Machine Translation & Post-Editing

Machine translation post-editing (MTPE) is AI-powered translation refined by professional human editors—combining machine speed with human accuracy to balance cost, speed, and quality under the ISO 18587 standard.

Why Hansem?

Off-the-shelf AI expects clean, standardized input. Hansem Labs, our in-house R&D team, builds tooling that adapts AI and machine translation to your documents—however non-standard.

Purpose-Built Quality Assurance

Our own QA tool automatically catches the language errors—terminology, consistency, nuance—that conventional tools miss.

Tools That Fit Your Workflow

Use memoQ or Trados? Our in-house plugins bring the latest LLMs into your environment. Or let us run it end to end on our own AI translation and quality-evaluation platform.

Human-Accountable, Standards-Governed

Certified PMs and linguists run every project under ISO 17100 and ISO 18587—AI for speed, people for accountability.

What MTPE Delivers for You

When raw AI output isn't safe to ship

You can generate a translation in seconds—but can you stand behind it? For manuals, contracts, and regulated content, MTPE turns fast AI output into text you can publish with confidence, with certified linguists accountable under ISO 18587.
When you're scaling AI translation, not experimenting with it

Running AI translation across dozens of languages and constant updates exposes what ad-hoc tools miss—drifting terminology, inconsistent voice, silent errors at volume. MTPE adds the quality layer that keeps AI output reliable as you scale it into production.
When the cost of a wrong word is higher than the cost of translation

In technical, legal, and safety-critical content, a single mistranslated term carries real risk—recalls, liability, rework. MTPE is how you capture AI's speed and cost savings without inheriting AI's mistakes.

Our Translation Services

Technical Document Translation

Technical documents like manuals and specifications rely on consistent, standardized terminology—which makes them well-suited to machine translation, with stable and predictable results. Our background in engineering, IT, and manufacturing ensures each translation is technically accurate and ready for production use.

Standardized terminology makes technical documents well-suited to machine translation post-editing.

Business Document Translation

Reports, emails, and proposals are produced constantly and needed fast. MTPE delivers them quickly and cost-effectively, while certified post-editing keeps the tone and accuracy your business communication depends on.

High-volume, fast-turnaround business content is well-suited to machine translation post-editing.

Scientific Papers Translation

Scientific papers demand exact technical terminology and zero tolerance for error. Our machine translation paired with certified human post-editing delivers reliable, precise results—so you can share your findings across languages quickly and with confidence.

Machine translation post-editing speeds up scientific publishing without sacrificing terminological precision.

General Document Translation

General documents—simple correspondence and routine business text—use plain, objective language that machine translation handles well. MTPE delivers fast turnaround with consistent quality across everyday content.

Straightforward, objective text is naturally suited to machine translation post-editing.

Certified Quality, Backed by Security

Every Hansem translation follows the ISO 17100 two-linguist (four-eyes) review process and is delivered under ISO 27001-certified data security. Backed by ISO 9001, 17100, 18587, and 27001 certifications, Hansem gives regulated industries a translation partner they can audit and trust.

A Human Linguist Network in 100+ Languages

Hansem connects you with native, subject-matter linguists across 100+ languages — experts who understand not just the language but your industry and local market. Sustaining a network this size takes more than headcount: with our in-house Resource Management System (RMS), we recruit, verify, and assign qualified linguists by language and specialty at scale — so the right expert is matched to your project, not just an available one. The map below shows the breadth of our global language coverage.

Frequently Asked Questions

What’s the difference between machine translation and AI translation?

Machine translation (MT) uses neural models for direct conversion; AI translation uses large language models (LLMs) that account for context and intent. AI reads more fluently, but terminology errors and hallucination remain—so ISO 18587 post-editing determines final quality.

Will my content be used to train AI models?

No. Your content stays confidential and is never used to train public AI models. Hansem runs translation through controlled, in-house tooling under ISO 27001-certified data security—so contracts, specifications, and unreleased docs never leak into open systems.

Can you post-edit AI translations we’ve already generated?

Yes. If you’ve run content through ChatGPT, DeepL, or another engine, our ISO 18587-certified linguists refine it to publication standard—fixing terminology, consistency, and the errors raw AI output tends to hide. You capture AI’s speed; we make the result safe to ship.

Can I keep using my own translation memory and CAT tools?

Yes. Our in-house AI plugins for memoQ and Trados apply the latest LLMs inside your existing environment—with your translation memory, glossaries, and style guides intact. AI speed, no tool switching.

How much can MTPE reduce cost and time?

Combined with post-editing, AI translation typically cuts time and cost by around 30–50% versus traditional human translation. Actual savings depend on document type and language pair.
