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-assisted URL threat detection API for developers
Every scan returns a numeric score plus explanatory reasons, so you can act on a link with confidence rather than trusting an opaque verdict.
Short links and redirect chains are unwrapped and followed, revealing hidden final destinations before they reach your users.
Links are classified across phishing, malware, scam, adult, dating, gambling, crypto and spam, supporting nuanced content policies.
Send batches of URLs in a single request and receive per-link risk scores, which suits high-volume pipelines and link shorteners.
