Short answerInstructions copy over as text, but lines that mention ChatGPT features (browsing, image generation, file names, Actions) may not make sense elsewhere. Find and rewrite them, then test tone and format against saved answers.
Lines to look for
| If your instructions say | Do this |
|---|---|
| "Use web browsing" | Confirm the new platform has search; otherwise remove or rephrase |
| "Generate an image with DALL-E" | Remove or point to another tool |
| "Use the uploaded files" or file names | Update names; say to answer from the provided reference material |
| "Call the X action" | Rename to the new tool or remove if not rebuilt |
| Output format rules | Keep, then test; models vary |
The free checker flags several of these automatically. After editing, run the test set and compare tone.
