Mark Copy AI vs Lex — features, pricing, and which to choose for your SEO workflow in 2026.
Quick Verdict
Mark Copy AI and Lex represent two distinctly different approaches to AI writing. Mark Copy AI is built specifically for marketing teams who need to generate SEO-optimized content at scale while maintaining brand voice consistency. Lex, on the other hand, is a minimalist writing editor designed for authors, bloggers, and content creators who want AI assistance without the complexity of marketing-focused features.
The choice between these tools ultimately comes down to whether you need a comprehensive content marketing platform or a clean, distraction-free writing environment. Mark Copy AI excels at generating marketing copy, social media posts, and SEO content with brand guidelines baked in, while Lex focuses purely on the writing experience with inline AI suggestions that feel more like a smart writing assistant than a content generator.
Feature Comparison
Mark Copy AI comes loaded with marketing-specific features including SEO optimization tools, brand voice training, content calendar integration, and templates for everything from Facebook ads to blog posts. The platform can analyze your existing content to learn your brand voice, then apply that consistency across all generated content. It also includes keyword research integration and content scoring based on SEO best practices. Lex takes the opposite approach with its intentionally minimal feature set. The editor focuses on inline AI suggestions that appear as you write, helping with everything from sentence completion to paragraph restructuring. There's no template library, no SEO tools, and no brand voice training—just a clean interface that gets out of your way. Lex does offer collaborative features and version history, making it better suited for long-form projects that require multiple drafts and iterations. The content quality differs significantly between the two. Mark Copy AI produces marketing copy that's optimized for conversions and search engines but can sometimes feel formulaic. Lex's AI suggestions tend to feel more natural and contextual, helping writers maintain their own voice while improving flow and clarity.
Pricing Comparison
Lex wins decisively on pricing with its completely free tier that includes unlimited AI suggestions and basic collaboration features. Their paid plans start at reasonable rates for additional features like advanced collaboration and priority support. Mark Copy AI starts at $39/month, positioning it as a business tool rather than an individual writing assistant. While they offer a free tier, it's limited in scope and clearly designed to encourage upgrades. The pricing reflects Mark Copy AI's positioning as a comprehensive marketing platform rather than a simple writing tool. For teams that need the full suite of marketing features, the price point makes sense, but individual writers will find much better value elsewhere.
Best For
Mark Copy AI is the clear choice for marketing teams, agencies, and businesses that need to produce consistent branded content at scale. If you're managing multiple social media accounts, running ad campaigns, or need SEO-optimized blog content that maintains brand voice across different writers, Mark Copy AI's specialized features justify the higher price point. Lex is perfect for individual writers, authors, bloggers, and anyone who values a clean writing experience over marketing bells and whistles. If you're working on long-form content like articles, books, or research papers, Lex's distraction-free interface and contextual AI suggestions will enhance your writing process without overwhelming you with unnecessary features.
The Verdict
For most content creators, Lex offers better value and a superior writing experience. Its free tier eliminates financial barriers while delivering genuinely helpful AI assistance that improves your writing without taking over the creative process. Mark Copy AI only makes sense if you specifically need marketing automation features and have the budget to support a premium business tool. Unless you're running marketing campaigns or managing brand content across multiple channels, Lex's simplicity and affordability make it the smarter choice.
