About Lex
Lex is a document editor first and an AI tool second. You write, then ask for feedback on the draft, brainstorm, or rewrite a passage. Comments, version history and live collaboration work the way writers expect. It claims over 300,000 writers and names Google, Microsoft, Harvard and Stanford among its users. Pricing is the gap: the site names a Pro tier offering bigger models and early features but does not publish what it costs, so budget after a trial.
