The three biggest names in flashcards, compared head to head. Anki has the best algorithm but the worst UX. Quizlet has the best UX but no real spaced repetition. Forgetless combines the algorithm from Anki with AI-powered card creation — at half the price of Quizlet Plus.

If you need FSRS v6 spaced repetition and want to create cards fast, Forgetless is the best option. You get Anki's algorithm with a modern UI and AI card generation. Upload your lecture PDFs or paste YouTube links and get study-ready decks in seconds. No plugin installation, no manual configuration.
If you just want to make some flashcards and quiz yourself before an exam, all three work. Quizlet is the most familiar if you've used it in school. But if you want to actually retain the material long-term, Quizlet's lack of spaced repetition means you'll forget most of it within weeks. Forgetless gives you real retention scheduling without the complexity of Anki.
If you already have a massive Anki collection with custom note types and advanced templates, Anki is hard to replace. Forgetless doesn't support Anki's template system. But if your main frustration is the time it takes to create cards, Forgetless's AI generation can save you hours per week. Many users run both — Anki for existing decks, Forgetless for new material.
Anki dominates language learning with community-shared decks. Quizlet has vocabulary sets but no real retention algorithm. Forgetless lets you paste a YouTube video in your target language and auto-generate vocabulary flashcards from the transcript — a workflow neither Anki nor Quizlet supports.
The biggest friction in spaced repetition is making the cards. Anki requires manual entry for every card. Quizlet makes it slightly easier but still manual. Forgetless removes the bottleneck entirely — describe a topic, paste a YouTube link, or upload a PDF, and AI generates your deck in seconds. The time you save on card creation means you can actually spend your time studying.
