Does this tool change my ChatGPT login? No. This tool runs alongside your account. It does not touch your login credentials or your private account data.
What happens if the tool stops working? Check the releases page for updates. Developers release new versions if the main ChatGPT interface receives updates. Running the newer installer restores functionality.
Does this cost extra money? This tool is free. However, if you choose a paid AI provider, that provider may charge you based on your usage.
Can I uninstall the tool? Yes. Use the "Add or remove programs" feature in your Windows settings to remove the patcher. Your Codex program returns to its original, factory state.
Does the app track my information? No. This tool operates on your local machine. It sends data only to the AI provider you select for your chat request.
If the menu does not appear, ensure you have the latest version of the main Codex application. Older versions of the app may not support the patching process. Restart your computer after the installation to ensure all changes take effect. If you see an error message, confirm that you have an active network connection, as the app needs to talk to the AI provider servers.
