Use Khan Academy if you're starting from scratch or need foundational math (K–12, pre-calculus, SAT prep). Use Brilliant if you're already strong in math and want engaging, advanced problem-solving and logic puzzles. Khan excels at building basics; Brilliant excels at deepening advanced skills. Both offer free trials—try both for 7–14 days to see which fits your pace.
Khan Academy is completely free for all core courses and practice exercises. Brilliant offers limited free content (puzzle previews only); most content requires a Premium subscription (~$12/month in 2026). For full free access to a comprehensive curriculum, Khan Academy wins. Both offer 7–14 day free trials of their premium features.
Khan Academy is definitively better for SAT/ACT prep. It has an official partnership with College Board and offers full SAT practice tests, personalized practice plans, and targeted skill building—all free. Brilliant doesn't offer formal standardized test preparation. If your goal is SAT/ACT readiness, choose Khan Academy.
It depends on your goal and learning style. Khan Academy is better for: curriculum-following (aligned to school math from Pre-K through calculus), free access, video explanations you can rewind, and tracking progress against grade-level standards. Brilliant is better for: building deep mathematical intuition, understanding WHY math works (not just how to execute procedures), adult learners who want engaging interactive problem-solving, and going beyond school math to explore number theory, probability, and advanced topics. For a student trying to pass their algebra class: Khan Academy. For an adult who wants to genuinely understand mathematics at a deeper level: Brilliant.
Yes — Khan Academy is entirely free with no premium tier, no paywalled content, and no ads. The full library of videos, exercises, and courses is available at no cost to anyone in the world. Khan Academy is a nonprofit funded primarily by major philanthropy (Bill and Melinda Gates Foundation, Google.org, Fundación La Caixa, and others). The only paid product is Khanmigo ($44/month or $44/year with school partnerships), an AI tutoring assistant built on GPT-4 that supplements the free content with interactive Socratic guidance. The core educational content remains free as part of Khan Academy's mission.
Brilliant has content for different levels but works best for adult learners with some foundation. The "Foundations" courses in math and science are designed to be accessible to absolute beginners and build from first principles with excellent visual interactives. However, Brilliant's problem-solving approach requires more active cognitive effort than Khan Academy's explanatory videos — some true beginners find it challenging without the scaffolding of a traditional explanation first. For complete beginners: Khan Academy builds foundational understanding effectively. For beginners with some math comfort who want to engage deeply with concepts: Brilliant's foundations courses are excellent.
Brilliant is a supplement or alternative learning path, not a college replacement. It can build excellent STEM intuition and cover topics that overlap with introductory college coursework (calculus, physics, probability, data structures) in more engaging ways than many textbooks or lectures. However, Brilliant has no credentialing, no official grades, no instructor feedback, and is not accredited. For professional certification or degree requirements: traditional courses or MOOCs with certificates (Coursera, edX) are appropriate. For building genuine understanding of math and science beyond what college courses develop: Brilliant is excellent. Many people use Brilliant alongside formal education to deepen their understanding.
It depends on your goal. Khan Academy is free and sufficient for K-12 curriculum support and SAT/ACT prep. Brilliant at $149.99/year is worth paying if you're an adult or advanced learner who wants to develop genuine mathematical intuition, build computational thinking skills, or learn topics like Python, data science, or quantum computing that aren't free on Khan Academy. Brilliant's interactive problem-solving approach also reduces passive learning habits — its course completion rates are significantly higher than video-only platforms. If your goal is homework help or test prep, Khan Academy is enough. If your goal is building real STEM thinking skills, Brilliant delivers measurably better outcomes for adult learners.
Expert Analysis: Khan Academy vs Brilliant
Khan Academy and Brilliant are both digital learning platforms, but they serve different learning styles and educational goals. Khan Academy is the world's largest free educational resource; Brilliant is a subscription-based platform focused on problem-solving and active learning for STEM subjects. Choosing between them depends on whether you need curriculum-aligned academic support or want to develop genuine mathematical and scientific intuition.
Khan Academy was founded by Sal Khan in 2008 and has grown to serve over 150 million registered learners in 50 languages as of 2026. It is a nonprofit funded by donations from Gates Foundation, Google, and others. Khan Academy covers K-12 math, science, computing, and humanities with video lessons, practice exercises, and progress tracking — all completely free with no subscription required. It aligns directly to US Common Core standards and offers SAT/ACT prep via a partnership with College Board. The platform's free access and curriculum alignment make it the default recommendation for students who need homework help, exam prep, or subject remediation. Khan Academy's AI tutor "Khanmigo" (powered by GPT-4) launched in 2023 and provides conversational tutoring for students and teaching tools for educators, available via a separate subscription or school licensing.
Brilliant was founded in 2012 and has grown to approximately 10 million learners with a subscription model at $24.99/month or $149.99/year ($12.50/month billed annually). Brilliant's philosophy is that the best learning comes from active problem-solving rather than passive video watching. Its courses — in math, science, computer science, and data science — are built around interactive problems, visual simulations, and guided discovery. Rather than explaining a concept and then asking you to apply it, Brilliant often presents a counterintuitive problem and walks you through discovering the principle yourself. This approach is particularly effective for developing mathematical intuition and problem-solving skills that transfer beyond specific topics. Content ranges from foundational (Pre-Algebra) through advanced (Calculus, Statistics, Neural Networks, Quantum Computing).

The practical difference: Khan Academy is better for keeping up with school curriculum, preparing for standardized tests, and free access to well-organized K-12 content. Brilliant is better for adults or advanced students who want to genuinely understand math and science at a deeper level, build computational thinking skills, or learn topics like Python programming or logic that aren't covered in Khan Academy's free tier. Brilliant's interactive approach reduces the passive consumption problem common to video-based platforms — its completion rates for full courses are notably higher than video-only platforms.
Both platforms have mobile apps and work well for self-directed learners. Neither replaces a live teacher for students who need structured accountability.
For K-12 students needing curriculum support: Khan Academy. For curious adults, advanced students, or anyone wanting to genuinely develop STEM thinking skills: Brilliant is worth the subscription cost.
