Two ideas for your working day
Keep customer context available
Create a project for each customer with an approved offer sheet, target audience and tone guidelines. Start a separate chat within it for newsletters, LinkedIn and proposals. This lets you reuse the same context and spot inconsistent product descriptions more easily.
OpenAI: projectsReuse approved answers
Save a reviewed positioning statement or a good customer brief as a project source. For the next campaign, explicitly ask for a check against it. Update the source whenever the offer or audience changes so that outdated claims do not carry over unnoticed.
