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.
AI-powered document scoring, evaluation and verification
Upload, analyze, and retrieve documents in a few clicks, with AI reviewing each file against your approved headers and templates instead of relying on manual spot-checks.
Generate consistent numerical scores for every submission so reviewers and stakeholders can compare documents objectively rather than relying on gut feel.
AI writes the reasoning behind each score, giving you an audit trail that explains why a document passed or fell short, which is especially valuable in compliance contexts.
Standard and premium plans condense long documents into digestible summaries, so reviewers can triage a large batch quickly before reading in depth.
