Monthly API requests

Tinq.ai is a great tool. It has a lot of potential.
I am no ai expert by any means, so I need something that is easy enough to add to my app.
Tinq's classifiers are great for that job. I also use the online rewriter from time to times to write online copy, and it does a good job.

Freelance Copywriter

I really like using Tinq in my app. This is by far the most versatile rephrasing (NLP) API that I've used. I run a community website and the classifier is very handy. It helps me quickly moderate what is happening in the community and prevent hateful speech and other unexpected behavior.
