X Markdown Exporter is a Chrome add-on designed to facilitate the copying and archiving of X (formerly Twitter) posts, threads, and notes into a structured Markdown format. This tool is particularly useful for users looking to feed content into AI tools like OpenClaw or ChatGPT, minimizing issues related to webpage scraping or formatting inconsistencies. It allows for seamless integration into local knowledge workflows, making it easier to manage and analyze online content.

Key features include one-click Markdown text copying, file downloads, and support for exporting content from both tweet detail pages and note pages. The extension ensures that the original order of text and images is preserved, while also converting external link previews into Markdown links. Users can choose from various export modes, and all processing is completed locally in the browser, ensuring privacy and security by not uploading content to third-party servers.
