+## Pricing
+
+Note that there is no cost to using ClassifAI and that both IBM Watson and Microsoft Azure have free plans for their AI services, but that above those free plans there are paid levels as well.  So if you expect to process a high volume of content, then you'll want to review the pricing plans for these services to understand if you'll incur any costs.  For the most part, both services' free plans are quite generous and should at least allow for testing ClassifAI to better understand its featureset and could at best allow for totally free usage.
+
+The service that powers ClassifAI's Language Processing, IBM Watson's Natural Language Understanding ("NLU"), has a ["lite" pricing tier](https://www.ibm.com/cloud/watson-natural-language-understanding/pricing) that offers 30,000 free NLU items per month.
+
+The service that powers ClassifAI's Image Processing, Microsoft Azure's Computer Vision, has a ["free" pricing tier](https://azure.microsoft.com/en-us/pricing/details/cognitive-services/computer-vision/) that offers 20 transactions per minute and 5,000 transactions per month.
