Lex
AI writing editor for essays and long-form articles that helps you get unstuck with inline suggestions - without rewriting your voice.
Lex is an AI-powered writing editor designed for thoughtful long-form writing - essays, articles, newsletters, and reports - where maintaining an authentic voice matters more than speed. Unlike tools that fully generate content, Lex focuses on helping writers get unstuck: you write until you pause, and Lex offers contextually relevant continuations and alternative framings that you accept, modify, or discard. Built by Nathan Baschez and Dan Shipper of the Every newsletter company, Lex launched in 2022 and grew to over 100,000 registered writers. The platform uses leading LLMs behind a collaborative editor interface that feels closer to a focused writing app than a chatbot. As of 2025, Lex added AI commands, document chat, and direct publishing to newsletter platforms.
Key Features
- Inline AI autocomplete that continues your writing in your voice without replacing the full document
- AI commands - select any text and apply instructions like "make this more concise" or "rewrite as a list"
- Document chat - ask questions about your draft to get structural suggestions or fact-check ideas
- Distraction-free editor with a clean interface focused purely on the writing experience
- Version history to compare and restore prior drafts at any point in the writing process
- Direct publish to connected newsletter or blog platforms without exporting
- Comment and share mode for getting feedback from editors before publication
Use Cases
- Essayists and newsletter writers who want AI assistance without surrendering their personal writing style
- Journalists drafting long-form articles who need to push past writer's block without starting from scratch
- Researchers writing reports who use Lex to translate dense notes into readable narrative prose
- Business writers crafting memos, proposals, and strategy documents that need to sound human and specific
Pros
- Preserves writing voice better than any competing AI tool - assistance is additive rather than replacement-oriented
- Clean editor removes the visual noise of feature-heavy tools like Notion or Google Docs
- Built by the Every team means it is continuously refined by daily working writers, not just product managers
Cons
- Not suitable for high-volume content production - Lex is optimized for depth and quality over speed
- Free plan word limits restrict use for writers who produce content frequently
- No native citation or reference management for academic or research-intensive writing workflows
