ScriptGrain vs Grammarly
ScriptGrain generates new writing in your measured voice. Grammarly, which most people already have open, corrects the writing in front of it and nudges tone; it does not write as you.
The actual difference
Grammarly corrects the writing in front of it and can nudge tone toward a guide. ScriptGrain measures 45 attributes of how you write and then generates new work constrained to that profile. One improves a draft you wrote; the other writes the draft.
Grammarly's paid tier includes one style guide and one brand tone; unlimited requires Enterprise. ScriptGrain's Operator plan is £29/mo for three voice profiles. Note Grammarly's pricing is region-dependent: we saw euros, and you may see a different currency.

Where Grammarly is stronger
The default writing assistant for most people, and the only tool here that learns your voice passively.
- Passive learning: nothing to upload, the profile builds itself as you type
- A genuinely useful free tier, which most of this category no longer offers
- Grammar and clarity checking that ScriptGrain does not attempt at all
- Works everywhere you already write, via the browser and desktop apps
If what you want is grammar and clarity checking across every app you use, Grammarly does that well and ScriptGrain does not do it at all. They solve different problems and plenty of people should have both.
