# Social caption generator trained on your own writing

Captions are short enough that voice is almost all there is. Strip out your rhythm and your habits and there is nothing left to tell it apart from anyone else's.

## Why it matters here

Short-form is where a tone description fails hardest: there aren't enough words for 'friendly, professional, approachable' to mean anything. A measured profile still works at forty words because it describes how you build a sentence, not what mood you are in.

## How ScriptGrain does it

1. Give it captions and posts you have already published.
2. The profile captures your quirks at the level short copy actually lives on: punctuation habits, filler phrases, whether you use exclamation marks at all.
3. Captions are drafted to that profile, so brevity does not flatten the voice.

Captions default to around 120 words and skip the outline step, so you go straight from brief to draft.
