Pros & Cons
Lex
+ Cleanest writing interface of any AI tool — pure white canvas, no sidebars
+ AI assist triggered by +++ command, never interrupts flow unprompted
+ Generates multiple alternative phrasings side by side for comparison
+ Multiplayer mode: collaborate with other writers in real time
+ Feedback mode: AI reads your draft and gives structured critique
− No built-in SEO features whatsoever
− Command-based AI requires learning — not for users who want a single button
− Export options are basic (no direct CMS publish)
ProWritingAid
+ 20+ report types: grammar, style, pacing, clichés, sticky sentences
+ Native integrations: Google Docs, MS Word, Scrivener, Chrome
+ Lifetime plan ($399) is the best one-time deal in this category
+ Finds issues Grammarly misses — redundant phrases, passive overuse, vague wording
+ Consistency checker flags character name/timeline errors in long documents
− Interface feels dated compared to Grammarly or Hemingway
− Report system is powerful but requires learning investment
− Not built for SEO — zero keyword or ranking features
