ChatGPT custom instructions that help at work

Custom instructions are a standing brief — not a second brain. Keep them short enough that you still paste real notes into each task.

  1. 01

    Who you are and who you serve

    One sentence each. Example: “I run a small consultancy. I write for busy B2B buyers who hate fluff.”

  2. 02

    How drafts should behave

    GB spelling, short paragraphs, no invented metrics, mark unknowns TBD, prefer checklists over essays.

  3. 03

    What never to do

    No legal/tax advice, no pretending to have browsed when it has not, no filling gaps with plausible fiction.

More context

Custom instructions are a common search on chatgptops.com because most tip lists overfit. Orange Ink — an agency that uses AI across development and operations — keeps instructions short and puts the real system in PDF workflows you can reuse.
