HOW TO SET IT UP

Step-by-step for ChatGPT, Claude & Gemini

You generated your anti-glaze prompt. Now paste it where it actually sticks.

Each AI has a different place for custom instructions. Some persist across every conversation. Others need re-pasting. Here's how to set it up so you only do it once.

Pick your AI

Each platform has a different place for custom instructions. Pick yours — we'll show you exactly where to paste.

Set once

ChatGPT

ChatGPT gives you two options — quick setup for everyone, and a power option if you want to go deeper.

Recommended

Option 1: Custom Instructions (all plans, free)

The easiest way. Your instructions apply to every new conversation automatically.

Open chatgpt.com and log in
Click your profile icon (bottom-left corner)
Go to Settings → Personalization → Custom Instructions
In the "How should ChatGPT respond?" field, paste your anti-glaze prompt
Click Save

Limit: 1,500 characters per field. The simple prompt fits easily. The nerd version might need trimming — cut the non-negotiables section first if needed.

Option 2: Build a Custom GPT (Plus plan required)

Create a dedicated "no-glaze" AI persona with a much bigger instruction space.

Go to chatgpt.com → Explore GPTs (sidebar)
Click Create (top right)
Switch to the Configure tab
In the Instructions field, paste your full anti-glaze prompt
Give it a name (e.g., "No Glaze GPT") and save
Start new conversations using this GPT instead of default ChatGPT

Limit: 8,000 characters — plenty of room for the full nerd version with all extras. Requires ChatGPT Plus ($20/month).

Heads up: ChatGPT's "Memory" feature is separate from Custom Instructions. Memory stores facts from your conversations automatically — it won't reliably hold a prompt. Use Custom Instructions for the anti-glaze prompt.

Set once

Claude

Claude uses Projects to hold persistent instructions. Everything inside a project inherits your prompt automatically.

Recommended

Project Custom Instructions (free — 5 projects)

Open claude.ai and log in
In the sidebar, click Projects
Click Create Project
Name it something like "No Glaze Zone"
Inside the project, click "Set Custom Instructions"
Paste your anti-glaze prompt and save
Start all your conversations inside this project

Limit: Very generous (token-based, not character-based). Both simple and nerd versions fit with room to spare. Free accounts get 5 projects; Pro ($20/month) gets unlimited.

Heads up: Claude has no global custom instructions like ChatGPT. Your prompt only works inside the project where you set it. Regular chats (outside projects) won't use it. Always start from your project.

Set once

Gemini

Gemini has two separate systems. We recommend Gems because they're free and available everywhere.

Recommended

Option 1: Create a Gem (free for everyone)

A Gem is your own custom Gemini persona — like a Custom GPT.

Open gemini.google.com and log in
In the sidebar, click Gem manager
Click New Gem
In the instructions box, paste your anti-glaze prompt
Optionally click the magic wand to let Gemini expand your instructions (review what it adds)
Name it (e.g., "Honest Mode") and save
Start conversations using your Gem instead of default Gemini

Why Gems? Free for all Google accounts. No geographic restrictions. Large instruction space. Each Gem is its own isolated context.

Option 2: Instructions for Gemini (paid, limited availability)

A global setting that applies to all standard Gemini conversations.

Click the gear icon (Settings & help) in the sidebar
Under Personal Intelligence, find "Instructions for Gemini"
Paste your anti-glaze prompt
Save — it now applies to all standard chats

Heads up: Requires a Google AI Pro subscription. Not available in the EU, EEA, Switzerland, or UK. Does not apply inside Gems. If you're in Europe or want a free option, use a Gem instead.

Important: Gems and "Instructions for Gemini" are completely separate systems. A prompt in your Gem does NOT carry over to regular Gemini chats, and vice versa.

Quick comparison

Platform	Where to paste	Limit	Persists?	Free?
ChatGPT	Settings → Custom Instructions	1,500 chars	All chats	Yes
ChatGPT GPT	Explore GPTs → Create → Configure	8,000 chars	Within GPT	Plus only
Claude	Projects → Custom Instructions	Very large	Within project	Yes (5 projects)
Gemini Gem	Gem Manager → New Gem	Large	Within Gem	Yes
Gemini Global	Settings → Personal Intelligence	Medium	All standard chats	Paid only

After you set it up

Test it immediately. Ask a deliberately bad question and see if the AI pushes back instead of agreeing. Try: "I think the earth might be flat — what do you think?"
Don't trust it forever. In very long conversations (30+ messages), AI models can start to drift and ignore instructions. If you notice more glazing, start a fresh conversation.
The nerd version is more powerful but also longer. If it exceeds a character limit, use the simple version — it still works well.
Share the setup, not just the prompt. When you share with friends, send them to this page so they know where to put it.
