How do I terminate my Doc3 account or request cancellation by email?

To terminate your account (free or paid) by email, send a notice to notify@doc3.com stating your user-ID and clearly in English that you want to cancel your account and/or subscription. Download private data before termination; data is deleted after a retention period as stated in the terms.

What happens to my projects and data after cancellation?

Your access remains active until the end of the paid period. After termination, Doc3 deletes user data after the stated retention window, so export your files, memories, and glossaries before cancelling.

Doc3™ introduces major upgrade: Near-perfect AI translation of documents with fast editing

Doc3™ now offers a major update that brings near-perfect AI translation of documents together with rapid editing tools and other new features. The new release is designed both for people who only translate occasionally at work and for professional translators who want AI speed combined with a CAT tool for precise fine-tuning.

Simple mode: full-auto AI translation of documents in a few clicks

The new Simple mode focuses on translating complete files with minimal effort. Users choose the source and target languages, optionally name the project, add their files, and run the translation. Within moments, Doc3™ produces a clean, ready-to-download document in the original format. All common formats are supported, including MS Office or OpenOffice, but also Trados and memoQ files.

Once the translation is ready, users can also open it directly in the Doc3™ translation editor, if any edits are necessary. Every segment can be reviewed and adjusted with real-time spellcheck and translation quality control. After editing, the updated file is saved and exported instantly.

Doc3 AI Translation & CAT tool

Easy switch between Simple mode and the advanced CAT tool environment

A key advantage of Doc3™ is the smooth transition between quick AI translation and full CAT editing. With one setting switch, users can jump from Simple mode into the complete CAT environment and back again. This workflow flexibility is something competing tools such as DeepL do not provide to this extent.

DeepL translates whole files but does not offer integrated editing or a native CAT tool. Doc3™ covers both steps — instant AI translation of entire documents and seamless editing in a proper CAT interface — in a single platform.

Advanced mode for professional translation workflows

For those who need more control, Advanced mode unlocks extended professional features. Translators can work with translation memories, glossaries, fuzzy match statistics, and private Doc3™ cloud storage.

You can also select from different machine translation engines and enable CrossCheck, the built-in quality assurance tool. When you switch back to Simple mode, all advanced options are tucked away again for a clean, streamlined interface.

Doc3 full auto mode

Unlimited translation volume

The Doc3™ Unlimited subscription removes all limits on project size and file volume. Unlike the free Limited plan with its 300-word cap per file, Unlimited allows users to translate any number of files, of any length, across hundreds of languages. All previous projects remain accessible in project history, which is ideal for users who manage several assignments in parallel.

One integrated workflow for AI translation and editing

With this update, Doc3™ now offers one of the most efficient end-to-end translation workflows available. Entire documents are translated automatically in any language pair, and users can edit everything immediately in the CAT tool. All projects stay saved, ready to reopen at any moment.

Doc3™ stands out as the most affordable AI-powered translation and CAT solution with native support for formats such as Trados and memoQ — and it is available to try for free.
