PagePrune: Print Only What You Want
Click anything on a page to delete it, or let Auto-clean strip the ads, menus, and clutter while keeping the article. Print the result, save it as a PDF, or stay and read in peace. Free: cleanup and printing. Pro ($19/year): isolate a selection, saved per-site rules, and image and background removal.
Undelve: AI Writing Checker
Underlines the words and habits that make writing sound like AI while you type. "Delve" and its cousins. Stock phrases, hollow constructions, odd rhythms. Hover an underline and it explains itself, source included. It runs entirely in your browser and it is free. Zero network requests. We run our own writing through it. This page included.
