NLP Lab is a no-code platform for document labeling and AI/ML model training that allows domain experts to extract meaningful facts from text documents, images or PDFs and train models that will automatically predict those facts on new documents. It uses Spark NLP and Spark OCR pre-trained models or can tune models to better handle specific use cases. It supports the end-to-end process from starting an annotation project to the deployment of a trained model, all without writing a line of code. It has an auto-scaling architecture powered by Kubernetes and provides enterprise-grade security for free, including support for air-gap environments, zero data sharing, role-based access, full audit trails, MFA, and identity provider integrations. It allows powerful experiments for model training and finetuning, model testing, and model deployment as API endpoints.
