Lex partnerships and signals
Strategic signalPartnerships
Six partnerships are on record, tiered core and strategic.

- Together.aicoreTogether.ai provides additional LLM models (Llama 3.1, Mistral, etc.) through API. Lex has enabled the setting to exclude customer data from training.

Lex competitors and assessment
Company assessmentDirect peers
- Notion AI: Notion's AI features embedded in its document and wiki editor directly compete with Lex for the same prosumer and team AI-writing market. Both offer AI-assisted drafting, editing, and a minimalist, collaborative writing surface.
- Grammarly: Grammarly is a leading AI writing assistant with line-level editing suggestions closely overlapping Lex's Checks feature, plus a generative AI assistant. It targets the same broad base of individual writers and business users.
- Jasper: Jasper is an AI content generation platform focused on marketing and business content. It overlaps with Lex's marketing-team use case and competes for the same paid B2B content budget.
- Writer: Writer is an enterprise AI writing platform for teams with style guides, brand-voice controls, and APIs. It is the closest functional analog to Lex's Style Guides and Teams tier in a B2B context.
Broad incumbents
- Google Docs (with Gemini): Google Docs is the default free collaborative word processor for hundreds of millions of users and now ships Gemini-powered AI writing features, making it the most significant incumbent threat to Lex's positioning.
- Microsoft 365 Copilot: Microsoft Copilot integrates AI drafting and editing into Word and the rest of Microsoft 365. As a broad incumbent, it can bundle AI writing into enterprise contracts that Lex cannot easily displace.
Emerging players
- Sudowrite: Sudowrite is an AI writing tool specialized for fiction and creative writers. It overlaps with Lex's creative-writing segment and could out-compete Lex in that vertical with deeper genre-specific features.
- Reflect: Reflect is an AI-powered notes and writing app with a minimalist interface and integrated AI assistant. It is comparable to Lex in design philosophy and target prosumer audience.
- Craft Docs: Craft is a document and notes app with built-in AI features and a minimalist design. It competes with Lex in the same clean-design, AI-enhanced writing tool space.
Others
- Scrivener: Scrivener is a long-form writing application used by novelists, screenwriters, and researchers. While not AI-powered, it is a longstanding alternative that Lex positions against for serious creative writing workflows.
