Lex

Lex is a clean, distraction-free document editor with built-in AI feedback, editing, and brainstorming aimed at writers who want assistance without surrendering their voice. It emphasizes critique and clarity over bulk generation, draws on several underlying models, and offers a free tier plus a paid Pro plan. It is a strong fit for essays and newsletters and a poor fit for high-volume SEO content.

Lex started life inside the media company Every and spun out as a standalone product led by co-founder Nathan Baschez. Its pitch is deliberately narrow: a minimalist, Google-Docs-style editor where AI is present but optional. You can ask Lex to critique a draft, suggest a continuation, brainstorm angles, or check clarity, and it draws on a range of underlying models rather than a single one. The experience is built around writing feedback more than raw generation. Features like AI reviewers that read your draft against a rubric, inline copy-editing, and a chat sidebar are meant to sharpen work you have already written rather than replace it. This makes Lex a comfortable fit for essayists, newsletter authors, and nonfiction writers who care about keeping their own voice. Lex offers a free tier with a monthly cap on AI actions plus a paid Pro plan that unlocks premium models and monthly AI credits. Pricing has shifted over time, so the figures below should be confirmed on the vendor's site. It is not a heavy-duty SEO or long-form content machine, and teams needing high-volume publishing pipelines will find it intentionally lightweight.
