Where each stands
Grammarly
Pros
- Works nearly everywhere you type, which is a genuinely different experience from a standalone editor
- Real-time suggestions catch errors before you hit send, not after
- Free tier covers the core grammar and spelling checking most people actually need
Cons
- Full generative rewriting and advanced tone features are gated behind paid tiers
- Suggestions on stylistic choices can be overzealous, flagging intentional phrasing as an error
- Business and Enterprise pricing is a real step up from the individual plan
Sudowrite
Pros
- Purpose-built for long-form fiction, with tools general writing assistants don't offer
- Story Bible keeps generated content consistent with established plot and character details
- Credit rollover on higher tiers rewards writers with an inconsistent output pace
Cons
- No permanent free tier, only a limited trial before billing starts
- Credit-based system means heavy drafting can burn through a monthly allowance fast
- Narrow focus on fiction makes it a poor fit for non-creative writing tasks
