Who translate5 is best for
Language service providers
User-based and volume-based licenses, a client portal and Plunet and GroupShare connections suit agencies that manage linguists and client projects.
Teams translating layout-heavy documents
translate5 Visual shows a live preview of source, pivot and target documents that updates as linguists type, which helps with brochures and structured files.
Organizations with their own MT and LLM resources
InstantTranslate and the client portal use the organization's own TM, MT and LLM resources, and on-premises LLM use is possible.

What translate5 does
- translate5 Visual
- A layout-faithful live preview of source, pivot and target documents updates as the linguist types, so formatting problems show before delivery. This helps linguists catch formatting errors before the document is returned.
- translate5 AI
- LLMs handle pre-translation, post-editing and translation quality estimation, and the page names LLM and RAG for AI translation, with on-premises LLMs possible. The vendor lists this item among the features missing from the cheapest user plan.
- InstantTranslate and portal
- Instant text or file translation runs on the organization's own TM, MT and LLM resources, and a client portal lets customers submit work. Customers can submit text or files themselves, which reduces project manager intake work.
- TermPortal
- Terminology comes with attributes, images, TBX import and export and approval workflows, which serves teams that manage controlled vocabularies. Approval workflows let a terminologist control which entries translators may use.
- API and plug-ins
- A REST API and plug-in system expose every UI function, and the t5Connect connector gives Visual Review for Across. Teams can automate repetitive steps through the API instead of repeating them in the interface.
How translate5 handles your data
The imprint says storage is tied to statutory retention periods and data is routinely deleted after that period. Cloud hosting is offered for all plans and on-premises deployment is optional, but the hosting provider is not named and no region is given. No certification is named on the pages we read, and the pages do not address whether customer content trains models. Because LLM use can be on-premises, a buyer with strict rules can keep content on its own servers, but should confirm in writing which engines run where.
Where translate5 falls short in practice
- Basic plan leaves out AI. The €2,400 plan excludes translate5 AI, TermPortal, Visual and API use, so a team that wants LLM pre-translation needs the €4,440 plan or the volume plan.
- Connectors cost extra. Plunet and GroupShare integrations are charged separately from the license, which matters for agencies whose project management runs in those systems. The vendor does not state those add-on prices on the page we read.
- Aimed at linguists. The product is organized around documents, TM and terminology, so a team shipping app strings through Git has less to gain than a language department.

translate5: common questions
How much does translate5 cost?
The user-based plan is €2,400 a year for one main user and ten linguists, the all-features version is €4,440 a year and the volume-based plan is €10,900 a year for 2,000,000 words. Flatrate pricing is by quote. There is no free plan.
Does translate5 include AI translation?
translate5 AI uses LLMs for pre-translation, post-editing and quality estimation, and it is included in the all-features and volume plans. The €2,400 basic user plan excludes it. The page also says on-premises LLM use is possible for teams that want to keep content in-house.
What is translate5 Visual?
Visual is a layout-faithful live preview of source, pivot and target documents that updates as linguists type. It is excluded from the €2,400 basic plan. Teams working on formatted files should test it on one real document before choosing a license tier.
Which systems does translate5 connect to?
The pages name Across through t5Connect, Plunet and GroupShare, plus DeepL, Google Translate and LLMs, with a REST API and plug-in system. Plunet and GroupShare integrations are charged separately, so ask for their price before signing a license. The vendor lists no price for connectors on the pages we read.
Where does translate5 host data?
Cloud hosting is offered for all plans and on-premises deployment is optional, but the pages we read name no hosting provider or region. The imprint ties storage to statutory retention periods. Ask which provider hosts the cloud service if residency matters to you.
