDF reports that include location data, useful for stocktakes, audits, and site documentation.
