8 Best NLP Tools (2024): AI Tools for Content Excellence

Natural language processing (NLP) is a field within artificial intelligence that enables computers to interpret and understand human language. Using machine learning and AI, NLP tools analyze text or speech to identify context, meaning, and patterns, allowing computers to process language much like humans do. One of the key benefits of NLP is that it enables users to engage with computer systems through regular, conversational language—meaning no advanced computing or coding knowledge is needed. It’s the foundation of generative AI systems like ChatGPT, Google Gemini, and Claude, powering their ability to sift through vast amounts of data to extract valuable insights.
