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.
Free open-source dictation that runs speech-to-text on your own machine
Press a configurable hotkey and your words are typed into whichever app has focus — chat clients, editors, browsers and terminals alike.
Run on-device models such as Whisper or NVIDIA Parakeet for full privacy, or switch to cloud transcription with your own provider API keys.
Spoken instructions like "clean this up" or "draft an email" let the model restructure and polish the raw transcript before it lands.
Names, jargon and technical terms are auto-learned from your corrections so recurring vocabulary stops being misheard.
