How software localisation works

Successful software localisation requires more than just translating text: it involves adapting every element of your product to feel natural in a new market, without disrupting its functionality, brand consistency or user experience.

At LanguageLine, we follow a phased approach that ensures both cultural relevance and technical precision from start to finish.

Cultural localisation

We adjust icons, colour schemes, multimedia and layout to reflect cultural expectations and norms, so that your product feels intuitive and familiar in every locale.

Example: Red may signal danger in one market and celebration in another. Our linguists and localisation experts understand these nuances and adjust content accordingly.

Text localisation

We translate and adapt everything from GUI strings to error messages, legal notices and user help content, maintaining clarity, tone and usability in every language.

This includes:

Menus and labels
User documentation and manuals'
Help text and tooltips
Dialogue boxes and alerts
GUI (graphical user interface) content

FAQs

What content types do you localise in software?

UI strings, onboarding flows, error messages, legal disclaimers, menus, in-app help and app store metadata.

Do you provide pre-launch UI testing?

Yes. We help test layouts, character limits and encoding before the localised User Interface (UI) is launched.

AI plus human workflows for faster, smarter software localisation

We can integrate AI agents and machine translation within any of our localisation workflows where it makes sense, and always back it with expert review. That means faster turnaround, reduced cost and zero compromises on quality.

Our AI and MT solutions are customisable and we can design specific programmes to address large volume requirements, as well as simply plugging in to our existing high-quality MT solutions, ready to use from day one.

These hybrid workflows reduce the localisation overhead while maintaining quality, helping product teams meet aggressive timelines and budget constraints without cutting corners
