Lex
AI-powered collaborative document editor that understands your voice and helps you write faster
Overview
Lex is a web-based collaborative document editor that integrates AI to suggest style improvements, expansions, and proofreading as you write. Unlike classic article-generation tools, Lex focuses on improving your own writing in real time, progressively learning your voice and tone preferences. The free plan offers 30 AI checks per month and basic collaborative editing access. The Pro plan costs $14.99/month on annual billing or $24.99/month on monthly billing and unlocks unlimited checks, access to premium models (GPT-4, Claude 3.5 Sonnet, Claude 3 Opus), and advanced team collaboration.
Lex offers no French-language interface and remains exclusively in English. The tool has no documented public API, limiting external integrations. No specific information on GDPR compliance or data-hosting location is accessible on the public site. Lex targets writers, journalists, and content creators seeking lightweight collaboration with AI suggestions rather than a full content-generation suite. The key advantage is preserving your voice authenticity: AI assists without dominating, making it an appealing alternative to tools that produce entirely generated content.
Our verdict
Best for writers, content creators, and consultants who already write well and seek discreet AI help with editing and collaboration without excess artificiality. Not for you if you need complete article generation or a broad tool suite: Lex focuses on improving what you write, not creating from scratch.
