A translation brief is a project document that states the purpose, target audience, tone, terminology preferences, and practical constraints for a translation or localization assignment, such as file formats, deadlines, and style requirements. It is the reference point that translators, editors, and reviewers use to align decisions when the source text allows more than one acceptable rendering or when client-specific choices must override general convention.
Translation briefs are used at project kickoff for marketing campaigns, product launches, e-learning modules, or regulated content. The brief may be summarized in a style sheet or a client portal entry, and project managers distribute it to all linguists so that tone and terminology stay consistent across the entire language set.
The most common error is starting translation with only the source files and no brief, then guessing at register, audience, or terminology; this creates rework when the client expects a different tone. Another error is writing a brief so vague that it says only "translate into French" without explaining whether the text is for consumers, patients, developers, or regulators.
For creative and consumer content the failure mode is flatness, not inaccuracy — and flatness passes an accuracy check. Terms here also carry technical constraints (reading speed, character budgets) that are part of the brief.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
