Our verdict on Doc3
Doc3 is browser-based translation and computer-assisted translation software for professional translators and translation editors. Its focus is uploaded documents: it combines automatic machine translation and AI translation with a CAT editor for review, translation memory, glossary management, and real-time quality assurance. Solo users working through document translation and review are a natural fit, while teams seeking a broader translation workflow may want to compare its document-centered scope with alternatives.
The freemium structure gives buyers a limited free plan, while Doc3 Unlimited costs $15 per month, billed monthly. That tier adds unlimited words per file and unlimited projects, alongside direct translation among hundreds of language combinations, whole-file automatic translation, quality assurance with style guides, and private cloud space. Doc3 Limited also includes document translation, QA, cloud space, translation memory, and glossary management; the published plan details do not specify numeric limits for that tier. Buyers should compare the free plan against their expected document and project needs before deciding whether the paid tier fits.
Integration options include API connectors for DeepL, Google, and Microsoft/Bing translation services, and the software supports Trados, memoQ, Microsoft Office, and OpenOffice formats. This can suit translators whose work involves those formats or translation engines, but only three translation-service integrations are named. Doc3 runs in a browser and provides cloud storage for projects and translation resources; support is available by email and documentation, and the listed compliance posture includes GDPR. Choose Doc3 for document translation and review with CAT tools; consider alternatives if your work depends on a desktop application or a wider range of named translation-service connections.
