ScriptGrain vs HyperWrite
ScriptGrain keeps a persistent, inspectable profile: 45 named attributes measured across everything you have published. HyperWrite matches whatever examples you paste, then forgets them.
The actual difference
HyperWrite matches the style of the examples you paste. ScriptGrain measures 45 named attributes across everything you have published and keeps that profile as an artefact you can inspect, edit and re-check: the measurement is the product, not a step inside it.
HyperWrite's entry plan is $19.99/mo for three personas. ScriptGrain's Operator plan is £29/mo for three profiles, and Writer is £12/mo for one.

Where HyperWrite is stronger
Pitches personas directly at the same problem: "Make the AI write like you, not like a robot."
- Three personas on the entry plan, where most rivals give one
- A broad set of one-click writing tools beyond voice matching
- Browser extension that works across the web
Three personas at the entry tier is genuinely better value than most of this category, and if you want a general-purpose writing toolkit rather than a voice engine, HyperWrite covers more ground.
