Want to translate your content faster to reach out to a global audience? You can use a computer-assisted Translation (CAT) tool. 

The rapid growth of artificial intelligence (AI) and machine learning (ML) have made content publishing life easier than ever. Now, you can compose engaging social media copy, marketing emails, and blogs using AI tools.

But, limiting your content to English will narrow your audience to the English-speaking population, approximately 19% (1.5 billion in 8.0 billion) of the global population, according to Statista.

You are missing out on the rest of the 80% of the population. If this persuades you to think more about producing content in other leading languages, then you need a CAT tool.

And choosing the right CAT application is just a walk in the park if you read this article until the end!       

What is a Computer-Assisted Translation (CAT) Tool?

YouTube video

CAT tools assist linguists and translators in translating content from one language to another. 

It is not a machine translator like the Google Translator app. CAT software will not translate text content from one language to another with the click of a button. 

Instead, professional translators use this tool to get assistance in storing translated content for future use, organizing input content in small paragraphs, assisting in spelling, pointing out typos, and so on.

Such software also facilitates easy management of translated content by website editors and publishers. Otherwise, publishing the same content in different languages on your website could be messy.

You can also consider CAT tools a program that brings interactivity to translation and multilingual content management.

Human translators and linguists accurately extract the meaning of a paragraph from one language to the other. While the CAT tool is continuously scanning the workspace for fine errors that escape human eyes.

You will find such tools mostly in language service-providing agencies.       

Why Do You Need a CAT Tool?

#1. Fast Forward Long Term Translation Projects

When you use CAT software for long-form content translation like eBooks, knowledgebases, etc., it assists you technically in completing the project faster.  

#2. Reduce Minor Errors and Typos

CAT tools come with side by side view for translated and non-translated content. Also, it helps in proofreading, typo correction, and more. 

#3. Translate Technical Documents Faster

You can automatically program the CAT tool to suggest certain technical terms during the translation project. Hence, by avoiding guesswork for an appropriate vocabulary, you save time. 

#4. Save Time on Non-Productive Tasks

When you use a CAT tool, you can focus on simply translating since the tool’s interface shows a clean text markup. However, on the back end, it saves all the HTML tags, CSS codes, URLs, etc., that a website might contain.

You do not need to manually add HTML codes, CSS, hyperlinks, etc., to the content later when the task is complete.  

#5. Affordable and Cost-effective

Many popular CAT software is available for a dirt-cheap subscription plan. In return, you save a lot by not commissioning unnecessary manual translation services. 

#6. Abundant in the Market

You can easily subscribe to a CAT tool, as many are in the market. Also, these tools only require a browser, so you do not need to upgrade workstations frequently. 

#7. Bring Consistency to Translation

A CAT software builds the initial translation workflow your team can follow so that the output content is high quality and according to client guidelines for translation.

It also automatically suggests standard technical terms to save time from guesswork. 

#8. Run Collaborative Projects

All the top-notch CAT applications are on the cloud. The tools offer a shareable link for the translation work you have taken up. Just share the link with an external or internal collaborator for teamwork.  

#9. Save on Translation Costs

Save on Translation Costs by using CAT tools

The translation memory of a CAT tool stores translated content from all past projects. Whenever you feed new content to be translated, the tool scans the existing memory to look for similar phrases, sentences, paragraphs, etc.

It shows all the matching content in a percentage figure. If you see a 20% match, then you can save 20% on the per-word billable value.  

How Do CAT Tools Work?

The main purpose of CAT software is to offer extensive support to linguists and translators during the translation process.

First off, such software will offer a translation editor interface that enables you to input content to be translated. Some CAT applications also offer machine translation services. Hence, when you enter the content, you get a roughly translated output. 

Now, you can go through the raw content and make some changes according to sentence nuances to make the translated content free-flowing and easily understandable.

Secondly, most CAT apps come with a translation memory module. It creates a database of all the previous translation projects. Hence, when you enter new content, the tool scans the existing database for matching sentences and paragraphs. 

So, you can recycle old translations instead of translating content from scratch. Then you can translate the leftover content to complete the project.

Thirdly, computer-assisted translation tools also come with a terminology management module. You can upload a glossary of technical words, keywords, brand-approved vocabulary, etc., and the tool will show you where to use the words when translating the content. 

Not to mention, some software comes with dynamic machine learning. Such tools learn from human translators and apply the translation to another part of the document containing similar words, phrases, and sentences.    

Features Every Robust CAT Tool Should Have

Here are the functionalities you must look for in CAT software for business use: 

  • A translational memory to store translations from past projects in searchable segments.
  • A translation glossary or term base that suggests technical words, keyphrases, etc., from a pre-programmed dictionary.
  • It should allow you to share your translation workspace with collaborators via online link sharing.
  • Since such tools are mostly cloud-based software, there should be stringent data security protocols like content encryption, authentication, and so on.
  • The CAT tool provider must clearly state that it will not monetize your project’s translated or non-translated content.
  • There should be a functional proofreading module that will automatically highlight mistakes.
  • Machine learning capabilities to learn translation patterns from human translators and apply that in other parts of the content.
  • A good CAT software must include an automatic content formatting module so that the translated content looks highly similar to the input content.   

Now, it is time to explore some popular and reliable computer-assisted translation platforms or CAT tools for your next content creation and translation project:
