Paperpal is an AI writing tool for academic research, strongest at language: grammar and tone suggestions, paraphrasing, plagiarism checks and pre-submission checks, inside Word, Google Docs and more. Papero is a writing workspace for the whole paper: an outline with a prompt for every section, sentence suggestions, citations from real scholarly records and six review checks.
