MateCat
Pros
- + Truly free with unlimited users, projects and storage — no word meter at all, unlike Smartcat's 15,000-Smartword monthly cap on free AI translation.
- + ModernMT adaptive machine translation is the default engine for logged-in users at no cost, learns from your edits in real time, and carries a 100,000-word context window across 200 languages.
- + MyMemory — around 12 billion words of public translation memory — is preloaded, giving fuzzy-match coverage from the first segment.
- + Zero-friction access: single files translate with no registration at all, entirely in the browser, across 80 file formats with the format preserved on download (documented exceptions for iWorks and PDF).
- + Open source under the LGPL and self-hostable, with a REST API (projects up to 600 files at 200 MB each), open standards (XLIFF, TMX) and open APIs for external TMS and MT connections.
Cons
- - Vendor documentation contradicts itself on fundamentals — 70 vs 80 vs 82 file formats and 90 vs 200+ languages across its own pages — which makes pre-purchase verification unnecessarily manual.
- - On the hosted service, source files, segments, translation memories and outputs all live on Translated's servers; self-hosting means a manual Ubuntu install with no maintained cloud image.
- - The MT features that matter most for production shops — glossary enforcement in MT, pretranslation adaptivity, TM optimisation — are gated behind paid ModernMT licences.
- - Thin translation-management layer: no linguist marketplace, limited workflow and permission controls, and collaboration described as basic by independent comparisons.
- - Single-vendor dependence: development and hosting rest with Translated srl, whose business model is translation outsourcing and ModernMT licences — free support has no SLA and no paid tier exists to buy one.
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
