We got a demo from that but no response from them after sending out an inquiry mail. That's a little worrying when you think from a user's point of view.
Edit to the review: The team had responded and the delay was due to a busy schedule of theirs. They were supportive. The tool is excellent but we could not onboard because of some additional features that we wanted which they have agreed to work upon.
Love it! Crafting docs is normally a pain, and people too often wait until very late in the dev timeline to put something together. Theneo makes it easy to do on the fly!
