What is Lex?
Lex is a minimal, distraction-free writing editor with AI built in — think Google Docs meets a smart AI collaborator, without the clutter. You write in a clean interface and invoke AI with ++ to get suggestions for continuing your thought, rephrasing a sentence, or generating new ideas. The AI is conversational, not template-driven, making it feel more like writing with a partner than filling in a form. Free tier is available; Pro is $12/month and unlocks unlimited AI usage and feedback features.
What is Sudowrite?
Sudowrite is purpose-built for fiction writers — not marketers, not developers, not business users. Features like Story Engine, Shrink Ray (condenses scenes without losing meaning), Expand (elaborates sparse passages), and Describe (generates sensory descriptions) are designed around the actual creative process. The Story Bible organizes characters, settings, and plot elements so the AI maintains consistency across a long manuscript. Plans start at $19/month for Hobby (up to 30,000 AI words/month), $29/month for Professional (90k words), $59/month for Max (300k words).
