Collaboration without limits

Effortless collaboration

All translators working on a project can work in the CAT content editor simultaneously without affecting anyone else’s progress. Every collaborator has access to the continuously updated translation assets and the editor can review and edit the translated segments as soon as they are confirmed, resulting in higher quality and consistency in much less time.

No messy cross-editing

The smart segment-locking mechanism prevents project members from modifying another member’s work while it’s in progress. This means that any segment you’re working on will be inaccessible for other translators or editors until you confirm it.


In-context communication

Segment commenting allows project managers to leave comments for specific segments and translators to ask questions in the right context. For general and administrative questions, translators and editors can communicate with the project manager via the main chat on the platform.


A new level of translation productivity

Knowledge-driven global content intelligence

Translation memories allow translators to boost their productivity and consistency by storing translated segments and reusing them for identical and similar source texts. PMs can configure translation memories and share them across different projects.

Expert-enabled AI Agents

Smartcat’s Global Content AI Platform combines expert-driven translation, AI content generation, and adaptive AI agents to streamline global content creation. It transforms manual tasks into intelligent workflows, unlocking strategic efficiency and enterprise-wide innovation at scale.

Consistent enterprise terminology

Easily manage your terminology to ensure it is up-to-date and consistent. Translators can suggest new terms for you to approve. Greenlight or reject translations and terms and add customizable metadata. Smartcat detects terms in all morphological forms!

AI-optimized content at scale

Boost global marketing ROI by pre-filling content with AI-curated suggestions from your top-performing translation memories and glossaries. Customize thresholds to auto-translate and confirm high-confidence matches—accelerating campaign rollout and pipeline growth.

Context

Provide your translators with screenshots or other relevant images by adding them to the segments — this can help you avoid many questions. Additionally, reference fields are available for some file formats, such as string keys for resource files and timecodes for subtitles.

Automated quality assurance

Smartcat’s QA engine helps ensure polished, high-quality translations by catching typos, punctuation issues, capitalization inconsistencies, and more. You can customize checks based on your content type, marking certain issues as critical. Focus on translating while Smartcat’s QA support works in the background to maintain accuracy and consistency.

Placeholders

You won’t have to worry about variables, serial numbers or email addresses being accidentally garbled during translation. By using placeholders you can protect non-translatable text elements from editing to ensure they are transferred safely from the original document to the translation.

Hotkeys

Enjoy even more productivity at your fingertips with keyboard shortcuts. If you worked in other CAT tools before, you won’t have to retrain your fingers, as the combinations for common actions are the same in Smartcat.

From the moment the English content is published to the moment the localized version is published, that happens in half the time than it did before.

Flexibility

It’s web-based

Start translating at home from your Mac and continue at the office on a PC. Wherever you are, whatever OS you use, all you need is a browser to work in Smartcat.

It’s universal

Having tons of different software for different formats is an inconvenience. In Smartcat, you can work with dozens of file types, including those native to other CAT tools, by effortlessly importing them into your account. One tool to parse them all!

It’s easy

Gone are the days when you would have to deploy a server to keep, manage and centralize your translation assets. Your Smartcat account runs in the cloud offering you high availability without any maintenance and instant access to all the resources you store in it without any file size or capacity limitations.

It’s safe

Keeping your backups is important but it doesn’t have to be time-consuming. Smartcat automatically backs up your data to several dedicated servers on a regular basis to ensure that we can recover and restore it as quickly as possible if something bad happens. Which is unlikely as we are proud to maintain an annual uptime of 99.8%.

It’s simple

Smartcat’s powerful features are packed into a friendly and intuitive interface. Forget manuals, start working right out of the box!

It’s reliable

Despite Smartcat’s being web-based, you can continue using it offline if you lose your internet connection. Confirmed segments will be stored in your browser’s local storage until you’re back online.

It’s next door

Smartcat’s servers are located in three different data centers in the US, Ireland and Hong Kong to ensure data safety, improve performance and guarantee availability.

It’s an ecosystem

And if all of that is not enough, you can expand Smartcat’s functionality by integrating it with third-party solutions. Seamlessly connect Smartcat with other applications using our open API to build your custom workflow and manage translation projects in your own special way.
