Academic proofreading, plagiarism checking and AI-powered writing tools in one place
A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
An undetectable AI humanizer with a built-in multi-detector checker
Paste AI-written text and uPass rewrites it with vocabulary and sentence structures that read like a person wrote it, rather than simple synonym swapping.
Check a passage against several popular detectors in a single run instead of submitting it to each service separately, and see where your text stands.
Select Basic, Advanced or Aggressive depending on how much restructuring the text needs while keeping the meaning intact.
The rewriter generates varied phrasing designed to keep output free of matches flagged by plagiarism checkers as well as AI detectors.
Delivers broader real-time grammar and tone correction across web apps, but lacks Scribbr's deep academic focus and citation formatting.
