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.
One OpenAI-compatible API gateway for text, image, and video models
Use a single API key and base URL with OpenAI SDKs and compatible tools, or the bare host with Anthropic and Gemini SDKs, to reach text, image, video, and audio models from many providers.
Configure a primary route plus ordered backups for a regular API key so requests can fail over to another eligible route when an upstream provider has trouble.
Every request logs its token usage and cost in the console, with model prices listed beside the official rate for each routing group and billing unit.
Invite admins and members by email, assign unlimited, one-time, or monthly budgets, issue keys prefixed with your company name, top up, and audit every action.
