• NLTK – A classic library for NLP research, offering lexical resources, corpora, and teaching materials. Great for beginners and educational use.

• Stanford CoreNLP – A suite of pre-trained models for POS tagging, named entity recognition, sentiment analysis, and parsing. Built in Java but usable via APIs.

• StanfordNLP – A PyTorch-based replacement for CoreNLP, optimized for deep learning NLP models in multiple languages.

• LIWC – A proprietary tool for emotion, tone, and psychological analysis of text. Often used in behavioral studies or emotion-aware chatbots.

• TagHindi – A tool for POS tagging and parsing Hindi text. Useful for multilingual AI projects focused on Indian languages.
