Software UI Translation for Products That Ship Every Sprint
Software localization services for SaaS and product teams. Buttons, menus, error messages and onboarding flows are translated to fit the screen, keep every variable intact and sound right in each locale.
What Is Software UI Translation?
Software UI translation is the localization of the text inside a product: buttons, labels, menus, tooltips, error messages and onboarding. It differs from document translation because every string must fit its space, keep code variables intact and stay consistent across releases. NexTranslate translates UI strings with professional linguists experienced in UX writing and technical content, and checks every string before delivery.
Why Interface Text Needs Its Own Workflow
Interface text is short, scattered across hundreds of files and read without surrounding context. A two-word label can mean three different things, and a translation that is correct on paper can still truncate a button, break a placeholder or flip the wrong way in a right-to-left layout.
Our software UI translation is built for that reality. Linguists see where each string appears, respect its length, keep variables exactly as written and apply the same terms across every feature, so users get one consistent product rather than a patchwork.
Work runs on AI-assisted drafts, professional linguists and a human QA pass. Subject to project scope, translation, proofreading and QA come for the price of proofreading alone.
Batches can follow your sprint calendar. Our standard target is 24 to 48 hours for suitable string sets, and larger releases get a schedule agreed in the quote.

Every String Your Users Read
User Interface Elements
Buttons, labels, menus, tooltips, navigation elements and overlay text, kept short enough to fit and clear enough to act on.
System Messages and Alerts
Error messages, warnings, confirmations and empty states, written so users know what happened and what to do next.
Onboarding and In-App Content
Walkthroughs, notifications, hints, prompts, feature descriptions and help widgets that guide new users in their own language.
Release Notes and Product Updates
Changelogs and announcements localized with each release, so every market hears about new features at the same time.
Developer and Product Documentation
API documentation, developer guidelines, knowledge base articles and support content, with code samples left untouched.
Cross-Platform UI
Web apps, iOS, Android, hybrid and desktop applications, across multi-device and multi-resolution layouts and responsive components.
What Makes UI Translation Different
Functional text has to work, not just read well. These are the details we handle on every string set.
Dynamic Strings and Placeholders
Variables such as {count}, %s and {{name}} are preserved exactly, and plural and gender forms are built correctly for each locale.
Character Limits and Expansion
German or Finnish can run far longer than English. Linguists work to your limits and flag strings likely to truncate on mobile screens.
Regional Formats
Dates, times, numbers, currencies and units follow local conventions, so the product feels built for the market.
Tone and Formality
Formal or informal address, such as Sie or du in German, is chosen per locale and applied consistently across the product.
Encoding and Text Direction
We test for encoding errors and left-to-right and right-to-left (LTR and RTL) display issues before files reach your build.
Layout and Behavior
Menus, alerts and dynamic strings are localized with their function in mind, so screens keep their structure in every language.
Strings That Translate Without Breaking Your Build
- Variables and placeholders such as {count} and %s are preserved
- Character limits and text expansion are respected
- Plurals, gender and regional formats handled per locale
- Tone and formality matched to each market
- Works with JSON, YAML/YML, XML, Word and PDF files
How UI Strings Move Through Our Workflow
Designed to fit around your release cycle rather than hold it up.

Receive Strings
You send resource files, such as YML, JSON, XML or YAML, or we sync through your localization tool.
- 2
Add Context
Screenshots, character limits and developer notes show the linguist where each string appears and how much space it has.
- 3
Translate
An AI draft with your glossary and memory applied, then a professional linguist edits for meaning, length, tone and formality.
- 4
Check
A second linguist reviews every string, and we run checks on placeholders, encoding, plurals and text direction.
- 5
Deliver and Update
Files return in the same format and structure, ready to merge, and later releases reuse your memory and glossary.
Localization That Fits Your Pipeline
Built for CI/CD and agile teams, our software localization services slot into the way you already ship.
Localization Tools and Repositories
We work alongside your localization tools and repositories for clean handoffs and automated sync. File-based delivery works for any team.
Sprint-Aligned Delivery
New and changed strings are translated in batches that match your release cycle, so localization does not hold up a launch.
Visual Context
Screenshots, staging access or context notes show linguists where each string sits, which prevents layout breakage and guesswork.
Memory and Glossary
Translation memory and a product glossary keep terminology consistent across features and lower the effort on repeated strings.
Quality and Security You Can Depend On
Specialist Linguists
Native-language professionals who work on UX writing, technical strings and software UI translation, matched to your product domain.
LQA on Every String
Every string goes through linguistic quality assurance before delivery, with a project manager experienced in software localization.
Confidential by Default
All linguists sign strict NDAs, and unreleased product content is handled securely.
For Product Teams Shipping Globally
Software UI translation suits teams that release often and cannot afford broken screens in any language.

What is software UI translation?
Software UI translation is the localization of every interface element, such as menus, buttons, labels and error messages, so a product feels native to users in other languages and regions. It also covers in-app help, notifications and onboarding text.
Why does UI translation matter for SaaS products?
Users adopt products they can navigate without effort. A clear, consistent interface in their own language lowers friction, can cut support requests and makes it easier to grow in new markets.
Which string formats do you support?
We support string-based files in common formats. Confirmed formats include YML, JSON, XML and YAML, along with Word and PDF for documentation. Other formats such as ARB, RESX and PO are assessed per project.
Will translations break my UI layout?
Not if limits are known. Our linguists account for text expansion, truncation risk and mobile screens, and we flag any string that is likely to overflow so your team can adjust the layout before release.
Do you preserve placeholders, variables and code-level strings?
Yes. Variables such as {count}, %s and {{name}} are kept exactly as written, and QA checks them before delivery so the build stays functional.
Can you support continuous localization for agile development?
Yes. We deliver in batches that match your sprint cycle and handle ongoing updates for each release. Integration with your CI/CD pipeline or localization tool is confirmed per project.
Can you translate both web and mobile app UI?
Yes. We work on web apps, iOS, Android, hybrid apps, desktop software and enterprise platforms, and return strings in each platform's native format.
Do you offer UX writing or rewriting for clarity?
Yes, on request. If your English UI copy is unclear or inconsistent, we can refine it before translation, which improves every language version that follows.
How do you keep terminology consistent across features?
We use a product glossary, a style guide, translation memory and review cycles set up for your brand. The same term is used for the same feature on every screen and in every release.
Are our product strings kept confidential?
Yes. All linguists are bound by strict NDAs, and unreleased product content is handled securely and confidentially. Additional security requirements are assessed per project.
