Khan Academy's lesson videos are built for kids who can already read captions, navigate menus, and follow along with a lecture. If your child is 4, 5, or 6 and still learning their letters, that's a wall before the learning even starts.

That's a reasonable assumption for a 10-year-old. It's not a reasonable assumption for a 4-year-old who is still learning to sound out three-letter words. If you've tried sitting a pre-reader in front of Khan Academy and watched them get lost in the menus before the lesson even starts, the problem isn't your kid — it's the format.
Khan Academy narrates its instructional videos, but the surrounding site — menus, unit titles, question text, answer choices — is all text your child has to read to navigate. Lumi's lessons are voice-narrated end to end: Lumi (the app's character) reads the question, reads the answer choices, and reads the feedback out loud, so a child who can't yet read independently can still complete a full lesson on their own.
Khan Academy's own course structure realistically starts making sense once a child is reading independently, typically around 1st grade. Lumi's early lessons are designed to work for children as young as about 4, using narration and tap-to-answer interactions instead of assuming reading fluency.
A pre-reader can't type a math answer they can't read the prompt for. Lumi's early lessons use large tap targets and read the choices aloud, so the child's job is to listen and tap — not decode text under time pressure.
Khan Academy doesn't include an early-reading/phonics track. Lumi's ELA curriculum starts at the letter-sounds level, so a non-reader has an actual path toward the reading skill that Khan Academy's format quietly requires them to already have.
Some families work around Khan Academy's reading requirement by having a parent read every question aloud. That's a real solution, but it means the platform doesn't actually run independently for a pre-reader. With narration built in, Lumi is designed so a young child can sit down and work through a lesson without a parent reading the screen to them in real time.

Try Lumi Free →To be fair to Khan Academy: for a child who already reads confidently, its video library is deep and well made, and it's free. The gap only shows up at the youngest end of the age range, where the entire interaction model assumes a reader who can navigate text independently. If your child falls in that gap — old enough for real instruction, too young to read the instructions — that's specifically the age band Lumi's narration was built to serve.
This isn't a case for throwing Khan Academy out. Once your child is reading fluently, its video explanations remain a solid free supplement for math and science. The honest recommendation is to start younger kids on a narrated curriculum built for pre-readers, and layer in Khan Academy later once reading is no longer the bottleneck to using it.
Lumi's narrated lessons are designed to work for children as young as about 4, since the app reads questions and answer choices aloud rather than requiring the child to read them.
Khan Academy's instructional videos are narrated, but the surrounding site (menus, question text, answer choices) is text-based and generally requires the user to read to navigate, which is a real barrier for pre-readers.
Reading is taught within Lumi's ELA curriculum alongside narration, so the goal is for the child to grow into independent reading over time rather than being blocked by it from day one.
Lumi narrates lessons across math, ELA, science, and social studies, so a pre-reader isn't limited to one narrated subject while the rest of their schoolwork requires reading.
Yes — many families use Lumi as the core, narrated curriculum for younger kids and add Khan Academy's free video library later as a supplemental resource once reading is no longer a barrier.
