Lex vs Sudowrite

Lex is a collaborative writing assistant that pairs a minimal document editor with in-line AI feedback, rewriting, and brainstorming. You draft in a clean word processor, invoke Ask Lex inside the document, and get suggestions on the text you already wrote. The product is built for long-form work such as essays, fiction, newsletters, and anything that goes through real revision. Lex says more than 300,000 authors use the editor on its homepage.

Most AI writing apps start from a blank prompt and optimize for first drafts. Lex assumes you already have words on the page and puts the model beside you as an editor: line-level Checks, custom saved prompts, Style Guides trained on your samples, and Knowledge Bases that carry project context across sessions. That layout fits revision-heavy workflows where you switch between human collaborators and model feedback in one document, which is a narrower bet than template-driven copy generators.

Newsletter writers, essayists, novelists, and editorial teams show up repeatedly in Lex testimonials and its pricing FAQ. Students, academics, and nonprofits can request discounted Pro pricing by emailing [email protected]. Teams can collaborate on documents for free and add Lex Teams for shared folder workflows when collaboration volume grows.

Lex Pro unlocks premium models and $30 of monthly AI credits for $14.99 per month on an annual plan ($179.88 billed yearly on lex.page/pricing). Free accounts still include collaborative editing with capped AI usage. Sharing live edit links, publishing read-only pages, and editing from mobile web all work without installing a desktop app.
