Compare the same subject and level before choosing. Khan Academy's free core library and Brilliant's daily keys offer ways to inspect the material without assuming a paid plan is necessary.

The decision is about content, feedback and access. This comparison has not measured which app produces better learning outcomes.

The short answer

Match the topic, level and access

Start with the course that addresses your actual gap. Khan Academy provides free core lessons and practice; Brilliant offers an interactive STEM format with limited free access and paid expansion.

Choose Khan Academy

  • Free core explanations and practice in a covered subject.
  • Official SAT preparation developed with College Board.
  • Following a relevant subject path without a core-library subscription.

Choose Brilliant

  • Interactive problems in a supported STEM subject.
  • A sample whose explanation and feedback fit your starting point.
  • More access or Koji features after checking the relevant paid plan.

Try the idea

Use the same topic to compare feedback.

Original example: solve 2x + 6 = 14. Subtract 6 from both sides, then divide by 2 to get x = 4. Substitution gives 2 × 4 + 6 = 14. Now solve 2x + 6 = 18; the answer is x = 6.

If you get stuck, identify the missing step and try a relevant lesson in each product. Compare whether its explanation helps you solve a fresh problem. This is a proposed personal fit check, not a benchmark we ran.

Before you choose

Keep core access separate from tutoring.

Khan Academy's core material is free. Khanmigo learner access has separate payment and eligibility rules; adult access currently requires US residence and billing, while younger learners use an eligible parent or school route. Teacher arrangements differ.

Brilliant's free keys can open a lesson or practice set. Premium changes access and Koji features. Its current help page says lessons cannot be downloaded for offline use.

Before you choose

Avoid a fixed foundation-then-challenge rule.

Both products contain material at different levels. A beginner may find a suitable Brilliant lesson; an advanced learner may find relevant Khan Academy material. Inspect prerequisites and the actual task.

Use both only if they serve distinct needs. More apps and parallel streaks do not by themselves demonstrate progress.
