Readlang
Pros
- + One-click inline word and phrase translation kept my place in both a Spanish article and a French novel excerpt — no modal, no side panel
- + Flashcard queue prioritizes high-frequency words via frequency lists and spaced repetition; in my week of use it drilled reusable vocabulary, not one-off nouns
- + Premium at $48/year removes the free plan's 10-phrase/day and 200-word flashcard caps and is one of the smallest annual fees in the category
- + One subscription covers all supported languages (40+ listed), so studying two languages in parallel costs nothing extra
- + Import flexibility: browser extension and bookmarklet for any web page, plus paste/file upload for books and documents
Cons
- - Free plan phrase translations cap at 6 words per phrase and 10 per day — I hit the cap within twenty minutes of reading, and idioms get chopped up
- - No speaking or conversation practice, no grammar course, no CEFR curriculum: it is a reading tool, not a complete language program
- - Audio storage is paid-only (10 hours Premium, 200 Premium Plus; zero on free) and the TTS quality tier is gated behind subscription
- - Indie-scale support: no SLA, no phone support, no admin controls or institutional plan for schools or procurement
- - Feature discoverability is poor — the writing-practice tool only surfaced when I read the features page
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
