If you keep pasting the same instructions, you need a saved assistant.

Direct answer

A custom assistant stores your instructions, and sometimes reference files, so you can reuse them for a repeated task, such as drafting customer replies in your tone. Write clear instructions covering role, audience, steps, output format and rules, test with real examples and keep sensitive data out unless your policy allows it.

What to put in the instructions

  1. Role: "You help draft replies to customer emails."
  2. Audience and tone: friendly, concise, plain language.
  3. Steps: read the message, identify the question, draft a reply.
  4. Format: greeting, answer, next step.
  5. Rules: do not promise refunds, ask if information is missing.

Test it

Try five real examples, note failures and refine the instructions.

Keep it safe

  • Do not include confidential information unless allowed.
  • Check sharing settings.
  • Update it when your process changes.
