AI Document Editor That Gives Real Writing Feedback
Lex (lex.page) is an AI-powered word processor built by the Every team that combines a clean, distraction-free writing environment with deeply integrated AI editing tools. Unlike tools that require you to copy text to a separate AI interface, Lex's AI lives inside the editor itself — accessible through keyboard shortcuts and inline commands. Backed by $2.75 million in seed funding from True Ventures, Lex is designed for writers, journalists, academics, and professionals who want an AI co-editor that provides honest, actionable feedback rather than generic praise.
How Lex Works
You open a document in Lex and begin writing in its clean interface. Type +++ anywhere to trigger AI continuation, generating the next sentences based on your context. Press Command+K (or Ctrl+K) to open the command bar for generating content, creating lists, or changing headings. The Ask Lex sidebar opens a built-in AI assistant with pre-loaded prompts for getting feedback, sharpening introductions, and identifying weak arguments. AI Checks run grammar, brevity, cliché, readability, passive voice, and confidence analysis — each flagged in pink with one-click application or explanation.

Who Should Use Lex?
Lex is built for writers, journalists, academics, and professionals who want a clean, focused writing environment with AI feedback built directly into the editor. It is particularly valuable for writers who want AI that provides honest critical feedback — Lex is notably less sycophantic than using ChatGPT or Claude directly to critique writing. The annual plan at $14.99/month is competitive for daily writers who value the distraction-free environment alongside AI editing capabilities.
