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)
Writesonic
+ Daily AI visibility tracking across ChatGPT, Gemini & Google AI Overviews
+ Action Center translates data into a specific, ranked fix queue
+ Citation gap tool shows which external pages AI engines prefer over yours
+ AI Article Writer 6 included on every plan
+ 7-day free trial, no credit card required
− Full Action Center requires Enterprise (Growth capped at 5 actions/mo)
− Claude, Perplexity & Grok tracking locked to Enterprise
− Large price jump from Starter ($79) to Basic ($199)
− Not a replacement for Ahrefs/Semrush on backlink depth
