The GPT2Markdown extension is a tool that allows users to export their conversations with ChatGPT in a single click, in Markdown format. The extension also has a feature that uses ChatGPT's auto-labelling to name files, and it is open-source. The tool can be used to store the exported conversations in a digital tool like Notion or in a dedicated folder on an external hard drive. The source code for the tool is available on GitHub and the tool requests only bare minimum permissions and does not collect any user data.
