How to Mimic Your Favorite GPT and Make It Run Anywhere

You've found the perfect custom GPT. Maybe it's a brilliant writing editor, a coding assistant that just gets you, or a creative brainstorming partner. The problem? It’s locked inside the OpenAI ecosystem. What if you want that same powerful assistant in Google Gemini, Claude, or another platform?

There's a surprisingly simple method to "mimic" the core functionality of any custom GPT. You don't need to be a developer or a prompt engineering expert. You just need to ask the GPT to explain itself.

This guide will show you how to extract the core instructions from a custom GPT and port them to another AI, giving you a consistent, powerful assistant on any platform you choose.

Why Bother Mimicing a GPT?

Recreating a GPT's instructions elsewhere offers a few key advantages:

• Platform Independence: You're no longer tied to a single service. Use your favorite AI personality wherever you work best.

• Cost-Effectiveness: If your preferred GPT is on a paid plan, you might be able to replicate its core behavior on a free, high-quality model. For example, Google Workspace users don’t need to pay for Gemini Gems.

• Deeper Understanding: This process reveals how custom instructions shape an AI's behavior, making you a more effective prompter.

• Improved Functionality: You can take what you don’t like about the GPT and turn it into something even better.

Claude already natively supports this functionality. Any public Artifact created on Claude can be “Remixed” or “Customized” to generate new and improved functionality.

The 4-Step Guide to Mimicing a GPT

The process boils down to a simple conversation where you ask the GPT to generate its own instructions. This usually works well with simple GPTs that don’t have a ton of steps, branches or that have been trained specially on a lot of documents.

Step 1: Choose Your Target GPT

Select a custom GPT you want to mimic. This works best for GPTs defined by their persona, process, or specific output format. Examples include writing coaches, creative title generators, code reviewers, or role-playing assistants.

Step 2: Prompt the GPT to Explain Itself

Your first goal is to get the GPT to clearly articulate its purpose. Open a new chat with your chosen GPT and use a prompt like this:

This encourages the AI to outline its operational logic, which is the foundation for the next step. Note that not all GPTs are fully open.

Step 3: Ask GPT to draft a Fresh set of Custom Instructions

Now, have the GPT translate its purpose into a set of universal instructions. This is the key to the entire process.

The GPT will now generate a ready-to-use set of instructions that defines its personality, workflow, and guardrails.

Step 4: Transfer and Test

Copy the instructions generated in the previous step. Now, go to your target AI platform (like Google Gemini Gems) and find the custom instructions area.

1. Navigate to your AI's settings. In Gemini, for example, click your profile picture and select "Custom instructions."

2. Paste the instructions you copied into the appropriate field.

3. Start a new chat and test it. Give it the same kind of task you would give the original GPT and see how it performs. You may need to tweak a few phrases for a perfect fit, but the core behavior should be remarkably similar.

A note about Google Gemini Gems. These are just like CustomGPTs. Previously, they were private and could not be shared. But Google just made them shareable.

In recent issues we covered Google's Nano Banana (officially called Gemini 2.5 Flash Image) here and here. And following in the heels of Nano Banana was Seedream 4 (latest, greatest image model from China’s Bytedance).

Now, a new tool called Pippit combines the power of both.

Pippit runs the two image models in tandem, fusing Google's speed and adaptability with Seedream's polished aesthetic. The result is a remarkably versatile and powerful platform for visual creation.

Here’s what it can do:

• Instant Scene Generation: Go from a simple text prompt to a fully-realized world, whether you need a photorealistic moon landing or an anime-style portrait next to your favorite idol.

• One-Click Restyling: Upload a photo and instantly experiment with new hairstyles, makeup, or fashion from around the globe.

• Photo Magic: Sharpen blurry images, colorize old photos, or transform portraits into distinct styles like Pixar or cyberpunk with a single click.

Pippit is a prime example of a growing trend: instead of one model to rule them all, the future may lie in smart combinations that offer the best of both worlds.

To see how they stack up, we ran the exact same prompt through all three platforms. Here are the results.

If you use Claude regularly, some of its most powerful features are turned off by default. I stumbled upon these settings recently and they're game-changers.

Here are three features you should enable to get more out of the tool.

1. Activate AI-Powered Artifacts

If you build mini-tools with Claude's Artifacts feature, you can now give those tools an AI brain of their own. This allows the interactive apps you create to call on Claude's intelligence directly, rather than just being static outputs.

• Why it matters: Instead of just generating code for a tool, you can build a tool that uses AI to analyze data, generate content, or answer questions within its own interface.

• How to enable it: Go to Settings → Features and toggle on AI-Powered Artifacts.

2. Turn On Long-Term Memory

By default, Claude starts fresh with every conversation. Enabling Memory allows it to recall context and details from your previous chats, leading to more personalized and consistent responses over time.

• Why it matters: Claude will remember your preferences, project details, and writing style, so you don't have to repeat yourself in future conversations.

• How to enable it: Go to Settings → Memory and toggle it on.

3. Connect Your Canva Account

Streamline your creative workflow by integrating Canva directly with Claude. You can brainstorm a complex visual idea, have Claude generate a detailed prompt for it, and then ask Claude to create editable designs directly in Canva.

• Why it matters: This closes the gap between idea and execution, turning your text-based concepts into visual designs in a single, fluid process.

• How to enable it: Look for the option to connect Canva in your Claude settings —>Connectors

  

Honestly the Canva AI connector was surprisingly good. Here is my prompts:

I asked Claude to generate a design with Canva. Claude goes about creating this remote MCP connection to Canva, which you will need to Allow.

Claude creates 4 designs that are editable in Canva.

You can just open them directly in Canva and edit the text overlays easily!
