Use AI to create a custom style guide that ensures all your financial writing stays consistent and professional.
If you write multiple reports, memos, and updates each month, you've probably noticed your writing style can drift—sometimes you're formal, sometimes casual, sometimes you bury the lead, sometimes you front-load it. Creating a personal style guide with AI helps you lock in your best practices so every piece you write feels polished and consistent. Start by having AI analyze several examples of your strongest financial writing to identify patterns in structure, tone, phrasing, and formatting. Then ask it to document these patterns into a clear, reusable style guide—covering how you open reports, present numbers, write headlines, handle caveats, and close with recommendations. Once you have this guide, you can paste it into ChatGPT alongside any new draft and ask AI to rewrite your work to match your established style. This is especially powerful when you're writing quickly or across different types of documents—it ensures your CFO gets the same clear, confident voice whether you're drafting a variance memo or an investor brief.
