The Verdict
Grammarly Business is built for enterprise and marketing teams, with a focus on grammar-check and tone-detection. Sudowrite targets novelists and screenwriters and leads with story-engine and describe.
Pricing is close: Grammarly Business starts at $15/mo versus $19/mo for Sudowrite — not a deciding factor on its own.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
Feature-wise, Sudowrite offers broader built-in capabilities (7 features vs 6), while Grammarly Business takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Grammarly Business has a slight overall edge — but if purpose-built for creative fiction writing matters most to you, Sudowrite may still be the right call.
