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.
