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 writing assistance for journalists — now rebranded as Prism

An editor built around the way newsrooms work, so structure and flow matter as much as speed of drafting.
The engine underneath was built as a large-language-model-based writing assistant rather than a simple summariser or rewriter.
The project has evolved into Prism, a platform for defining and executing complex AI processes, with journalism features maintained at Newsrun.ai.
