Where Khan Academy Wins
Content Library
Khan Academy has over 15 years of content. Thousands of video lessons covering math, science, history, economics, computing, and more. If you want a structured, video-based learning path, nothing beats the sheer volume of Khan's library.
Proven Track Record
Khan Academy is used by millions of students and has extensive research backing its effectiveness. It's a known quantity. Your child's school may already use it.
Price
The free tier is incredibly generous. You get the full content library, exercises, and progress tracking for $0. Khanmigo (the AI assistant) adds conversational tutoring for $44/year — still very affordable.
Structure
Khan's learning paths are meticulously organized. If you want a "just follow the path" experience, Khan Academy delivers that better than almost anyone.
Where Trellis Wins
Conversational Learning
Trellis is built around conversation, not videos. Your child talks to the AI (text or voice), asks questions, gets explanations, and works through problems interactively. It feels like having a patient tutor, not watching a lecture.
This matters because many kids — especially those with ADHD — can't sit through a 10-minute video. A conversation adapts to their pace, attention, and questions in real time.
Voice and Camera Input
Trellis lets students speak their questions and photograph their handwritten work. For younger kids who can't type well, and for any student who thinks better with a pencil, these input modes remove friction that Khan's text-only AI can't.
Multi-Curriculum Support
If you're following a UK curriculum (GCSE, A-Levels), IB, or IGCSE, Khan Academy's content has gaps. It's primarily built around US educational standards. Trellis supports multiple curriculum frameworks from the start.
ADHD/Neurodiverse Design
Trellis is explicitly designed for neurodiverse learners. Short sessions, flexible pacing, multiple input modes, and no long passive videos. Khan Academy works for many ADHD students, but it wasn't designed with them as the primary audience.
Three Integrated Modes
Trellis offers Study (learn concepts), Test (practice under timed pressure), and Practice (guided problem-solving) in one integrated experience. Khan Academy has similar elements, but they feel more separate.
When to Choose Khan Academy
- You want a massive, proven content library
- Your child learns well from video instruction
- You're following US curriculum standards
- Budget is the top priority (the free tier is excellent)
- You want structured, sequential learning paths
When to Choose Trellis
- Your child learns better through conversation than videos
- Voice or camera input would reduce friction
- Your child has ADHD or other learning differences
- You're following UK, IB, or international curricula
- You want a single adaptive tutor across all subjects
Can You Use Both?
Absolutely. Many families use Khan Academy for its structured content library and Trellis for its conversational tutoring and adaptive practice. They complement each other well. Use Khan's videos to introduce a topic, then use Trellis for practice and deeper understanding.
The Bottom Line
Khan Academy is the safe, proven choice. It's free, massive, and works well for most students. Trellis is the innovative choice — more natural, more adaptive, and better for kids who need something different from the standard video + exercise format.
Neither is objectively "better." The right choice depends on your child.
