How to Use Lex in 2026: Step-by-Step Guide
AI writing tool for long-form content built inside a clean document editor, with AI assistance for drafting, editing, and overcoming writer's block on essays and articles.
Lex is an AI-powered document editor built for writers who work on long-form content — essays, articles, blog posts, scripts, and reports. It positions itself as the intersection of a word processor and an AI writing partner: the writing experience feels like a clean, distraction-free document, but AI assistance is always a keystroke away.
Core workflow: You write in Lex's editor like a normal document. When you're stuck or want suggestions, pressing a keyboard shortcut (typically Ctrl+Enter or a dedicated button) sends your cursor position and recent context to the AI, which generates a continuation. You can accept, reject, or regenerate suggestions without leaving the document flow.
Feedback and revision: Lex can read your full draft and offer feedback on argument structure, clarity, transitions, and tone. The feedback is holistic — it engages with what you're trying to say — rather than surface-level grammar correction.
Brainstorm mode: From a prompt or title, Lex can generate an outline, key arguments, or alternative angles before you start writing. This is useful for tackling new topics or exploring different approaches to a piece.
Collaboration: Lex supports real-time collaborative editing, similar to Google Docs. Multiple writers can work on the same document simultaneously with live cursor visibility.
Export and integrations: Documents export to Google Docs, Markdown, or plain text. Lex integrates with Medium for direct publishing. The editor supports standard formatting: headers, bold, italic, lists, and blockquotes.
Audience: Lex has been adopted particularly among journalists, newsletter writers, academics, and essayists who want AI assistance without leaving a writing-focused environment. It's less suited for structured content workflows (content marketing with templates, SEO-optimized posts) where tools like Jasper or Writesonic offer more scaffolding.
Pricing: Lex offers a free tier with limited AI uses per day. Lex Premium ($8/month or $72/year) unlocks unlimited AI, collaboration, and advanced features. There is also an annual team plan for organizations.

Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Lex what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
