About ChatGPT Prefix/Postfix Helper

This extension allows you to automatically add a custom prefix and or postfix to your ChatGPT prompts. You can create multiple templates, set one as default, and switch between them directly in the ChatGPT interface using a convenient dropdown and a "Send + Fix" button. All settings are stored locally in your browser. The extension does not track, transmit, or store any data. Ideal for reusing prompt structures, adding context, or streamlining your workflow with ChatGPT. Source-Code: https://github.com/finman-at/gptfix
