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 batch cropping and split scans into individual photos
A custom detection algorithm outlines every photo on a scanned page and numbers each crop box, so nothing is missed by hand.
Crooked or tilted photos are detected and straightened automatically during the crop step.
Apply one identical crop layout across an entire batch, keep the crops linked, and save the layout as a reusable template.
Lay uniform, evenly spaced crops across negatives, photo-booth strips, and contact sheets in a single pass.
