Knowji
Pros
- + Methodologically sound design in its lifetime: spaced repetition with visual, auditory and contextual mnemonics per word
- + One-time pack purchases ($3.99–$11.99 historically) instead of subscriptions, per directory records
- + Offline study after initial download, with progress and memorisation-prediction tracking
- + Content organised from elementary to graduate level with SAT/GRE/TOEFL and ESL packs
Cons
- - The company has closed: knowji.com is a parked domain as of 23 October 2026 and the official X account announced the shutdown
- - Orphaned App Store listings remain installable with no backend, no updates and no support
- - No pricing exists to quote — aggregator pages listing current Knowji subscriptions are stale scrapes
- - Coverage was primarily English vocabulary with no conversational practice
- - Learning data cannot be exported or recovered through any vendor channel now that the company is gone
Brainscape AI Flashcards
Pros
- + Confidence-Based Repetition is perceptibly better tuned than binary spaced repetition — in my two-week block, interval behaviour tracked my actual recall
- + AI deck generation turns dense notes into a clean 20-card deck in under a minute in my test; free tier includes hundreds of AI-generated cards
- + Genuinely free self-study: unlimited manual creation and studying of your own cards forever, no ads
- + Certified expert-curated decks are noticeably cleaner and better organised than user decks in my comparison on exam subjects
- + Web Pro at $7.99/month (annual billing) is fair for the depth of engine and library on offer
Cons
- - Text-to-speech, promised for 2025, had still not shipped as of December 2025 App Store reviews — a real gap for language learners
- - iOS in-app Pro costs $19.99/month versus $7.99/month on the web for the same product; subscribing through Apple is a bad deal
- - Studying Certified and other users' public decks is Pro-only, so 'free forever' does not cover the library
- - No PDF/PowerPoint course import and no images or audio on free-tier cards
- - Certified coverage is uneven outside popular subjects; niche topics leave you with variable-quality user decks
