More on this

Knowt and Quizlet start from the same idea: flashcards plus practice tests. Knowt grew up as a free alternative. Its Basic plan is free, its site says flashcards and the learn mode are not locked behind a paywall, and it can import your existing Quizlet sets in one click.

Quizlet has the bigger name and a very large library of sets made by other students, with study modes such as Learn, Test and Match. On its free plan some tools are capped, and Plus is a subscription. Both now use AI to turn notes or files into study material.

Paid prices differ a lot, and both sites change them, so compare the plans on each site before you subscribe. As of October 2026, Knowt Ultra is $24.99 a month or $149.99 billed yearly.
