Planning intelligence vs generative AI
Sudowrite is an AI writing assistant focused on generating and expanding prose — scenes, descriptions, dialogue suggestions.
Writing Nexus explicitly does not ghostwrite. Nexa, the AI coach, reviews your structure, flags passive protagonists and missing beats, and asks hard questions — but you write every word.
If you want AI to draft paragraphs, Sudowrite fits. If you want to fix structural problems before 50,000 words of rework, Writing Nexus fits.
