Is PAITS free like Khan Academy?

Yes. PAITS offers 10 AI course generations per month completely free — no credit card required. Khan Academy is entirely free with no generation limits but has a fixed catalogue. For exploring a wide range of STEM topics, Khan Academy is more generous; for generating courses on any topic, PAITS free tier is uniquely flexible.

Does PAITS cover more subjects than Khan Academy?

Yes. Khan Academy focuses on K-12 mathematics, science, computing, humanities, and test prep (SAT, GMAT, LSAT). PAITS can generate a course on any subject — professional topics, niche technologies, creative fields, graduate-level material — with no catalogue restriction.

Can PAITS replace Khan Academy for students?

PAITS is an excellent supplement for students who need material beyond or alongside Khan Academy. For K-12 mathematics with interactive exercises and progress tracking, Khan Academy's pedagogical design is hard to beat. PAITS is stronger for subjects, levels, and topics outside Khan Academy's catalogue.

Which is better for self-study?

Khan Academy is better for systematic, exercises-based self-study in STEM subjects — its practice problems and mastery system are exceptional. PAITS is better for quickly understanding any topic, including those outside STEM, without needing a pre-existing curriculum.

Does PAITS have math courses?

Yes. PAITS can generate mathematics courses at any level — from arithmetic to linear algebra to real analysis. However, PAITS does not include interactive practice exercises like Khan Academy's. For mathematics, PAITS is better for understanding concepts; Khan Academy is better for practicing problems.

PAITS vs Khan Academy (2026): Which Is Better?

TL;DR

PAITS — AI generates a personalized course on any topic in < 5 minutes. Free (10 courses/month).
Khan Academy — Free, non-profit STEM platform with K-12 coverage, interactive exercises, and mastery tracking. Fully free, no limits.
Best for any topic, any level: PAITS
Best for STEM practice and mastery in K-12 curriculum: Khan Academy

Introduction

Khan Academy is one of the most beloved educational platforms ever built — free, high-quality, and genuinely helpful for millions of learners. PAITS approaches education from a completely different angle: instead of a fixed curriculum, it generates a new course for any topic you describe.

Both are free. Both help you learn. The difference is in scope and depth.

Head-to-Head Comparison

Feature	PAITS	Khan Academy
Cost	Free (10/mo) · Pro $29/mo	100% free, unlimited
Subject coverage	Any topic	K-12 STEM + test prep
Interactive exercises	Inline quizzes	Extensive problem sets + hints
Mastery tracking	No	Yes (unit mastery system)
Content type	Notes + slides + video	Video + exercises + articles
Personalization	Difficulty-adaptive	Adaptive exercises
Adult learning	Strong	Limited (K-12 focus)
Professional topics	Yes	No

When PAITS Wins

Topics outside Khan Academy's catalogue. Khan Academy covers K-12 well — but not professional software development, cloud computing, finance, design, or any graduate-level subject. PAITS covers all of these.

Adult and professional learners. Khan Academy is designed primarily for school-age learners. PAITS generates content calibrated for adult professionals who want to learn new fields quickly.

Speed. A PAITS course is ready in minutes. Khan Academy requires navigating to the right unit and working through sequential content.

When Khan Academy Wins

Mathematics mastery. Khan Academy's interactive problem sets, hints, and mastery tracking for mathematics are genuinely best-in-class. For practicing maths problems, no AI-generated content replicates this.

Zero cost, zero limits. Khan Academy is 100% free with no monthly generation cap. For students who need continuous access across many subjects, this is a meaningful advantage over PAITS's 10 free generations per month.

K-12 curriculum alignment. Khan Academy tracks national curriculum standards and provides structured progressions. PAITS generates content but does not align to specific curricula.

Verdict

For K-12 STEM with interactive exercises: Khan Academy is unmatched and free. For learning any topic — professional, niche, adult-level, or beyond K-12 — PAITS fills the gap Khan Academy leaves.
