AI document assistant that drafts PRDs, help docs and wikis from a short brief
Describe a problem and a feature, and get a structured first draft you can adapt to your team's PRD template.
Highlight a section and let AI expand, restructure or refine it, with tools like PRD Review that surface gaps before you ship.
Turn a short text prompt into flowcharts, sequence diagrams, Gantt charts and other professional diagrams.
Work in the same document simultaneously, follow edit history, and organize complex documentation in flexible hierarchies.

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.
