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.
Photorealistic digital humans that respond in under 300 milliseconds
Avatars respond in under 300 milliseconds, so conversations feel immediate rather than delayed, and they keep listening, reacting and breathing while waiting for the user.
Rendering happens on-device instead of streaming video from the cloud, which cuts bandwidth to 10–15 KB/s and compute cost to roughly one hundredth of typical cloud video avatars.
Web, iOS and Android SDKs plus simple APIs let developers integrate digital humans into existing apps and agent stacks without a heavy backend.
Appearance, behaviour and voice can be tailored to your brand or AI experience, with natural, controllable motion rather than stiff scripted animation.
