About LearnBySlides

Last updated: 30 September 2026

LearnBySlides publishes free, accurate lesson slide decks that anyone can use to learn or teach. Each deck is a complete, ready-to-teach lesson with slides, speaker notes, key terms and a short quiz, built for school curricula (starting with CBSE Classes 6–12), competitive exams and evergreen topics, for learners worldwide.

Why we exist

Good explanations are often locked behind paywalls, buried in long textbooks or scattered across unreliable pages. We want teachers, students and curious readers to have a trustworthy starting point that is free to use and easy to share. That is why every resource lists its sources, shows when it was last reviewed and carries an open license.

Who runs LearnBySlides

LearnBySlides is an independent educational project based in India. It is funded by advertising: we do not sell subscriptions, we do not ask you to create an account and we never sell personal data. Our sister site, InfoGraphHub, follows the same principles.

How we make lesson slide decks

• We pick topics people genuinely search for and teachers actually need.
• We draft with the help of AI tools, then a human reviews every fact against at least two reliable sources.
• We draw every graphic ourselves. We never copy textbook figures or stock images.
• We record who reviewed each slide deck and when, and we fix reported errors quickly.
