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.
Search publicly exposed cloud storage buckets and see what data they leak.
Query exposed buckets by name, keyword or provider and see which ones return publicly readable results.
Narrow results by file extension so you can assess whether sensitive document, database or media files are publicly reachable.
Surfaces the storage endpoints behind each match, making it easier to verify exposure and route a disclosure to the right owner.
Built for security research workflows — quickly triage public exposure without touching the underlying data irresponsibly.
