Overview

DeepL supports 100 languages and combines translation with translation memory, glossary tools, and website and document translation. Its browser extensions add translation and writing improvements in Chrome, Firefox, and Edge; desktop and mobile apps give individual users other ways to work. Integrations with Microsoft Word, Google Workspace, Microsoft 365, and AI agents help it fit into established workflows.

The API is the stronger reason for developers to consider DeepL: it supports building multilingual experiences and integrating Language AI into other systems. DeepL was founded in 2017 and is headquartered in Cologne, Germany.

Key features

Terminology and document workflows

Translation memory and glossaries suit repeated work where terminology needs to remain consistent. Glossary capacity varies sharply by plan: Free and Individual allow one glossary, Team allows five, and Business and Enterprise offer unlimited glossaries. Free also limits users to five glossary entries per language pair, so it is best for light terminology needs rather than maintaining a substantial shared vocabulary.

File allowances are a more immediate constraint for many users. Free permits one translation per month and files up to 5 MB; Individual raises that to three files and 30 MB. Team includes 20 file translations per month and 30 MB files, while Business offers 100 file translations monthly and Enterprise uses custom quotas. Teams can share a total file allowance or assign the same number of files to each member.

Integrations, administration, and security

Team includes administration; Business and Enterprise users can also access team administration. Single sign-on is available for Team, Business, and Enterprise, with thresholds shown for Team and Business. These controls make the higher tiers more relevant to organizations managing access centrally than to individuals choosing a translation tool.

DeepL cites ISO 27001 and SOC 2 Type II certified processes and infrastructure, and lists TLS encryption. For Pro subscribers, content and results are stored temporarily only as technically needed and then deleted. DeepL says it is trusted by over 200,000 businesses globally. Support resources include a Help Center, community, API documentation, and premium support for Enterprise.

Pricing

DeepL uses a freemium model. The free plan is $0.00 USD per free and includes 50,000 characters per user per month, one file translation per month with a 5 MB file cap, one glossary with five entries per language pair, and no stated saved translations. It is a reasonable fit for occasional translation, but its low file and glossary limits leave little room for sustained document work.

Individual costs 7.49 EUR per month, billed annually, and is free for 30 days; users can cancel anytime. It includes 300,000 characters per month, three monthly file translations up to 30 MB, one glossary, and one saved translation. This is the personal upgrade for users who need a higher character allowance and larger files, though the monthly document quota remains modest.

Team costs 24.99 EUR per month, billed annually, with a 30-day free trial and cancellation anytime. It provides 1,000,000 characters per user per month, 20 file translations per month up to 30 MB, five glossaries, and 10 saved translations. The higher character allowance and team-oriented controls make it a better fit for shared workflows, although its file quota is still finite.

Business costs 49.99 EUR per month, billed annually, and includes 100 file translations per month, 20 shared style rule lists, unlimited glossaries and saved translations, and 99.0% availability. Its greater document capacity and terminology controls suit organizations with regular translation needs. Enterprise has custom pricing with custom files per month, unlimited shared style rule lists and glossaries, and 99.9% availability; it is the option for organizations needing a tailored quota and higher stated availability.

Platforms

DeepL is available through API access and browser extensions, as well as desktop and mobile apps. The extensions work in Chrome, Firefox, and Edge. Word, Google Workspace, Microsoft 365, and AI-agent integrations provide routes into existing work environments, while the API supports developers embedding multilingual capabilities into systems.

Who it's for

DeepL is a strong fit for individuals and teams translating repeatedly across documents and work systems, especially when terminology consistency or API integration matters. Free suits occasional users; Individual suits a single user with moderate monthly needs; Team and Business better serve shared or higher-volume work. It is less compelling for users who need frequent file translation but do not want to pay for a plan with a larger quota.

Pros and cons

Pros: Supports 100 languages and combines text, document, and website translation with translation memory and glossaries, supporting recurring workflows rather than isolated lookups.
Pros: API access and integrations with Word, Google Workspace, Microsoft 365, and AI agents give developers and teams ways to fit translation into existing systems.
Pros: Higher plans add team administration, single sign-on, shared style rule lists, and greater file allowances, addressing organizational workflow needs.
Cons: Free allows only one file translation per month, caps files at 5 MB, and limits glossaries to five entries per language pair, restricting regular document and terminology work.
Cons: Individual costs 7.49 EUR per month billed annually and still allows only three file translations monthly, so frequent document users need to consider a higher tier.
Cons: Business and Enterprise availability figures are 99.0% and 99.9% respectively; organizations with uptime requirements should weigh the tier-specific difference.

Alternatives

For a broader comparison, see AI Translation Tools, Translation Software, Writing Style Checkers, and AI writing assistants. Consider Trinka as another freemium option. Revise is another freemium option with API, self-hosted, and web platforms. Sapling is another freemium option, with API, extension, self-hosted, web, and Windows platforms. StyleMCP offers a free plan with 5,000 requests per month and API access. textlint is free software for readers considering an alternative in that category. Lingofy is a paid alternative with annual subscription plans. Markup AI has paid plans starting at 249.00 USD per month, billed with annual discount, and includes unlimited users on Starter. StyleGuard is another paid alternative.

Verdict

Choose DeepL if your individual or team workflow needs translation across languages, documents, and connected tools, and if glossaries or API access will be used repeatedly. Its main advantage is the combination of translation features with integration and team options; its main drawback is that file quotas make the free and lower-cost tiers restrictive for regular document work.
