## About NLP Lab
NLP Lab (previously known as Annotation Lab) is a Free End-to-End No-Code platform for document labeling and AI/ML model training. It enables domain experts - nurses, doctors, lawyers, accountants, investors, etc. – to extract meaningful facts from text documents, images or PDFs and train models that will automatically predict those facts on new documents. This is done by using state-of-the-art Spark NLP and Spark OCR pre-trained models or by tuning models to better handle specific use cases. John Snow Labs’ NLP Lab 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. Based on an auto-scaling architecture powered by Kubernetes, it can scale to many teams and projects. Enterprise-grade security is provided 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.
