QuillBot is a set of writing tools: a paraphraser with several modes, a grammar checker, a plagiarism checker, an AI detector, a summarizer and a citation generator, on the web and in Word, Chrome and your phone. Papero is a workspace for writing the paper itself, with an outline, sentence suggestions, citations from real scholarly records and six review checks.

QuillBot and Papero do different jobs. QuillBot is a toolkit for rewording and checking text you have already written. Papero helps you write the paper in the first place, with an outline, sentence suggestions, citations from real records and a review before you submit.
Yes, if you want help writing the paper and not only rewording it. Papero gives you an outline, sentence suggestions, rewrites, OpenAlex paper search, lookup by DOI, PMID, arXiv ID or ISBN, and six review checks in one editor.
Papero Plus is $12 a month or $96 a year, VAT included. QuillBot's Premium page showed us €8,33 to €9,95 per month, billed annually, on the same day in October 2026; its price varies with where you are and the offer it shows.
Papero rewrites the text you select: paraphrase, simplify, make it more academic, shorten, expand, fix grammar, or your own instruction. QuillBot offers more paraphrasing modes and languages.
QuillBot has a citation generator with 1,000+ styles. Papero finds papers for the sentence you are writing and builds the reference list in APA 7, MLA 9, Chicago author-date, Harvard or IEEE.
Papero never uses your documents to train AI models. QuillBot's help centre says it trains its AI on user data, including feature usage and quality signals.
Yes. Write and cite in Papero, export the document to Word, and reword or check a passage in another tool before you submit.
