How to Use Lex in 2026: Step-by-Step Guide
AI writing editor built for long-form content — write with GPT-4 autocomplete, generate text on demand, and maintain focus with a distraction-free interface.
Lex is a writing tool that integrates AI assistance into a clean, distraction-free editor. It is designed for people who write seriously — essays, articles, newsletters, and books — and want AI help that feels native to the writing process.
The Writing Experience
The core interface is minimal: a clean editor with no sidebars and no clutter. AI assistance is available when you want it, invisible when you do not.
AI Autocomplete: As you write, Lex offers ghost text suggestions — like Gmail Smart Compose but for long-form prose. Press Tab to accept a suggestion, keep typing to ignore it. Suggestions are contextual to your document.
Generation on Demand: Hit a keyboard shortcut and Lex generates a continuation based on what you have written. It reads the full document before generating to maintain your voice and direction.
Rewrite: Select any passage and ask Lex to rewrite it — more concisely, more formally, more vividly, or in a different voice. Shows original and suggestion side-by-side.
Document Organization
Documents are synced in the cloud with version history tracking every save. Share documents publicly with a Lex link for feedback without exporting.
Collaborative Writing
Real-time collaboration lets multiple writers work in the same document simultaneously, with AI features available to all collaborators.
Who Uses Lex
- Newsletter writers maintaining weekly publishing cadences
- Essayists and bloggers who value the writing process
- Journalists working on longer pieces
- Professionals who write frequent long documents
What Lex Is Not
Lex is intentionally minimal — not a full content marketing platform. No SEO tools, no keyword research, no publishing integrations. A writing tool first.
Pricing
Free tier includes limited AI generations. Lex Pro (~$18/month) adds unlimited generations, longer documents, and collaboration.
What You'll Need

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.
