textcortex vs lex
TextCortex vs Lex — features, pricing, and which to choose for your SEO workflow in 2026.
Quick Verdict
TextCortex and Lex represent two fundamentally different approaches to AI writing. TextCortex positions itself as a comprehensive AI writing assistant with custom personas, brand voice controls, and specific SEO content generation features. Lex takes the opposite approach — a minimalist, distraction-free editor that focuses purely on helping you write long-form content without overwhelming features.
The choice between them comes down to whether you want a feature-rich platform that can handle multiple content types and brand voices, or a clean, focused writing environment that gets out of your way. Both offer free tiers, but they serve very different writing workflows.
Feature Comparison
TextCortex delivers a full suite of AI writing tools including custom AI personas that can write in specific brand voices, multilingual content generation, and dedicated SEO content templates. You can train it on your brand guidelines, create multiple personas for different clients or content types, and generate everything from blog posts to social media content with consistent voice and tone. Lex strips away these complexities in favor of inline AI suggestions that feel more like an intelligent writing partner than a content generator. It excels at helping you develop and expand ideas within long-form pieces, offering contextual suggestions as you write rather than generating entire pieces from scratch. The interface is deliberately minimal — no complex menus or overwhelming options, just you and your words with AI assistance when needed. TextCortex also includes specific SEO features like keyword optimization suggestions and content structure recommendations, while Lex focuses purely on improving your writing quality and flow without SEO-specific functionality.
Pricing Comparison
Both tools start with generous free tiers, but TextCortex's paid plans scale up significantly for teams and agencies that need multiple brand personas and higher usage limits. The free version gives you enough credits to test the persona features and SEO capabilities. Lex maintains a simpler pricing structure focused on individual writers and small teams. Their paid tiers primarily unlock unlimited usage and priority access rather than adding complex features, keeping the focus on the core writing experience.
Best For
TextCortex works best for marketing teams, agencies, and content creators who need to maintain consistent brand voices across multiple clients or content types. If you're producing SEO content at scale, need multilingual capabilities, or want to train AI personas for specific writing styles, TextCortex delivers the features and flexibility you need. Lex is ideal for writers, bloggers, and authors who want AI assistance without feature bloat. If you're working on long-form content like articles, essays, or books and want an AI writing partner that enhances your natural writing process rather than replacing it, Lex provides the perfect minimalist environment.
The Verdict
Choose TextCortex if you need a comprehensive AI writing platform with brand voice control and SEO features. Its persona system and multilingual capabilities make it the clear winner for agencies and marketing teams producing diverse content types. Choose Lex if you prioritize a clean, distraction-free writing experience and work primarily on long-form content where AI suggestions enhance rather than drive your writing process.
