Jev tools for real jobs
Each tool is one Jev question set built for a specific job. Open one to run it on your own text, see what Jev returned on a real example, and learn how to turn it into a step in your pipeline.
Have a whole file or a whole website instead of one text? Run it as a bulk job. See bulk jobs
