What is Lex?

Lex is an AI-powered word processor designed for modern creators. It combines collaborative document editing with AI tools that help you write faster and refine your ideas. You can use it for quick notes or complex documents, and it's built to feel polished and focused.

You start by creating a document, just like in any word processor. As you write, you can ask the AI for feedback on your draft, brainstorm ideas, or rewrite any part of your text. You can also generate title ideas with one click, use handy AI shortcuts to find the best word, and create lists of ideas. If you want to try a different way of saying something, the Versions feature lets you experiment without losing your original work.

Lex supports live collaboration—share a link, and anyone can join with one click and see what you're typing. You can publish a read-only link for readers, and use keyboard shortcuts for comments and navigation. The site mentions track changes is coming soon. Lex is loved by over 300,000 writers, including marketing professionals who use it as a Google Docs replacement.

Tips for better results with Lex

  • Use Lex's Versions feature to experiment with alternative phrasings without losing your original text, then compare versions side by side to pick the strongest draft.
  • Ask Lex for AI feedback on a completed paragraph rather than during drafting, so the suggestions target structural issues instead of interrupting your flow.
  • Generate title ideas with Lex's one-click tool after finishing your draft, then refine the top three options by asking the AI to rewrite them for tone or clarity.
  • Leverage Lex's live collaboration by sharing a link with a colleague and using comments to discuss specific sections, keeping the AI feedback for your own revisions.

What to check before you rely on Lex

  • Confirm whether Lex offers a free tier or trial, since the website does not list pricing or plan limits anywhere on the page.

  • Verify that Lex's collaboration works on your preferred devices and browsers, since the site only mentions mobile web support without specifying compatibility.
