At work I need to use Teams. It supports a few Markdown features, but the editing experience for long message isn't smooth. So, I often write in nvim, preview it in the browser and then copy paste to Teams. This tool help me get rid of the review and copy step.Build with Rust + Claude Code. Tested on Windows and Mac, should works on Ubuntu as well.
Caveats: it's still up to the pasted app to handle the HTML clipboard content.
