What is Lex?
Lex is a collaborative document editor with built-in AI tools for drafting, editing, and review. It combines document writing, comments, versions, and sharing features with AI assistance that can rewrite text, generate ideas, and provide feedback inside the document.
The product is aimed at people whose writing goes through an edit process and need a focused workspace for content that must be refined before publishing or sharing. The site highlights use for academic papers, customer-facing copy, important emails, and fiction drafts, and it also supports sharing with collaborators through browser-based links.
