## What it does

This GPT works like a content planner you talk to. It opens with questions about your business, your audience and your goals, then turns your answers into a set of post ideas. Each idea is written for one platform, not copied across all of them, and each comes with an image prompt you can paste into an image generator.

The value is in the pairing. A caption without a visual is half a post, and most planning tools stop at the caption. Here you get the words and the art direction in one pass.

## When to use it

Use it when a month is about to start and you have nothing scheduled. Use it when you are launching something and need a week of posts that build on each other. Use it when your feed has gone stale and you want formats you have not tried.

Skip it for real-time replies or comment moderation. This is a planning tool, not a community manager.

## How to brief it

1. Describe the business in a few lines. What you sell, who buys it, and the one thing you want to be known for.
2. Name the platforms you actually maintain. Dropping one you neglect is fine.
3. Give a goal for the period. Followers, signups, event attendance, replies. Pick one primary.
4. Share the constraints. Tone, words to avoid, offers that cannot be published yet, brand colours for the images.
5. Ask for a fixed number of ideas per platform so the output stays usable.
6. Request the image prompt in a consistent style, such as clean product photography on a neutral background, so the visuals look like a set.

## What a good session looks like

A good session starts with you answering questions rather than pasting a brief. The GPT should push for specifics: who the buyer is, what they worry about, what proof you have. Vague input produces vague posts.

Expect a spread of formats. A carousel outline for Instagram, a short text post for LinkedIn that opens with a claim, a thread hook for X, a question post for Facebook. Each idea should carry a line explaining why it fits that platform.

Check the image prompts before you generate anything. A strong one names the subject, the framing, the light and the mood. For example: a ceramic mug on a pale oak desk, morning light from the left, shallow depth of field, muted colours. Weak ones say only the topic.

If the first batch feels generic, go back with one correction rather than starting over. Tell it which ideas landed and which did not, and ask for more in the direction that worked. Two rounds usually gets you a month of posts you can schedule without rewriting them.

Keep the best outputs in a running document. Over time that becomes your own bank of formats and prompts, tuned to what your audience responds to.
