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.
Read and chat with PDFs right beside ChatGPT, Claude and DeepSeek.
PDFs render directly in the sidebar next to the chat, so your document and the AI conversation are visible at the same time.
Summarize a whole document, translate it, or have passages explained in simpler terms using the AI you are already signed into.
Built-in buttons cover the common actions, and you can edit their prompts to make the AI respond in the format and tone you need.
Ask about charts, scans or regions that cannot be selected by taking a screenshot question instead.
