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.

An AI tutor that turns your PDFs, videos and lectures into notes, quizzes and conversations
Drop in PDFs, slide decks, YouTube links, web pages, files and recorded lectures. Individual file uploads can reach 2,000 pages / 300 MB on Pro and 5,000 pages / 500 MB on Max.
Ask questions about your own documents and get answers with references back to the original passages, so you can verify claims instead of trusting a generic model response.
Turn any upload into personalized practice tests with answer breakdowns and progress tracking, so revision targets your actual weak points.
Convert study material into podcast-style audio, AI-generated video explanations and narrated read-aloud text — useful for passive review or hands-free learning.
