Switch from ChatGPT to Claude

Switching from ChatGPT to Claude is simple: you create an account on Claude and start using it; you don't have to uninstall anything or leave ChatGPT the same day. The only thing that takes some work is bringing over what you already had set up: your custom instructions, the reference texts you use often and the information about you or your business you'd been giving it.

What's confusing is thinking everything moves over by itself. Conversations from one service don't magically appear in the other, so the practical thing is to save separately what you actually reuse (instructions, templates, your company's details) and give it to Claude again at the start. It's also worth allowing a few weeks of living with both: at first you miss shortcuts and habits, and it's normal to use both for a while until you see which one handles each task better.

I made that switch and today I work mainly with Claude, although I still use OpenAI for some things. In "Why I switched from ChatGPT to Claude" I explain what pushed me to switch, what I miss and which tasks I still give OpenAI, in case it helps you decide whether it's worth taking the step. My down-to-earth advice: don't do it in a rush or in the middle of an urgent job.
