Overview
DeepL is an AI platform for translation and communication across languages. Its main tool, DeepL Translator, translates texts and files and supports Brazilian Portuguese. It is useful for understanding content in another language, preparing messages for people in other countries and producing a first draft of translated documents.
If you translate regularly, glossaries let you define how technical terms, product names or recurring expressions should appear in the target language. Browser access suits occasional tasks. Apps and extensions help bring translation into everyday work, while the API serves those who need to connect the service to a system.
The DeepL family also includes Write, for correcting and rephrasing written text, and Voice, for spoken communication across languages. These products have their own features, language coverage and access conditions. Check what is included in your chosen subscription. Before using the output, pay particular attention to passages where context, terminology or a mistake could have significant consequences.
Features and functionality
- Text translation: translates words, messages and passages between the available languages, including Brazilian Portuguese.
- File translation: processes documents such as PDF, Word and PowerPoint files, preserving formatting where possible. Supported formats, file sizes and the number of files depend on the service option.
- Glossaries: let you set preferred translations for terms and keep terminology consistent. Availability varies by language and plan.
- Writing improvement with DeepL Write: corrects grammar, spelling and punctuation and suggests alternative phrasing, including in Brazilian Portuguese. Access to Write Pro depends on what the plan includes.
- API: provides programmatic integration for translating texts and documents, with a subscription separate from Translator.
Use cases
- Read articles, messages and reference materials in another language.
- Prepare an initial translation of work emails and documents for review before sending them.
- Standardise product or professional terminology with glossaries.
- Improve a text with Write, preserving its intended meaning and checking the suggestions.
- Add translation to an application or workflow through the API.
How to use
- Open DeepL Translator and choose the source and target languages.
- Paste text without personal data or confidential content if you are using the free service. For files, sign in to an account and check the supported formats and limits.
- Read the translation alongside the original. Adjust important terms and use a glossary when it is available for the language pair.
- Review the result before copying, downloading or sending it. For documents, also check the formatting.
Required experience level
Browser-based translation is accessible to beginners. Glossaries and document review require attention to terminology. The API requires technical setup and code integration.
Integrations
DeepL offers apps for Windows, macOS, Android and iOS, as well as extensions for Chrome, Firefox and Edge. It also integrates with Google Workspace and Microsoft tools and offers an API for custom systems. Check the product, language and subscription required by your chosen integration.
Plans and access
Translator offers free access and paid subscriptions for individuals, teams and organisations. Plans differ in text and file limits, glossaries and management features. Free trials and commercial terms may vary by market.
The API has its own plans and does not automatically provide Pro benefits in the web translator or apps. Write Pro may be an add-on or part of a bundle. Check what the subscription includes before signing up.
With its free services, DeepL may use submitted content to train and improve its systems. The free service terms do not allow texts containing personal data or confidential information. Pro options have different data handling conditions. Check your subscription and your organisation's requirements before submitting sensitive material.
