What is Lex?

Lex is a modern, distraction-free writing platform with sophisticated AI editing tools. Unlike generic AI writing assistants, Lex focuses on enhancing your writing process, not replacing it. These tools are especially powerful with the cutting-edge AI offered by a Lex Pro subscription, which you can test with a free weeklong trial.

Working in Lex

• Writing in the Editor: A clean, focused writing environment. Think Google Docs, but minimalistic. Share “edit” links to collaborate with co-writers, or view-only links to show off your work

• Highlighting Text: Select any portion of your writing to get targeted suggestions with "Edit," or discuss specific sections with "Chat." Lex always reads your entire document before responding, ensuring contextual, relevant feedback

• Collaborating with AI in the Chat: Have a conversation with AI about your writing - either by typing or voice-to-text. Perfect for brainstorming, asking for AI first drafts, getting feedback on in-progress drafts, or chatting with the AI about your ideas (this is especially powerful with “Style Guides” and “Knowledge Bases”—see below)

• Running Checks: Get smart suggestions to improve readability, brevity, grammar, confidence and more across your entire document

AI in Lex

• Premium AI: Access to the latest and most capable AI models (with Lex Pro), including the latest innovations from OpenAI, Anthropic, Google, and more!

Customize Lex

• Style Guides: Train AI to understand and match your voice in minutes

• Knowledge Bases: Give Lex background information and reference materials so it can make smart, informed edits on even the most niche topics (this also just takes minutes!)

• Custom Prompts: Create and save specific instructions for AI to handle recurring writing tasks

• Personas: Choose or create AI personalities that match your preferred feedback style

• Custom Checks: Configure which writing elements Lex should focus on when reviewing your work

What people say about LEX?

"A.I. is known for its "hallucinations" and egregious mistakes -- but not when the engine is tuned like a Maserati. That's what LEX offers the professional writer: a language model with a writer's mind. It's already very good, and the feeling of this A.I. skeptic is that it's only going to get better." - Roger S. H. Schulman, Oscar nominated writer ("Shrek") & Writing Coach (TheWriterCoach.com)

"Lex is my Google Docs replacement… but better. The minimalist interface allows me to focus, and the AI capabilities serve as the real-time editor that helps me iterate more quickly and efficiently on my drafts." - Amanda Natividad, VP Marketing at SparkToro

"From a humble beginner to an accomplished writer, I have tried my fair share of writing tools. But none has come close to the game-changing impact that Lex has had on my writing journey." - Lloyd Osler, Retired CEO and Aspiring Novelist

"While Lex looks like a simple word processor, it’s closer to a writing partner. Its design seamlessly integrates LLMs to amplify your ability without disrupting your flow state. It helps me easily explore ideas from new angles & refine language to communicate them effectively." - Maximillian Piras, Designer at Headliner

"I couldn't be more excited to see all the new changes to this tool! By far the best AI I've encountered!!" -- Amber Goetz, Enterprise Development and SEO

"Lex is the copywriter I've always been seeking.  It checks my work and makes my writing even stronger.  Throughout what makes the writing me remains. Even after providing writing samples, I've found other programs lose that essence." - Diana Stepner, Co-Founder of Product Gold
