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.

Highlight text in Mail, Slack, Notes, browsers or a code editor, press ⌘⇧K, and Vidix sends the context to your chosen model and inserts the answer in place — no copy/paste or app switching.
Open the palette to search recipes, prompts and agents with arrow keys and Enter, so you can trigger an AI action without leaving the app you are working in.
A Markdown buffer sits between the model and your document so you can iterate with follow-ups like "make it shorter" or "make it legal" before confirming insertion with ⌘⏎.
Chain multiple AI steps into a saved workflow — for example security analysis, performance review, test coverage and documentation steps followed by a summary.
