Watching a lesson is not the same as having a conversation.
Khan Academy is one of the world's great educational gifts. Grove does something different: it actively develops how your child thinks, not just what they know.
The Research Gap
Passive video learning has a retention problem.
Studies consistently show that active dialogue produces significantly higher retention and deeper understanding than passive video. Khan Academy videos are excellent. But talking through an idea with an AI that knows your child produces different outcomes than watching someone else explain it.

Active vs. passive learning
Conversation beats lecture
The Socratic method has 2,400 years of evidence behind it. When children articulate their own understanding — in real time, with a responsive partner — they learn more deeply. Grove is built on this principle.
It knows your child
Khan Academy gives Sal Khan's explanation to every child. Grove gives your child an explanation built around what it knows about how they think, what they already understand, and what they're ready for.
Beyond academic content
Khan Academy is designed to deliver academic knowledge. Grove is designed to develop cognitive capacity — reasoning, creativity, empathy, resilience. These are the skills that make knowledge useful.
Frequently asked questions
Is Khan Academy still free?
Yes, Khan Academy remains free for students and families. It is supported by donors and foundations, and Sal Khan's mission has always been to provide world-class education at no cost. Khanmigo, Khan Academy's AI tutoring assistant, does carry a $4/month fee, but the core video library and practice exercises on Khan Academy remain freely accessible. It's one of the most remarkable educational gifts on the internet.
How is Grove different from Khan Academy?
Khan Academy delivers academic knowledge through expert-made videos and practice problems. Grove develops cognitive capacity through personalized AI dialogue. Khan Academy is passive: your child watches and answers. Grove is active: your child talks, explores, and is guided to think more deeply. Khan Academy excels at curriculum coverage. Grove excels at building the reasoning, creativity, and intellectual curiosity that make your child a better learner across every subject — not just the ones covered in a video library.
Does Khan Academy have AI tutoring?
Yes — Khan Academy offers Khanmigo, an AI tutoring assistant powered by GPT-4. Khanmigo can guide students through homework, explain concepts in Khan Academy's curriculum, and help with essay writing. It's text-based, session-limited in memory, and costs $4/month. Grove's AI goes further in scope: it builds a longitudinal model of your child's thinking across years, works through voice, and tracks developmental growth across 12 cognitive dimensions rather than academic subjects alone.
Which is better for elementary school kids?
For elementary-age children (roughly ages 5–10), Grove is the stronger choice. Khan Academy's videos are text-heavy and better suited for independent learners in middle school and beyond. Grove is voice-first — children can talk naturally without needing to read or type — and is specifically designed to meet children where they are developmentally. Grove's conversations adapt to a 6-year-old's vocabulary and attention span in ways that a video lecture simply can't. Many families use both: Khan Academy for structured curriculum and Grove for daily cognitive development.
