Khanmigo - Pros & Cons
Pros
- ✓Free for all teachers worldwide—a rare offering compared to paid edtech AI tools that typically charge $10-30/month per educator
- ✓Socratic methodology guides learners to discover answers independently rather than providing solutions, building genuine critical thinking skills
