AI-powered localization and translation platform for global content
Centralise translators, vendors and reviewers with shared translation memories, glossaries and style guides.
Automatically selects the best machine translation engine or LLM for each asset based on content type, quality and cost.
Score and automate translation quality checks so substandard output is caught before publication.
Build custom workflows and connect any tool or engine through open APIs and integrations.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
