You

I need to write a monthly update for my manager. Before you draft anything, ask me five questions about what happened this month.

AI

Good idea. Answer in rough notes and I'll tidy them up.

  1. What did you finish this month?
  2. What is behind schedule, and why?
  3. What decision do you need from your manager?

Every guide ends with a prompt to copy

Read the guide, then paste the prompt into Claude or ChatGPT. It explains what you want to do and asks your AI to walk you through it, using your own work.

  • Starts a conversation, not a one off answer
  • Works in the AI tool you already use
  • Every prompt also lives in the prompt library
Prompt · Set up a project so AI remembers your work
I want to set up a project in this AI tool so you remember the background to my work and I stop repeating myself in every chat.

Interview me one question at a time about my role, the work I do most often, who I usually write for and how I like answers presented. Then draft the project instructions for me to paste in, keeping them under 200 words, and suggest which documents would be worth adding as files.
