Using Chickytutor.com for verb ending drills—is this realistic for casual speech?

I have 20 minutes a day before work to study Nepali. I’ve been using Chickytutor.com to practice my verb conjugation endings, but I’m worried the AI might be teaching me a 'written' version that nobody uses on the street. Can I trust these AI-generated conversations to help me sound like a real person, or should I be focusing more on colloquial postpositions?
