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.
Fraud and abuse detection that recognizes visitors, bots and risky accounts under any masking
Recognizes returning visitors across cleared cookies, incognito sessions and changed IP addresses, and links multiple accounts that trace back to the same person or device.
Flags multi-accounting, account sharing, account takeover and impossible travel out of the box, with a confidence value per event and no fraud model training required.
Names the risk signals behind each result: VPN, proxy, Tor, private relay, datacenter, anti-detect browser, incognito mode, JavaScript disabled, OS and timezone mismatch, browser automation and AI bots.
Scores every visit 0–100 and classifies it as trusted, suspicious or dangerous, then aggregates a single traffic-quality score with breakdowns by channel, referrer and UTM campaign.
