I like how easy it was for my team members who have limited experience in AI/ML tools or coding themselves but are interested enough about this field of expertise.
It's very convenient when they realize there isn't much effort required as long one has an idea what he wants his program should do! Nothing at all really comes up negative because everything works well out-of box from simple configuration steps such as adding data points etc., even if someone doesn’t know code yet can understand most concepts easily through video tutorials provided by shelf itself along with other support materials including API documentation which helps users get started quickly!! The only thing would be probably some minor tweaks here &there could work better - maybe having multiple user profiles setup so each member does not need another login just to test their programs? As stated above though its pretty intuitive once basic features start working (such as text retrieval). In addition since your using existing APIs already available elsewhere then integration into any web app.
