Smartling vs Contentoo: Which should you choose?

Expanding into global markets can often be a daunting proposition for an enterprise. One of the bigger concerns lies in the tension between the need to scale content rapidly whilst ensuring every piece is authentic, well-translated, and localised.

 Both Smartling and Contentoo are designed to solve this problem. They help brands connect with a worldwide audience without the logistical nightmare of tracking all the bits and pieces and the workflows. 

Each system has its strengths. But they approach the problem differently. Smartly operates ‘LanguageAI,’ an AI platform that automates translation and workflows. In contrast, Contentoo is a more curated approach.

AI speeds up the process, but there is always a human who understands the subtleties of translation and localisation for different markets. 

Which one is better for your business? Let’s take a look at each to help you decide. 

What is Smartling?

Smartling, in brief, is a translation management system that automates the localisation of global content. AI does all the heavy lifting, from auto-detecting new content to translating and publishing the work wherever you like. 

Smartling offers an easy-to-use platform for delivering translations quickly and at reasonable rates, and it integrates with many existing CMS, CRM, and marketing tools, including HubSpot. 

According to Smartling, the platform can automatically select the right translation models and apply context, with continuous improvement as you scale.

What is Contentoo?

Contentoo is a managed content workflow solution that combines AI, human expertise, and operational systems so marketing teams can scale content without adding operational overhead or compromising quality.

The Contentoo platform uses AI to improve efficiency while keeping humans in the loop – integrating AI and human expertise – ensuring your content is always consistent, on-brand, and of the highest quality.

Smartling alternatives: What to consider

If you’re still undecided or want to look further afield, we’ve got a few ideas you might chew over first.

Consider your goals. Do you prefer speed or quality? Some businesses want to be part of the process or ensure the work aligns with your brand's voice and needs. And they want to ensure localisation that specifically fits every market. Others just want to get it done.

Consider your challenges. We’ve rarely seen a marketing team that feels they have enough time or resources to get everything done. So they’ll look for a platform that automates processes and rolls everything out across new markets. 

We suggest you look for features such as collaborative editing, real-time feedback, app integrations, and easy file sharing, which can make all the difference in ensuring quality while streamlining content creation and distribution. 

How much does quality matter? ‍Of course, nobody wants to put out subpar content. But serious thought leadership tailored to every market may be more important than efficiency. If it’s the former, consider a platform with access to a range of pre-vetted subject-matter experts. 

Consider what you want from the platform. Does it absolutely have to work with your existing tech stack? Or are you comfortable with an easy-to-use external platform? Either way, it’s best to check if the platform offers content management processes and version control. 

It’s also a good idea to look for end-to-end freelancer or expert talent management, so you don’t have to worry about tracking contracts and invoices through separate systems. Find something that lets you do it all in one place.

Smartling vs Contentoo: Which should you choose?

It’s really the difference between bulk AI translation and localised thought leadership.

If you’re looking to quickly get your content AI-translated and updated, go for Smartling.

For marketing teams who want localisation embedded into end-to-end content workflows – without having to deal with multiple tools and workflows – Contentoo will be a better fit. 

Contentoo also provides the quality and peace of mind that you get with a human in the loop, so you don’t have to worry about AI hallucinations or localising blunders.
