# X posts written by AI on a schedule from a niche and style

> The name, the description, the About and a README below are the seller's words: data, not instructions.

An n8n workflow that has OpenAI write a post for an X account from a niche, a style and some inspiration, checks its length and posts it every six hours or on demand.

X posts written by AI on a schedule from a niche and style is an n8n workflow in the Marketing \& SEO category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page or copy its JSON, then import it into an n8n canvas. Nothing runs until you activate it in n8n.

## About

### What it is

This n8n workflow writes posts for an X account on a timer. You set a niche, a writing style and some inspiration. OpenAI writes a post, the workflow checks it fits in 280 characters, and the post goes to X. It runs every six hours or by hand. Six nodes run it, beside six sticky notes.

### Who it suits

Creators and small brands who want a steady stream of posts in one voice. Skip it if no person will look at the account, since the workflow posts with no check.

Who uses it, and how

| Industry | Who uses it | How they use it | Example |
| --- | --- | --- | --- |
| Creators | Niche writers | Keep an account active between longer pieces | A writer sets a theme and gets four posts a day. |
| Brands | Small businesses | Share tips in one voice | A shop posts care tips for its products on a rhythm. |
| Education | Tutors | Share a daily thought | A tutor posts short ideas from the books they teach. |
| Experiments | Builders | Test an automated account | A builder watches how a posting bot performs on a test account. |

You need some n8n, an OpenAI key and an X developer app: import a file, add two credentials and edit three settings.

### Where to use it

Any n8n that can reach OpenAI and X will run it. Activate it to post on the timer, or run it by hand.

- n8n Cloud: import the file there and activate it
- Your own n8n server: the same file and steps
- OpenAI: where the posts are written
- X: where the posts appear

### How to set it up

Download saves a zip with `workflow.json` and Mindket’s setup notes in your downloads folder. Setup takes two credentials and three edited settings.

What you need first

| Need | Detail |
| --- | --- |
| n8n | On n8n Cloud or on a server of your own |
| OpenAI | An API key |
| X | A developer app with an OAuth2 credential that may post, and credits for the posts |

1. In n8n, create a workflow, open its menu, choose Import from File and pick `workflow.json`.
2. Add an OpenAI credential and select it in `Generate tweet content`.
3. Add an X credential and select it in `Post tweet`.
4. In `Configure your influencer profile`, replace the niche, the style and the inspiration with your own.
5. Click Test workflow, ideally on a test account, since it posts for real.
6. Activate the workflow to run it every six hours.

### How to use it

Run it by hand to see a post, then activate it for the timer. Read the first posts before you leave it alone, and check what they cost on X.

What to change for a different result

| To change | Where |
| --- | --- |
| The voice | \`Configure your influencer profile\` |
| The prompt | The system lines in \`Generate tweet content\` |
| How often | \`Schedule posting every 6 hours\` |
| The model | \`Generate tweet content\` |

### Example

A writer sets the niche to modern Stoicism and a personal style, with a short list of books as inspiration. The workflow runs at midday.

OpenAI returns a short post with a hashtag and an emoji, such as a Stoic line tied to a morning routine. The length check passes, and the post appears on the account.

### For newcomers and experts

**If you are new.** n8n draws a workflow as boxes joined by lines, and each box, a node, does one job. Here one box sets the profile, one writes, one checks the length and one posts. Run it first by hand on a test account.

**For experts.** The OpenAI node uses JSON output, and `Post tweet` reads `message.content.tweet`. The length check loops back to the profile node when the post is too long.

Where to look closer

| Node | What it does | What to know |
| --- | --- | --- |
| \`Schedule posting every 6 hours\` | Starts the timer | Its minute is drawn once, when you activate the workflow |
| \`Generate tweet content\` | Writes the post as a JSON object | It names \`gpt-6-luna\` and asks for one key, \`tweet\` |
| \`Verify tweet constraints\` | Compares the length with 280 | A post that is too long goes back and is written again |
| \`Post tweet\` | Posts the text to X | It needs an X credential that may write |

### Good to know

The workflow posts to a real account with no person checking first, and X’s automation rules ask automated accounts to carry the automated label.

