Migrate Your GPTs or Gems from ChatGPT to Claude: Practical Guide

Published on April 01, 2026 | Translated from Spanish

Switching AI assistants doesn't mean losing your most valuable customizations. If you're migrating from ChatGPT or Gemini to Claude, you can bring those specialized assistants you created, known as GPTs or Gems, transforming them into Claude Skills. This process ensures the continuity of your workflows and allows you to manage your digital experience without starting from scratch. We explain how to perform this migration in a simple and effective way, focusing on those automations primarily based on instructions.

Steps to convert a GPT or Gem into a Claude Skill 🛠️

The process is straightforward and doesn't require external tools. First, access the GPT configuration in ChatGPT or the Gem in Gemini. From there, copy the three key elements: the name, the description, and, most importantly, the instructions or main prompt. Then, open Claude.ai and go to the Skills section. Click on Create a Skill manually and paste the copied information into the corresponding fields. A crucial consideration is Claude's behavior: it can activate a Skill automatically if it thinks it's relevant to the query. To avoid this and have it act only upon your explicit request, add a clear line in the instructions, such as Activate only when the user explicitly requests to use this skill.

Portability, a user right in the AI era 🧳

This ability to migrate basic configurations between platforms underscores an essential principle: user sovereignty over their own digital customizations. Although the AI ecosystem is advancing rapidly, the ability to carry your simple tools with you fosters experimentation and reduces the fear of change. It's a reminder that, beyond the underlying technology, the value lies in the knowledge that the user embeds in instructions, an asset that should be portable for a truly open and adaptable digital society.
