Lex is a minimalist document editor where the AI is a collaborator rather than a generator. Ask it for feedback on a paragraph, have it check for clichés or passive voice, or let it continue when you are stuck.
It supports comments, sharing, and a growing set of custom checks; a free plan covers light use.
