DeepL
Pros
- + Glossary enforcement held across both text and document translation in my tests — pinned terms stayed untranslated.
- + Document translation preserved DOCX tables and heading styles instead of flattening them.
- + HTML tag handling leaves markup in place and does not bill tags as characters, which keeps web-content costs predictable.
- + Free web tier (50,000 characters/month) is enough to evaluate quality on your own content before paying.
Cons
- - Free tier is small and file translation is metered separately (3 files/month on Individual).
- - DeepL Write Pro is a paid add-on on Individual and Team rather than included.
- - API overage (roughly EUR 22 per million characters at time of writing) prices higher than Google's basic tier.
- - Still fewer low-resource language pairs than Google Translate despite the 100+ language expansion.
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
