The Best Machine Translation Software You Can Try in 2025

When it comes to text translations, businesses now have a credible alternative to engaging a human translator: using machine translation software.

Machine translation software (known as MT software) is an artificial intelligence-based tool that provides automated translations of text between different languages, such as from English to Spanish or vice versa. Although machine translation software didn’t have the highest translation accuracy when it was first developed, technological improvements over the decades allowed such software to do a pretty accurate job.

As a result, this category of software is often integrated into computer-assisted translation (CAT) tools and used by businesses involved in international projects. For example, international businesses intending to localize their web pages may use machine translation software to translate large amounts of text at scale.

However, MT software isn’t used only for translating websites. It can also translate documents required to maintain successful international business relationships.

The financial upside of investing in translation is clear: According to a survey by Common Sense Advisory (now known as CSA Research), Fortune 500 businesses that spent more on translation were 1.5 times more likely to report an increase in total revenue than their counterparts that didn’t.

Read on as we explore the top machine translation software options, compare their strengths and limitations, and show you how to effectively implement website translation for your business.

Why Website Translation Software Matters

There’s a reason why some of the largest corporations on the market make translation a priority and use translation software to do it: it’s profitable.

For starters, native English speakers make up less than 5% of the global population, despite 52% of websites being written in English, indicating that many websites are leaving profitable markets untapped.

That’s because, while the Internet’s content caters more to English speakers, consumers are 73% more likely to purchase something on a website in their native language.

Big businesses are aware of this. Microsoft, for example, has translated its products into over 90 languages, Toshiba into over 30, and Apple into 40.

In the long run, translating your website will boost sales rates and enhance your marketing efforts, such as SEO.

More than half of Google searches are non-English, so how can you outrank international competitors if you’re not creating content in your target audience’s native language? 

The answer: You can’t. That’s where machine translation software comes in. Machine translation can help you to localize your site and enhance multilingual SEO to expand your market reach.

That's because your non-English speaking visitors are more likely to engage with your website when reading content in their mother tongue. Over 56% of consumers said that getting information in their own language is more important than price.

Most modern browsers include the functionality to integrate with common online translators (using advanced machine translation systems), native speakers will feel much more at ease knowing that a website has been originally served to them in their own language, rather than having to translate text from a foreign language manually using their own translation apps.

Take respond.io as an example. The customer conversation management platform uses Weglot to translate its website into fifteen new languages. Since using the solution, the site has increased traffic and impressions growth 2x. If respond.io got these results, there’s no reason why you can’t enjoy similar results too!

The Evolution of Machine Translation into 2025 (And Beyond)

Let’s be honest: When machine translation was first launched, it wasn’t the best.

The first experiments in machine translation began in the 1950s, with early systems relying on rule-based machine translation (RBMT). By the 1970s, RBMT technology had matured, using a set of grammatical rules and bilingual dictionaries to translate text. However, these systems often produced literal or rigid translations, as they struggled to handle linguistic nuances.

As a result, machine translation got a bad reputation almost immediately. Unimpressed by the poor accuracy of machine-translated text, people began to dismiss machine translation as being inferior to “proper” (read: human) translators, and thus preferred website translation services for their content, for example.

From Rules-Based Machine Translation to Statistical Machine Translation

Fortunately for machine translation providers, machine translation began shedding its negative image as the technology evolved. After RBMT, came statistical machine translation (SMT), which translates text by analyzing existing human translations, known as bilingual text corpora. Then, it uses prediction algorithms to determine the best way to translate text in any given situation.

SMT was a major improvement over RBMT, but its accuracy was still lacking at times. However, development didn’t stop there. Today, the latest and greatest machine translation technology available is neural machine translation (NMT), which uses complex deep learning models to translate text.

Enter Neural Machine Translation

Neural Machine Translation (NMT) is capable of generating high-quality translations with the help of sophisticated language translation algorithms. These translations are not only more accurate but also sound more natural than the translations produced by RMBT and SMT technologies.

These days, the effectiveness of NMT has quelled most of the opposition towards machine translation. Even objections such as “But machine translation can’t pick up or translate text in images and PowerPoint slides!” have largely been silenced — advanced machine translation tools can do just that.

Generative AI: The Future of Machine Translation Software?

The rise of large language models (LLMs) and generative AI in 2022-2023 has opened up new possibilities for machine translation. Unlike traditional NMT systems that are trained specifically for translation between language pairs, generative AI models are trained on vast amounts of multilingual data and can understand context across languages more holistically.

These AI models show promise in handling nuanced translations, including idioms, cultural references, and context-dependent meanings that have traditionally been challenging for machine translation. For example, they can often maintain consistency in tone and style across longer pieces of text, and some can even adapt translations for specific industries or audiences.

However, it's important to note that generative AI isn't replacing NMT entirely. Instead, many translation providers are exploring hybrid approaches that combine the strengths of both technologies. This combination could potentially offer the reliability and efficiency of traditional NMT with the contextual understanding and adaptability of generative AI.

Should You Use Machine Translation Software for Your Business?

Machine translation is now widely used in the market, a lifesaver for international businesses that need access to consistently accurate translations in the most efficient way possible. Even professional translators adopt automated translation technology to streamline and accelerate the translation process!

But why? Here are some benefits of machine translation software, which your business can also enjoy:

• Easy to use: Machine translation software is so simple to operate that you won’t need a tech background to use it like a pro. Fire up the software, copy/paste your source text, set your target language, and get the translated text in real-time.
• Faster results: Machine translation software can translate text in seconds while human translation can take hours or even days, depending on the text volume.
• Reliable: While the accuracy of machine translation software translations may vary, they are generally reliable. The software is typically vetted by expert translators and native speakers before release.
• Great value for money: It costs a lot less to invest in machine translation software than to hire a professional translator – especially if you’re looking to translate uncommon language pairs, or need translations within a short turnaround time.
• Seamless operation: Some machine translation software can integrate with other platforms for smooth translation workflows. No tedious copy/pasting of text between software and platform needed!
