Lex review
A capable collaborative writing workspace with limited AI access on its free plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Lex combines a collaborative word processor with AI support for writers working on notes, emails, academic papers, customer-facing copy, fiction, and other drafts. Its writing toolkit covers AI feedback, brainstorming, rewriting, line-level checks, custom saved prompts, and a prompt builder. Writers can also create style guides for drafting and editing in their own voice, maintain persistent knowledge bases for context, and manage documents with version history and named versions.
The free plan provides document sharing and collaboration, making Lex accessible for teams or individuals who need a shared writing workspace. AI access is limited on that plan. Lex Pro adds access to premium AI models, early access to selected features, and priority email support. That structure makes the free tier suitable for collaborative drafting with selective AI assistance, while Pro is aimed at writers who need broader model access and a higher level of support.
Lex fits writers who want drafting, editing, collaboration, and reusable writing context in one workspace. Its web, iOS, and API availability supports browser-based writing, mobile access, and document creation workflows. Read-only publishing links add a simple way to share finished material, while the listed Kit integration provides an external connection. The product is more focused on writing workflows than on a broad integration ecosystem, so it suits writers prioritizing AI-assisted composition and document collaboration over extensive app connectivity. Choose Lex for shared drafting and voice-aware editing; consider another tool if broad integrations or unrestricted free AI access is central to the workflow.
