DeepL Write is an AI-powered writing assistant that enhances text quality by suggesting improvements, synonyms, and style adjustments, helping users create clear and effective content.
DeepL Write is an AI-powered writing assistant that enhances text quality through intelligent suggestions on grammar, word choice, phrasing, style, and tone, enabling users to communicate more effectively while preserving their original voice and intended meaning.[1][2] The tool offers real-time corrections and one-shot refinements that deliver polished, ready-to-use output in a fraction of a second, with a visual highlighting system that allows users to quickly review changes before implementation.[2]
Available in English, German, French, and Spanish, DeepL Write supports multiple writing styles—including business, academic, and casual—and caters to diverse use cases ranging from internal messages and emails to contracts and pitch decks.[1][4] The tool is designed for both individuals and teams who need to communicate in languages where they may lack full proficiency, as well as native speakers seeking to perfect their writing and maintain consistent brand voice.[4][5]
What distinguishes DeepL Write is its foundation in DeepL's proprietary large language models, which prioritize linguistic nuance and context awareness while minimizing hallucinations, combined with its emphasis on augmenting human creativity rather than replacing it.[2][5] Enterprise users benefit from comprehensive security features including TLS encryption, ISO 27001-certified data centers, and strict data privacy policies ensuring that user content is never stored, shared with third parties, or used for model training.[1]

High risk across multiple dimensions. Only use with public, non-sensitive data.
DeepL explicitly reserves the right to use Free Services content to train and improve neural networks and algorithms, with no opt-out mechanism for free tier users. This is a clear high-risk scenario where employee data directly feeds the training pipeline.
“[ToS] 'we reserve the right to process the content you upload (e.g., your texts and documents) and its translation/improvement for a limited period of time to train and improve our neural networks and algorithms.'”
While DeepL disclaims copyright ownership of translations, the ToS grants them broad rights to process, store, and use submitted content for training purposes without explicit restrictions on sublicensing or derivative use. The license scope is effectively perpetual for training purposes.
“[ToS] 'we reserve the right to process the content you upload...and its translation/improvement for a limited period of time to train and improve our neural networks and algorithms.'”
DeepL states they transfer content to third-party servers (data processors) with DPAs in place, which provides some protection. However, the language is vague about which third parties and the scope of 'service provision' is not clearly defined.
“[ToS] 'We reserve the right to transfer your content to servers of third parties in order to provide our services. These third parties are our data processors and we have concluded a data processing agreement with them.'”
The ToS mentions content is processed 'for a limited period of time' but does not specify exact retention periods, deletion timelines, or what happens to data used for training. The vagueness creates moderate concern about data exposure duration.
“[ToS] 'we reserve the right to process the content you upload...for a limited period of time to train and improve our neural networks and algorithms.'”
DeepL explicitly states they do not obtain or assume any copyrights to translations made by users, meaning the company retains full IP ownership of generated outputs. This is enterprise-friendly.
“[ToS] 'DeepL SE does not obtain or assume any copyrights to the translations made by you using the translation service.'”
The ToS mentions data processing agreements with third parties but does not reference SOC 2, ISO 27001, GDPR compliance certifications, or a published security/trust page. Compliance status is unclear from this document alone.
“[ToS] 'These third parties are our data processors and we have concluded a data processing agreement with them so that they may only process the data according to our instructions.'”
