Paste your Custom GPT's pieces below. Everything runs in your browser. Nothing is uploaded or stored. You get a readiness report and a portable bundle you can drop into a plugin, a Project, or another platform.
What the tool checks
It counts your instructions, lists the knowledge files you need to re-upload, inventories every Action endpoint in your schema, and flags features (browsing, image generation, code analysis, OAuth) that need a decision on the new platform. It does not migrate anything by itself. After the report, follow the checklist, or use the free Chrome extension to export your GPT.
Limits
The checks are simple pattern matches on the text you paste. They catch common issues, not every issue, and they do not test your GPT.
Export your GPT with one click
The free Chrome extension reads the GPT you have open in ChatGPT and downloads a zip with its instructions and, where ChatGPT allows it, its knowledge files.
