Proofreading, review and revision

Semantix offers proofreading, review and revision by local language professionals who specialise in your industry.


Proofreading ensures that spelling and punctuation is correct, without losing the meaning of your communication. Our language professionals ensure the text has natural flow and is idiomatically correct.


A review looks at the content of the text to ensure that it’s correct and appropriate for the agreed purpose. This could include a review of text that has been written in a language by a non-native writer.


A translation is compared with the original text to ensure that it is appropriate for the agreed purpose, that cultural references and terminology are used correctly and that it matches any reference material.
