Minimal AI writing editor built around prompting from inside the page
Lex is a writing editor with an AI assistant embedded in the document rather than bolted on. You write normally, and when you want help you type a prompt or press a shortcut to generate, rewrite, expand or continue, with the result appearing directly in the draft where you can edit it as ordinary text. It deliberately keeps the interface spare: one page, your words and a prompt box, instead of a dashboard of templates. The company targets professional writers and marketers who already know what they want to say, and it publishes a newsletter on writing with AI. Generation quality tracks whichever model sits behind it.

The assistant lives inside the document. You keep writing in place, select text and ask for a change, and the result lands in the draft where you can edit it normally, rather than in a separate conversation window you then copy from.
Not really. Lex avoids the template-gallery approach many AI writers take, so it suits people who start from their own sentences. If you want structured ad or email templates, a platform such as Rytr or Writesonic fits better.
Free access is limited, so it works for evaluating the editor rather than daily writing with AI. Check the current allowance before relying on it, since limits on plans like this change without much notice.
