Why the settings, not a message?
ChatGPT can’t add tools from inside a chat, so you add Welder once in its settings and sign in. There’s no key to copy. If you pasted a Welder setup prompt, ChatGPT walks you through these same steps.
- 1
In ChatGPT on the web, open Settings → Security and login and turn on Developer mode.
- 2
Open Apps (Plugins), click + and create an app. Name it Welder and paste the link.
