Plain Text Linker is a free Chrome extension developed by Marnes. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. With Plain Text Linker, users can easily open plain text URLs by simply double-clicking on them.

This extension provides a convenient way to access URLs embedded in plain text. By double-clicking on a piece of plain text, Plain Text Linker analyzes the text and determines if it could be a URL. If it identifies a URL, it automatically opens the link, saving users the hassle of manually copying and pasting URLs into their browser.

It's important to note that the developer has mentioned that this extension will not be maintained further due to lack of interest/utility and the burden it poses. However, it will remain available for download as long as the store allows, and the source code on GitLab will also be available for forking.
