In the previous article, we discussed the 10 best free, open-source libraries that can be used for categorizing text, which you can find here. But that is an ideal case when you’re neck-deep into coding and machine learning and have the time to spend hours investing in development. So if you’d prefer to get started with a more generic framework, without really getting under the hood, this is the article for you. In this article, we will breakdown the 10 best MaaS/SaaS (Machine Learning as a Service) APIs that can help along your data journey and provide valuable insights without you breaking your head for hours learning about coding. Using ready-to-access solutions, without any prior setup, SaaS/MaaS platforms can help you do complex tasks in machine learning and NLP without being an expert. Thus, your job gets a lot easier without any prior knowledge about the technicality, faster, and more efficiently helping bootstrap your business journey. With NLP models that have been pre-trained to be used without any coding knowledge, MaaS tools have way lot to offer.

Now that we know the basics of how a MaaS platform can help businesses that are looking for a fast and effective use in machine learning, let’s tune in to our top 10 best MaaS APIs for Text Classification.
