What is AI & Machine Translation?
AI translation (machine translation) uses technologies such as neural machine translation (NMT) and large language models (LLMs) to translate content quickly and at scale.
AI-powered tools, when combined with human expertise, can bring significant value to specific projects – particularly for high-volume or less complex content. However, their effectiveness depends heavily on choosing the right tools and process based on the material type, context, and end goals. Our Machine Translation Post-Editing (MTPE) service pairs advanced AI output with expert human review to refine and enhance translations – ensuring they meet high AI quality standards.
For critical content – such as item text in assessments or exams, sensitive documentation (such as that required for clinical trials) or materials that require a high level of creativity (e.g., marketing materials) – our fully human translation remains the gold standard. These projects are carried out under our processes certified under ISO 17100, ensuring the highest levels of quality, accuracy, and consistency. We also offer value-added services such as back translation, dual forward translation, multilingual voice-overs, subtitling, and expert review to support precision, minimise risk, and help you avoid costly mistakes.
What Makes Our AI Translation Services Different?
AI is a tool – not a replacement. We ensure it meets high AI translation standards before anything is delivered to you.
Better Tools
We primarily use LLM-based tools (AI systems trained to understand and generate language) that can be tailored with client-specific data, style guidelines, translation memories, and glossaries when supported. We select the best engine for each project based on your content and technical requirements.
Confidentiality
Unlike free AI tools, our workflow ensures your data remains secure and private. It is used solely for completing your project – never stored, shared, or used to train AI engines. Our platforms are fully secure and designed to protect your content at every stage.
Quality That Suits You
From the start, we choose the most suitable tools for your content and apply human post-editing (MTPE) to enhance accuracy and consistency. While we can leverage existing translations and glossaries when supported, we tailor our Quality Assurance checks based on your preferences and how polished your final translation needs to be – whether that’s publication-ready or a lighter, fit-for-purpose version that conveys your message.
Flexible File Handling
We have the technical capability to handle many different file types and content structures. We ensure that the translated content is delivered back to you in the correct format, fully ready for you to upload into your systems.
When to Use AI Translation + MTPE?
Our clients typically use this workflow for:
- Collateral materials
- Report text
- Training materials
- Technical documentation and manuals
- Surveys or data collection
- Internal documentation
- Bulk content like product descriptions
- E-learning
Comms AI Translation Services
Letting us handle your AI translation from the outset is faster, more cost-effective in the long run, and allows us to ensure quality input from the beginning. If you’re using your own AI tools – especially free versions or tools that aren’t the best fit for your project – you may end up with poor-quality output. Trying to fix that during post-editing can significantly increase both costs and turnaround time.
We use advanced LLMs, carefully selected and configured based on:
- Your content type
- Language pair
- Industry and domain
- Layout and technical aspects
Our AI translation services offer:
- Rapid turnaround times
- Cost-effective processing of large volumes
- Support for a wide range of languages
- Robust data privacy and security
However, AI-generated translations almost always require human intervention. Output can contain inconsistencies, inaccuracies, layout issues – and sometimes outright mistranslations. That is why we pair AI with professional human post-editing.
MTPE: Machine Translation Post-Editing
MTPE is the process of refining AI-generated translations through expert human review.
At Comms Multilingual, we work with properly trained, specialised linguists who know what to look for in AI-generated content. Their expertise ensures that our translations are accurate, use appropriate vocabulary and style, and are fit for purpose.
We can tailor the level of editing to suit your needs – from light to full post-editing. Some clients want polished, publication-ready text with no compromise on quality; others are mainly interested in ensuring that the text is understandable and conveys the intended meaning, so a lighter review is sufficient for them. Whatever your preference, we will work with you to deliver the right outcome.
Prompt Optimisation
Modern AI translation increasingly involves large language models (LLMs).
We support:
- Prompt design and optimisation for translation outputs
- Development of AI-specific style guidelines to improve consistency
- Domain-specific tuning of AI models
- Structured workflows for ancillary content (e.g. UI text, instructions, supporting materials)
These approaches help make AI-generated content more context-aware, consistent, and aligned with your terminology and purpose. However, outcomes are not uniform across all languages – some languages do respond better to prompt optimisation than others, and results can vary depending on linguistic complexity and available training data.
FAQ’s
Human-in-the-loop AI translation combines AI-generated translation with review and editing by professional human linguists. Rather than relying on raw AI output, a linguist checks the translation for accuracy, terminology, tone, context and suitability for its intended audience. At Comms Multilingual, human expertise is built into our AI translation and MTPE workflows, helping clients benefit from the speed and scalability of AI while maintaining professional quality control.
Machine Translation Post-Editing (MTPE) is the process of having a professional linguist review and improve a translation produced by machine translation or AI. Raw AI translation has not been professionally checked; MTPE adds human review to correct inaccuracies, improve terminology, style and fluency, and make the translation fit for purpose.
AI translation can be highly effective for the right content, particularly large volumes of relatively straightforward material, but it is not equally reliable for every language, subject or content type. AI can introduce mistranslations, inconsistencies and problems with terminology, context or tone. For this reason, we normally combine AI translation with professional human review. For high-stakes, sensitive or highly creative content, fully human translation may still be the safer choice.
AI translation with MTPE is often a good option for high-volume content such as reports, training materials, technical documentation, surveys, internal documentation, product descriptions and e-learning. Fully human translation is generally more appropriate when the content is high-stakes, highly creative or requires exceptional linguistic precision. We assess the content, language pair, audience and level of risk before recommending the most suitable translation workflow.
Security depends heavily on the tools and workflow being used. With Comms Multilingual’s managed AI translation service, your content is handled through secure professional platforms and is used only to complete your project. Our workflow is designed so that client content is not stored, shared or used to train AI engines. This makes professional AI translation very different from simply uploading confidential business information to a free public AI tool.
Yes, depending on the technology used. AI and LLM-based translation workflows can be configured using client-specific terminology, glossaries, style guidelines, translation memories and other reference material. At Comms Multilingual, we select and configure the most appropriate tools for each project and can also optimise prompts and AI-specific style guidelines to improve consistency with your preferred terminology, tone and brand voice.
Yes. If you already have translations created using ChatGPT, DeepL or another AI or machine translation tool, our professional linguists can review and post-edit them for you. This process, known as Machine Translation Post-Editing (MTPE), checks the AI-generated translation against the original content and corrects issues with accuracy, terminology, grammar, tone, style and consistency. We can provide light or full post-editing, depending on how the translation will be used. If the original AI translation is not of sufficient quality, we can also advise when retranslating from scratch would be the better option.
The cost of AI translation with human review depends on factors such as the language pair, word count, subject matter, quality of the AI-generated translation and the level of post-editing required. For suitable content, combining AI translation with professional human review can be a cost-effective way to translate large volumes of content while still maintaining quality. We assess each project individually and recommend the most appropriate workflow, whether that is AI translation with MTPE, full human translation, or a combination of the two.

Often, yes – if the content is suitable for AI translation and the initial translation is of good enough quality.
Machine Translation Post-Editing can reduce the amount of work required from a professional linguist, making it an efficient option for many high-volume translation projects. However, AI translation is not suitable for every type of content. If the initial output contains significant errors or requires extensive rewriting, post-editing may take as long as – or sometimes longer than – translating the content from scratch. That is why we assess the content and AI output first and recommend the most cost-effective approach without compromising the quality you need.
