It is widely used by students, writers and professionals.

Paperpal is an AI writing assistant built for researchers, academics, and students. It proofreads and rewrites academic prose in real time, suggests citations, checks references, and reads PDFs — all from inside Microsoft Word, Google Docs, Overleaf, the Chrome extension, or the web editor.

Jenni is an AI research and academic writing workspace that helps students, researchers, and academics read, write, and cite in one place. Bring in PDFs or import a Zotero or Mendeley library, and Jenni's autocomplete suggests sentences grounded in your own sources, with every suggestion linked to the exact page and paragraph. A built-in writer, AI chat, citation engine covering 10,000+ styles, and a Reviews tool for catching weak or unverified claims make it a full environment for producing cited papers.
