Reverso
Pros
- + Contextual dictionary returned subtitle and official-document usage examples that resolved a Spanish false-friend in seconds in my testing
- + Free neural translation needs no account, with 2,500 free document-translation credits to evaluate the document pipeline
- + Premium lifts text requests to 8,000 characters at once and covers the whole suite (translate, correct, rephrase, learn) under one subscription
- + Document translation preserved headings and tables in a formatted Word file in my test, up to 100-page PDFs on Premium and 250 on Pro
- + iOS app (15.3+) can be set as the system default translator on iOS 18.4+, which I found faster than copy-paste workflows
Cons
- - Translation quality drops on rare language pairs and specialized technical content, where the example corpus thins out at the same time
- - Free tier caps are conservative and the interface pushes Premium hard; serious document volume needs Pro at 239.88 EUR/year
- - Large document processing lagged noticeably on a 60-page PDF versus dedicated CAT tooling
- - No translation memory, project management, or segment QA — it is a reference and translation suite, not a professional translation environment
- - LLM-based translation with custom context is announced in Reverso's MT Summit paper but was not live in my testing
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
