Gamma
Gamma generates polished presentations, documents, and one-page websites from a text prompt. It pairs AI-generated copy with automatic layout and design, targeting marketers, founders, and internal teams who need professional-looking decks fast without touching PowerPoint or Figma.
Lex
Lex is a distraction-free writing editor with built-in AI that suggests, rewrites, and continues your prose on demand. It targets bloggers, essayists, and newsletter writers who want a clean canvas with an AI co-pilot that stays out of the way until called upon.
Gamma edges Lex on aggregate — 73 vs 70.
