Lex is a minimalist collaborative document editor with integrated AI tools designed for marketers, sales professionals, and writers seeking focused, efficient writing. It offers real-time collaboration, AI-powered editing, brainstorming, rewriting, version control, and customizable prompts to enhance content creation from quick notes to complex documents. Accessible via mobile web and featuring a developer API, Lex supports teamwork and productivity with features like AI feedback, chat, publishing links, and writing statistics, making it ideal for professionals aiming to streamline their writing process.

Lex blends minimalist design with genuinely useful AI features, making it a strong pick for those who want more than just another document editor. The integrated grammar and style checks plus a document-specific chatbot streamline everything from drafting sales emails to refining marketing copy. Version control and focus mode are thoughtful touches that keep writing organized and distraction-free.

However, the free plan’s limited AI access and restrictions on collaboration features can be frustrating, especially for small teams or power users. For businesses looking to centralize content creation and revision—like managing multiple versions of campaign messaging—Lex shines, provided they invest in the Pro tier. Ultimately, Lex offers a polished experience but expect to pay for its best features.
