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.
Google Translate AI
Pros
- + 249 languages and varieties as of 2026 — the widest public coverage I measured against any engine
- + Free consumer product covers camera, voice, offline, documents and whole-webpage translation in one place
- + Gemini upgrade measurably improved idiom and conversational register in my informal-content tests
- + Cloud Translation API has a genuine free tier (500,000 chars/month) and per-character pricing that starts at $20 per million characters for NMT
- + Camera and offline translation are genuinely field-usable — I rely on them while travelling
Cons
- - Quality trails DeepL on formal European business prose in my side-by-side runs
- - Low-resource pairs are gist-only despite the 249-language headline
- - No glossaries, translation memory, review workflows or terminology enforcement
- - Privacy terms on the free consumer product are a non-starter for confidential content
- - Complex PDF and layout-heavy document translation frequently scrambles formatting
