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 pre-submission reviewer and writing coauthor for researchers
Upload a draft as PDF or Word and get a full reviewer-style report covering argument, methodology, evidence, structure and clarity, with findings graded by severity.
Relevant articles are matched from an index of 200M+ peer-reviewed papers, and the platform explicitly avoids fabricating citations that do not exist.
Get a ranked shortlist of venues matched to your manuscript, with fit, impact factor and selectivity detail to help you choose where to submit.
Agents search sources, read your PDFs and edit your document, with automatic version history, live co-author collaboration and LaTeX-to-PDF compilation.
