Stop Fighting Default AI: How Custom Instructions Fix ChatGPT & Copilot

Stop Fighting Default AI: How Custom Instructions Fix ChatGPT & Copilot

If you use AI tools like Copilot, ChatGPT, Claude, or Google Gemini regularly, you’ve almost certainly run into the “default response syndrome.”

You ask a straightforward question, and instead of a direct answer, you get:

  • Unnecessary polite greetings and conversational filler.
  • Unsolicited bullet points covering things you never asked for.
  • A flood of irrelevant emojis.
  • US-centric defaults for spelling, currency, and local context.

Instead of wasting time typing long instructions every single session, you can configure Custom Instructions once to set permanent baseline rules for your AI assistant.

Why Custom Instructions Matter

Think of Custom Instructions as background rules for your AI. They tell the tool who you are, how you like information delivered, and what boundaries it must follow before you even hit send.

  • Cut the Scope Creep: Keep answers zeroed in on what you asked for without unrequested sub-tasks or extra steps.
  • Lock in Local Context: Automatically enforce Australian English spelling (colour, organise), AUD currency, and regional relevance.
  • Encourage Real Candour: Instruct the AI to challenge incorrect premises or flaws in your logic rather than just nodding along.

Setup Guide Across Platforms

Setting this up takes less than two minutes on any major platform:

  • Microsoft Copilot: Go to Settings > Preferences > Custom Instructions (or configure within Copilot Studio for enterprise M365 environments).
  • ChatGPT (OpenAI): Click your profile icon, select Custom Instructions, and paste your rules into the response preferences box.
  • Claude (Anthropic): Access Account Settings > Custom Instructions, or define specific system prompts inside individual Projects.
  • Google Gemini: Go to Settings > Personal Intelligence to manage Saved info (your context and preferences), or create a custom Gem to lock in dedicated system instructions for specific workflows.

The Plug-and-Play Template

Copy and paste this instruction block straight into your AI tool’s settings:

Please adhere to the following rules for all responses:

* Tone & Directness: Provide clear, concise, and direct answers. Skip conversational fluff, generic greetings, and meta-announcements (e.g., avoid "Here is what you asked for:").
* Localization: Use Australian English spelling and regional context where applicable. Default to AUD for currency.
* Formatting: Do not use emojis unless explicitly requested. Use bullet points and bold text for easy scanning.
* Direct Scope: Answer strictly what is asked. Do not add unrequested sub-tasks or extra steps unless essential to answer the question.
* Constructive Feedback: If my question contains a flaw, incorrect assumption, or mistake, point it out directly with a brief explanation so I can correct it.
