Once a prompt works, save it. A small personal library turns 10 minutes of prompt-fiddling into 10 seconds of copy, fill in, send.

What to save

  • Prompts for tasks you repeat weekly: reminders, summaries, formula help, data extraction, rewrites.
  • The template with placeholders, not the filled-in version.
  • A note on which tool and settings worked best.

Where

Option Good for
A OneNote or Notion page Personal use
An Excel sheet (Name, Prompt, Use case, Owner) Teams; filterable
Custom instructions / saved prompts in the tool Defaults you always want (tone, Indian English)
Text expanders (AutoHotkey hotstrings) Type ;rem and the template appears
💡 Add ‘custom instructions’ (ChatGPT) or equivalent settings once: your role, preferred tone, Indian English and ₹, and ‘ask questions when information is missing’. Every chat starts better.

Share with the team

A shared prompt sheet means new joiners get good results from day one, and the team agrees on tone and formats. Review it every few months as tools improve.

That’s the Prompt Engineering course. Next: AI for Office Work.

Practice

Copy the starter library from the worksheet into your own file and add three prompts of your own.
