Copilot Chat Personal instructions: your style in 5 steps

Tired of repeating how you like your answers?

Save them once; Copilot Chat on GitHub uses them every time.

You need: Any Copilot plan, including the no‑cost tier, and Copilot Chat on github.com. Plan source: GitHub Docs: plans for GitHub Copilot

Steps

  1. Open Copilot Chat on GitHub.
  2. Click your profile picture (bottom left), then “Personal instructions”.
  3. Type your instructions in any format, such as Always provide examples in TypeScript.
  4. Optional: pick a template and replace placeholders like {format}.
  5. Click “Save”. Your instructions stay active until you change or remove them.

Heads-up

  • Personal instructions work only in Copilot Chat on github.com.
  • They take priority over repository and organization instructions, though Copilot still gets all of them, so avoid rules that conflict.
