Cross-platform AI writing assistant delivering real-time grammar correction, tone alignment, authorship tracking, and team style guides.
Works natively inside Chrome, Safari, Firefox, Edge, Windows, Mac, Google Docs, MS Office, and mobile keyboards to flag grammar mistakes, rewrite tangled sentences, and shift tone toward confident, empathetic, or executive registers.
Deploys contextual AI agents that predict how a target audience will react to a draft, locate credible supporting citations, grade essays against rubric criteria, and generate drafts using up to 2,000 monthly prompts on Pro.
Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.
Enables teams on Pro and Enterprise plans to codify company terminology, ban deprecated jargon, enforce inclusive language, insert shared Snippets, and surface internal company definitions inline.
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.
