Choose Duolingo if...
Duolingo is ideal for casual beginners looking to build basic vocabulary and establish a daily learning habit, but insufficient for those seeking conversational fluency or deep grammatical understanding. Serious learners should use it as a supplementary drill tool rather than their primary education source, while free users must tolerate increasingly restrictive energy limits.
Choose Khan Academy if...
Khan Academy is essential for any student needing homework help, homeschoolers seeking structured curriculum, or adults refreshing forgotten skills—offering legitimate educational value that rivals expensive tutoring. However, mobile users should expect occasional technical frustrations and may prefer the desktop website for complex coursework or reliable offline access.
