Make erasure poetry from websites.
Click the extension and choose whether you want to blackout or whiteout text – then just click and drag to start making poems! The best way to save your poems is to choose "File > Save Page As…" and select "Web page, Single File". The resulting .mhtml file will preserve the whole webpage with your redactions. You can then open it again in Chrome. For more info on erasure: https://en.wikipedia.org/wiki/Erasure_(artform)
