Composer writes LinkedIn and X posts in your voice, from a rough brief or an idea, and schedules them.

**Where to find it:** sidebar → **Content → Composer**.

## Three ways to start

| Mode | Use it when |
|------|-------------|
| **Start with a brief** | You know what you want to say: a story, a lesson, an opinion. Ghost shapes it into a post. |
| **Idea Studio** | You know the pillar but not the angle. Ghost gives you five different directions. |
| **Write manually** | You want to write it yourself, add media and schedule it. |

## Post details

| Setting | Options |
|---------|---------|
| **Content pillar** | One of your [pillars](https://www.growwithghost.io/docs/getting-started/persona#4-content-pillars) (required) |
| **Post structure** | **Recommend** (Ghost picks the best fit and avoids your recent patterns), **Story** (moment → turn → lesson), **Point of view** (belief → evidence → conclusion), **Observation** (noticing → meaning → invitation), **Breakdown** (example → analysis → next step) |
| **Voice inspiration** | My style (default), Top creator, Lead generation, AI expert, B2B creator, Founder/CEO |
| **Target length** | Concise (~80 words), Short (~140), Standard (~250, recommended), Long (~400) |
| **Post brief** | What it's about. Click the mic to dictate. |
| **Match My Voice** | Apply your voice sliders from Persona hub |
| **AI model** | Claude Sonnet 5.5 (default), Claude Opus 5.5, Claude Haiku 5.5, Grok 4.6, GPT-5.6, Gemini 3.8 Flash or Gemini 3.1 Pro. Your choice is remembered. |

If you have X switched on in **Settings → Account → Content Platforms**, choose LinkedIn or X. For X, pick a single tweet or a 3–5 tweet thread, and turn on **X Premium** for 4,000 characters instead of 280.

If you have more than one LinkedIn profile connected, choose who you're **Posting as**.

## Idea Studio

Pick a pillar and Ghost suggests **five** different directions, each with a structure, a short brief and an outline (opening, beats, ending). Ideas draw on high-performing posts from the creators Ghost studies. For any idea you can see the outline, get **more like this** or **try another angle**, or select it to draft.

## Refining a draft

Every generation is kept as a version, so you can go back. To improve a draft:

- Use the quick buttons: **Rewrite opening**, **Change structure**, **Make specific**, **Tighten**, **Rewrite ending**.
- Or type an instruction, like "make it more casual" or "add a number from our case study". Ghost edits just that part and keeps the rest.
- **Clean up** removes formatting left over from pasting or AI.
- Ghost suggests 3–5 hashtags, which you can add or remove.
- Type **@** to tag a person or company.

## Performance analysis

Ghost scores a draft out of 100 on **Hook**, **Proof**, **Authenticity**, **Value** and **Actionability**, plus an overall score. It runs when you click **Save to Approved**, and the score is shown in your Content library. Aim for 70+ across the board.

## Media

- **LinkedIn:** JPG, PNG, GIF, WebP, or a PDF (shown as a swipeable carousel, with a title you set). Up to 10MB.
- **X:** images only.

Video and polls aren't supported.

## Save or schedule

| Button | What it does |
|--------|--------------|
| **Schedule Post** | Pick a date and time (09:00 by default) and who to post as. Ghost publishes it automatically. |
| **Save to Approved** | Ready to go, not scheduled yet |
| **Save Draft** | Keep working on it later |
| **Discard Post** | Throw it away |

There's no "publish now" button. To post straight away, schedule it a few minutes ahead, or **Copy** the text. See [Content library and scheduling](https://www.growwithghost.io/docs/content/content-library).

## Limits

- **LinkedIn posts:** up to **2,600 characters**. LinkedIn's own limit is 3,000, and the margin stops posts being rejected.
- **AI posts per month:** your plan includes a monthly allowance (125 on the standard plan), reset on the 1st. Writing manually doesn't count.

## Tips

- Put a real story, number or opinion in the brief. The more specific the input, the less generic the post.
- Use **Recommend** for structure until you know what works for you.
- Post 3–5 times a week, across all your pillars.
