ABOUT QUILLBOT

QuillBot and Scribbr are both Learneo properties, which is why Scribbr's own AI detector page points readers at QuillBot's. Prices on the Premium page render client-side and a 40 percent promotional discount was running at the time of checking, so plan names are recorded but figures are not. This record is flagged needs_review until list prices are confirmed against the vendor page.

OVERVIEW

Who is it for?
Students, researchers and writers who rewrite and condense existing text more often than they draft from scratch.
Problem
Rewriting a paragraph to be clearer, shorter or differently toned is slow by hand, and the surrounding jobs - citing, summarising, checking - live in separate tools.
Solution
QuillBot pairs a multi-mode paraphraser with a grammar checker, summariser, citation generator, plagiarism checker and AI detector in one account. A free tier covers limited monthly usage; Premium unlocks all rewriting modes and is billed annually.
What makes it unique
Paraphrasing as the centre of the product rather than a feature bolted onto a grammar checker, plus the ability to pause a subscription instead of cancelling it.

  • Paraphrasing with multiple rewriting modes
  • Grammar and spelling checker
  • Summariser
  • Citation generator
  • Plagiarism checker
  • AI content detector
  • Subscription pause without cancelling
