About Lex

Lex is a minimalist word processor with AI built into the writing experience. It was created by Nathan Baschez at Every, the media and software company, and later spun out as an independent company. Instead of a chatbot in a sidebar, Lex puts AI inside a calm, distraction-free editor where writers ask for feedback, rewrites, research or continuation directly on their draft.

Writers can highlight a passage and request alternatives, ask the AI to check an argument or suggest titles, and save custom prompts for repeated tasks. Drafts can be shared for comments, and version history tracks changes over time. Lex works with large language models from several providers, and users can choose which model handles their requests. Lex is no longer accepting new customers, and its pricing page shows plan details only to existing users.

Lex suits essayists, newsletter writers, founders writing memos and anyone who wants an editor that helps them think rather than write for them. Formatting options are limited, integrations are few and it is not built for long structured documents or team workflows. Google Docs with Gemini and Notion AI are better for collaborative documents, while iA Writer is a focused editor for writers who do not want AI in the loop.
