ChatGPT can analyse any existing brand and extract the key elements needed to populate your Brand Guidelines.
How to use it: Simply provide the brand name and URL and paste the prompt below. The AI agent will review the website, look for brand articles and PR online as well as checking reviews and wikipedia to scan not just for how the brand is portrayed by the business, but perceived by customers.
This format gives you a single flexible prompt where you can easily:
Section A - inputs (just brand name and url)
Section B - defines what it analyses & provides topline analysis
Section C - output section; brand guidlines.
Delete Section c9 if you dont want the brand guidelines it creates to be automatically applied to future content generation. If left on then when new content is requested it uses the guidelines as a guide and filter to ensure content is on brand.
