Discover the Top 10 Free AI Tools for Developers
Artificial intelligence (AI) technologies like natural language processing (NLP), computer vision (CV), and machine learning (ML) are transforming software applications. With robust AI capabilities now easily accessible, developers are increasingly leveraging them to build smarter, more intuitive apps. This article will highlight 10 leading free tools to add AI superpowers to your projects!
Natural Language Processing
NLP enables analyzing and generating speech and text using AI. Developers employ it for sentiment analysis, summarization, translation, chatbots, and more. Here are 5 top free NLP tools:
DevHunt
DevHunt provides a hosted NLP API for building conversational experiences. It handles speech-to-text, NLU, intent recognition, entity extraction, sentiment analysis, and dialog management. DevHunt is free for up to 100 requests per month.
DevHunt's NLP API allows developers to quickly integrate robust natural language capabilities into their applications. It supports multiple languages and includes powerful features like named entity recognition, content classification, contextual analysis, and flexible dialog management with templating.
SpaCy
SpaCy is an open source NLP library for Python. It can tokenize text, tag parts of speech, recognize named entities, analyze sentiment, and build statistical models. SpaCy integrates word vectors and convolutional neural networks.
AllenNLP
AllenNLP provides reference implementations of state-of-the-art NLP models like ELMo, BERT, and GPT-2. It makes model configuration and training easy.
GenSIM
GenSIM is a Python library for topic modeling, document indexing, and similarity retrieval for large datasets. It includes word2vec, doc2vec, TF-IDF, and more.
NLTK
NLTK provides Python text processing libraries and resources for classification, tokenization, tagging, parsing, and more.
Specialized Tools
Leading free tools for building chatbots and voice assistants include Dialogflow for natural language understanding, Rasa for conversational AI, Amazon Lex for voice/text bots, Azure Bot Service, and IBM Watson Assistant.
