A memory is not a machine translator
Translation memory stores previously approved source and target segments. When similar content returns, the system surfaces exact or partial matches so a linguist can reuse or adapt them.
Consistency is the first benefit
Repeated product names, warnings and interface patterns can stay aligned across releases. Cost and speed improvements follow when the stored content is reliable and the new context is compatible.
Maintenance matters
Poor translations, duplicates and outdated terminology reduce the value of a memory. Regular cleaning and clear ownership turn it into a durable client asset rather than a collection of old sentences.
