GoPDF

GoPDF is an online PDF toolkit with AI features. In the browser it lets users edit PDFs by adding text, images, shapes and freehand annotations, fill forms and add digital signatures, request signatures from others and track the document, compress files, convert between formats such as Word and JPG, and merge, split or remove pages. A mobile app is also offered for converting PDFs. The AI side includes chat with a PDF and a Q&A generator that scans an uploaded PDF and produces quiz style questions and answers, pointing to where in the document each answer appears. The quiz tool is suited to training materials, manuals and study guides, and works best on text based PDFs, since scanned documents may need OCR first. Uploads to the quiz tool are limited to files under 40 MB and five pages. The vendor markets the tools as free, with no installation and no signup needed to start. A subscription plans page exists, but its rates are not published in readable form on the site.
