Overview

Lex is a minimalist AI writing editor designed for long-form content creation. It combines a clean, Google Docs-style interface with inline AI assistance that helps writers push through blocks, generate ideas, and refine drafts without switching tools.

The AI features are triggered contextually — users can ask Lex to continue writing, rephrase a paragraph, or brainstorm directions for a piece. The Pro plan includes access to GPT-4o and Claude 3.5 Sonnet, giving writers access to top-tier language models directly in their editor.

Lex is best suited for writers, essayists, bloggers, and newsletter creators who want AI assistance without the overhead of a full content marketing platform. The collaborative features support team editing with shared folders.
