ScriptGrain

ScriptGrain is an AI writing tool designed to make generated content sound closer to your own writing style. Instead of relying on vague instructions about tone or voice, it starts with samples of your actual writing, measures the patterns that make your style distinctive, and turns those patterns into a reusable voice profile for generating and evaluating new drafts.

The platform focuses on writing style rather than just subject matter. Its analysis covers 45 reference points, including rhythm, vocabulary, structure, punctuation, hedging, paragraph shape, and clause nesting. You get a narrative description of your voice, editable attribute cards, and a voice-match score that shows how closely a new draft aligns with your measured style.

Key Features

Writing Voice Analysis

Build a measurable profile from your existing writing rather than asking AI to imitate your style based on a short prompt.

The analysis looks across 45 reference points, including:

• Rhythm
• Vocabulary
• Structure
• Punctuation
• Hedging
• Paragraph shape
• Clause nesting
• Other stylistic signals

This creates a more detailed picture of how you actually write and provides the foundation for generating content that better matches your style.

Instant Style Preview

Get a quick read on your writing directly in the browser.

The instant preview measures six writing signals without uploading your samples, giving you an immediate sense of the stylistic patterns the platform can identify.

This is useful when you want to explore your writing style before creating a full voice profile.

Full Voice Profile

Create a more comprehensive profile from up to 20 pieces of writing.

You can provide samples through:

• Pasted text
• Files
• Public URLs

The resulting profile turns your writing patterns into a reusable reference for generation and draft evaluation.

Voice-Match Scoring

Measure how closely a new AI-generated draft matches your established writing style.

Instead of simply accepting an AI draft because it sounds broadly appropriate, you can compare it against your measured voice profile and see whether the writing is actually aligned with your style.

This gives writers a way to identify when generated content starts drifting away from their normal voice.

Editable Voice Profile

Review the written description of your voice and correct anything that does not feel accurate.

The profile includes editable attribute cards, allowing you to refine the representation of your writing style rather than treating the initial analysis as fixed.

This creates a feedback loop between measurement, review, and generation.

Free Draft

Try the core workflow without immediately committing to a paid plan.

The free experience includes:

• One complete voice profile
• One generated piece
• No card required

This makes it possible to test whether the measured voice profile actually produces useful style-matched output before choosing a paid tier.

Privacy-Focused Writing Analysis

Your writing samples are not used to train models.

This is particularly relevant for founders, marketers, agencies, and professional writers who may be working with proprietary copy, internal communications, or established brand voices.

Multiple Voices for Teams

ScriptGrain can support teams and agencies that need to work with several distinct writing styles under one account.

Rather than forcing every piece of content into a single shared tone, different voice profiles can represent different people, brands, or writing styles.

Built For Writers & Content Teams

ScriptGrain is designed for people who need AI-assisted writing without losing the characteristics that make their writing recognizable.

• Founders maintaining a consistent personal voice
• Marketers creating repeatable content in an established style
• Operators producing internal and external communications
• Writers using AI while retaining their individual voice
• Agencies managing multiple client or brand voices
• Content teams maintaining distinct writing profiles

Common Use Cases

AI-assisted writing: Generate drafts that are measured against your existing writing style rather than relying only on generic tone instructions.

Founder content: Maintain a recognizable personal writing voice across AI-assisted posts, articles, and other content.

Brand content: Create repeatable output that follows a defined writing style across different pieces and contributors.

Agency workflows: Maintain multiple distinct voice profiles when producing content for different clients.

Draft quality checks: Score generated content against a voice profile to identify where the writing matches your style and where it drifts.

Style documentation: Turn an intuitive sense of how someone writes into a structured, reviewable description of their writing patterns.

Pricing

Pricing is tiered around voice profile count, monthly output, and access to exports, API usage, and team features, allowing the platform to accommodate both individual users and teams working with multiple voices.

Why It Matters

AI-generated writing can be grammatically polished and relevant while still sounding noticeably different from the person or brand it represents. Generic prompts such as "make it sound like me" often leave too much room for interpretation.

ScriptGrain takes a measurement-first approach. It analyzes actual writing, builds a profile from observable stylistic patterns, lets users review and adjust that profile, and then scores generated drafts against it. That makes voice matching something you can measure and evaluate, rather than something you have to judge entirely by intuition.

Make AI Writing Sound More Like You

Build a voice profile from your real writing, review the patterns that define it, and score new drafts against the result. With support for individual writers, multiple voices, and team workflows, ScriptGrain provides a structured way to use AI without flattening the writing style that makes each person or brand distinct.
