Just the Steps

1. Open settings
2. Search for “address bar” (Privacy, search, and services -> Address bar and search)
3. Select “Manage search engines”
4. Select “Add”
5. Fill in the fields with the following information:
   • Search engine: SearchGPT
   • Shortcut: @ai
   • URL with %s in place of query: https://chatgpt.com/?q=%s&hints=search
6. Click “Save”