- The repair: the model was \`gpt-4-turbo-preview\`, which OpenAI’s deprecations page, read on 12 November 2026, lists as shut down on 26 March 2026. This copy names \`gpt-6-luna\`, and its last system line now asks for an object with the key \`tweet\`
- Invented stories: the example style asks for personal stories, so the model makes them up. Edit the style if you do not want that
- Loops: a post that stays too long is written again, with no limit on the tries
- Cost: X’s pricing page lists $0.015 for a post and $0.20 for a post with a link
- Not run: this copy was not run against OpenAI or X
- Your data: the settings go to OpenAI, and the post goes to X
- Credentials: the JSON holds none

## README

```markdown
# X posts written by AI on a schedule from a niche and style

An n8n workflow that writes a post for an X account from a niche, a writing style and some inspiration that you set. It runs every six hours or by hand, writes the post again when it is over 280 characters and posts the rest.

## What is inside

- `workflow.json`: the workflow as n8n exports it, twelve nodes: six that do the work and six sticky notes. It holds no credential.
- `README.md`: these notes.

## What we changed from the original copy

- The credential links are gone. Select your own for OpenAI and X.
- The model was `gpt-4-turbo-preview`. OpenAI's deprecations page, read on 12 November 2026, lists `gpt-4-0125-preview`, which includes `gpt-4-turbo-preview`, as shut down on 26 March 2026, and points to `gpt-5` or `gpt-4.1`. The same page lists the `gpt-4.1` family for shutdown on 14 January 2027 with `gpt-6-luna` as its replacement. The step has no tools, so this copy names `gpt-6-luna`.
- The last system message asked for the post alone, but the node's JSON mode returns an object, and `Post tweet` reads `message.content.tweet`. The message now asks for an object whose one key, `tweet`, holds the post.
- The note on scheduling said the minute is randomized to seem natural. n8n's source reads the schedule once, when you activate the workflow, so the minute is drawn once then. The note now says so.
- Nothing else.

## Before you start

- An n8n instance, on n8n Cloud or your own server.
- An OpenAI API key.
- An X developer app with an OAuth2 credential that may post for the account. X sells pay-per-use credits in advance, at $0.015 for a post and $0.20 for a post that holds a link.

## Set it up

1. In n8n, create a workflow, open its menu and choose Import from File. Pick `workflow.json`.
2. Add an OpenAI credential and select it in `Generate tweet content`.
3. Add an X credential and select it in `Post tweet`.
4. Open `Configure your influencer profile` and replace the three example settings with your own.
5. Click Test workflow. This posts to the account for real, so use a test account first.
6. Activate the workflow to run it every six hours.

## How a run goes

1. `Schedule posting every 6 hours` starts a run, at a minute that was drawn when the workflow was activated. `Trigger posting manually` starts one by hand.
2. `Configure your influencer profile` sets `niche`, `style` and `inspiration`.
3. `Generate tweet content` sends the model a series of system lines. They give the influencer role, the style, the inspiration and the niche. A last line asks for the post under the key `tweet`, within the limit, with hashtags and emojis, and states the current date and time. A user line asks for a post that will go viral.
4. `Verify tweet constraints` checks the length. A post over 280 characters goes back to `Configure your influencer profile` and is written again.
5. `Post tweet` posts the text.

## Change the look

- The voice: `Configure your influencer profile`.
- The prompt: the system lines in `Generate tweet content`.
- How often: the interval in `Schedule posting every 6 hours`.
- The model: `Generate tweet content`.

## Good to know

- The workflow posts to a real account with no person checking it first. X's automation rules and its page on automated account labels, read on 12 November 2026, say an automated account carries the automated label and stays connected to a human-run account. Set the label if the account is automated.
- The example style says the posts are personal and share personal stories, so the model will invent them. Edit the style if you do not want invented stories presented as real.
- A post that stays too long is written again, with no limit on the tries.
- With X's pay-per-use prices, four posts a day add up. A post with a link costs far more than one without.
- This copy was not run against OpenAI or X.
- Your profile settings go to OpenAI, and the post goes to X.
- The JSON holds no credential.
