Choosing ai translation & localization
Is machine translation good enough to publish?+
For many languages and plain content it is close, but legal, marketing, and safety text still needs a fluent reviewer. Use glossaries and review workflows to keep terminology consistent.
What is the difference between translation and localization?+
Translation converts text; localization adapts formats, cultural references, screenshots, and layout. Localization platforms manage the whole process, not just the words.
