Before and after
I asked Claude the same thing twice: “Write a short email to my customers about the pie order deadline.” The test user is Dana, a made-up bakery owner.
Without the file, Claude guessed. Blanks everywhere:
Hi [First Name], ... the deadline for holiday pie orders is [Day, Date] at [Time]. ... Warmly, [Your Name]
With the file, it wrote like Dana:
Hi neighbors, holiday pies are baking soon, and we’d love to make one for you. Pre-orders close Friday, November 20. ... Thanks for being with us all these years.
The file is one page about you. Claude reads it before every answer, in every chat. It works for any job. I use the same idea for my own notes, in How I gave Claude Code memory without a vector DB.
