What is ScriptGrain?

ScriptGrain measures how a person writes from writing they have already published, as 45 attributes across 8 layers, and writes drafts against that profile. Every draft is scored 0 to 1, the voice match, with per-feature deltas showing which habit moved. The profile is read live over a REST API and an MCP server by advanced models and MCP clients, on every plan including Free. It is not a CMS, a content calendar or an approval tool.

Is ScriptGrain worth the price?

Good value

ScriptGrain's pricing is fair for solo creators but gets expensive for teams.

The Free tier is impressively generous with a full writing analysis and one draft, while the $29 Operator tier offers good value for consultants. The $299 Agency tier is the weakest deal unless you need the unlimited voice profiles and 10 seats, as you can stack multiple Studio accounts cheaper.

ScriptGrain FAQ

How does ScriptGrain help content teams maintain a consistent brand voice across multiple writers?

ScriptGrain measures how a person writes from their published work, capturing 45 attributes across 8 layers to build a unique writing profile. When generating drafts, it writes against that profile and scores the output with a voice match score from 0 to 1, showing per-feature deltas so teams can see which habits aligned or diverged.

How does ScriptGrain differ from Jasper Chat when generating drafts?

ScriptGrain builds a measurable writing profile from a user’s existing published work and writes drafts specifically to match that profile, scoring each draft with a voice match score. Jasper Chat does not offer this kind of quantified voice profiling or per-feature delta feedback.

Which writing tasks does ScriptGrain not cover, such as content planning or approval workflows?

ScriptGrain is not a CMS, a content calendar, or an approval tool. It focuses exclusively on analyzing writing style and generating voice-matched drafts; tasks like scheduling, editorial review, and publishing are outside its scope.

Which teams benefit most from using ScriptGrain for voice-matched writing?

Teams that need to produce drafts consistently matching an established brand or personal voice benefit most, such as marketing teams, content agencies, and individual writers who want to scale their unique style. The profile is accessible via REST API and MCP server, enabling integration into custom workflows.

Does ScriptGrain include a free tier for users to test its voice profiling?

Yes, ScriptGrain offers a free tier that includes access to the writing profile via REST API and MCP server. Paid plans are available for higher usage and additional features.

How does ScriptGrain score the voice match of a draft against a writer's profile?

Each draft receives a voice match score between 0 and 1, indicating how closely it aligns with the writer's measured profile. The system also provides per-feature deltas that show which of the 45 attributes moved away from the profile, offering detailed feedback.

Can developers access ScriptGrain's writing profile through an API or MCP server?

Yes, ScriptGrain exposes the writing profile live over a REST API and an MCP server. This allows advanced models and MCP clients to read the profile on every plan, including the free tier.

How many distinct writing attributes does ScriptGrain analyze to build a voice profile?

ScriptGrain analyzes 45 distinct writing attributes organized across 8 layers. These attributes are derived from writing the user has already published, forming a detailed profile used for drafting.
