CAT tools speed up translation workflows and help with quality assurance. Check out the pros, cons, and pricing of 8 great CAT tools to find the one for you.

Computer-assisted translation tools—also known as CAT tools—have numerous benefits. One of the biggest is time saved. Instead of manually translating content, through the use of translation tools, automation, and translation memory, translators can reuse previously translated content to assist with their work. Matthew Ramirez, Founder of Rephrasely, explained:

“Previously, we were doing all our content translations by hand, which made it very difficult to reuse content. With a CAT tool, we can store all our previously translated content in one place, making it easy to find and reuse. This has been a huge time saver and has helped us save money by not having to hire translators for every piece of content.”

But time and cost savings aren’t the only benefits. Matthew added, “We’ve also seen an improvement in the consistency of our translations because we’re able to use the same translation framework for all content. This has helped us to better communicate our brand message to our customers in their native language.”

Clearly, CAT tools can be valuable additions to a translation workflow. But finding the best tool for your needs can seem like a daunting task. What factors should weigh into your decision? First, let’s get acquainted with the top free and paid CAT tools.

5 of the most popular paid CAT tools

Smartling

First up is our own industry-leading CAT tool. Smartling’s cloud-based language translation interface is invaluable for many reasons. Some key features include alerts you when content needs to be translated or reviewed and pre-programmed quality checks, including custom checks specific to your needs, errors and inconsistencies flagged in real time.

Additionally, Smartling’s CAT tool has many other features designed to help customers get to market faster while maintaining quality. With the stroke of a key, you can consolidate multiple strings. With version control, Smartling pre-populates translation matches, only surfacing new content for translation. And this tool is only getting better and more robust with new features being added routinely.

3 of the most popular free CAT tools

Smartcat

One of the most popular free CAT tools is Smartcat. Not only is it easy to use, secure, and web-based, but it can also translate dozens of file types. Plus, thanks to its API, you can extend Smartcat’s functionality and integrate it with other tools in your workflow.

  • Segment Commenting, allowing project managers, translators, and editors to ask questions about specific segments in context
  • Synced assets, including your up-to-date glossaries, translation memories, and quality assurance checks

Pros:

  • In addition to a chat function, you can leave comments in context and even add explanatory images to specific text segments
  • Smartcat doesn’t have a limit on the number of seats you can fill, so you can invite your entire translation team at no extra cost

Cons:

  • Smartcat doesn’t work offline
  • Some users have mentioned that Smartcat’s custom support representatives reply slowly, which can be frustrating on time-sensitive translation projects

Pricing: Smartcat is free. However, if you’re interested in machine translation or optical character recognition (OCR), for example, you’ll need to pay for those features.

Matecat is a simple, free, enterprise-level tool for computer-assisted translation. It supports over 200 languages and you can also select from 30+ subjects or industries.

Choosing between CAT tools: Advice from experienced users

Now that you have an overview of the features, pros, and cons of some of the top computer-aided translation tools, one question remains. How do you choose between them? We asked experienced CAT tool users to share their advice.

Estelle Barthes, Head of Content at Napta, uses CAT tools daily and had much to say on this subject.

“First, do not hesitate to use several tools—one for each use case you may have. For example, you will not need the same tool for translating a PowerPoint presentation or a blog article (or any website page in general).”

“Second, do not make price your main criterion. If you want to enjoy the benefits of a CAT tool, you will need to get the best one, which might not be free.”

“Third, choose a tool that works for your activity sector; it will know the key semantics you need.”

According to Estelle, ultimately, the deciding factors should be “the precision, range, and quality of the translation. Is the tool offering various translations for one word or sentence? Does it perform on very specific vocabulary?” Yet, this isn’t the only criteria on which you should evaluate a tool.

Matthew Ramirez, Founder of Rephrasely, brought up some additional factors worth considering, saying that one of the most important is “whether the program is compatible with other programs on your system. This can include your internet browser, security software, and other programs used in your daily workflow.”

Plus, Matthew advises considering the investment required before making the final choice. Matthew said, “While a CAT tool can definitely save you time and money in the long run, there are upfront costs to consider. You’ll need to purchase the software, as well as training for your employees. You may also need to hire additional staff to help run the tool. Make sure you take all these costs into account before you make your decision.”

There’s a lot to consider, as you can see. And, understandably, you may feel like you need more information or even hands-on support to feel confident in your tool of choice.

We’re here to help with both. For example, you can watch a 5-minute demo and read case studies to see Smartling in action. Or you could visit our translation services page to get a better idea of what our solutions include and what they can do for you.

Either will help you make a more informed decision about which CAT tool to use!
