How to post to X from ChatGPT
X is short and fast, which suits ChatGPT well: a hook, a thread, a reply-ready tone. This guide shows how to go from an idea to a scheduled X post or thread, with SimplePost checking X's weighted length for every post.

Quick answer
Can ChatGPT post to X (Twitter)?
Yes, through SimplePost. Connect your X account in SimplePost and install the SimplePost plugin in ChatGPT. ChatGPT can then publish or schedule single posts and threads, which SimplePost posts as a reply chain.
Before you start
What you need
- An X account. Posts longer than 280 weighted characters need an account X allows to publish long posts.
- A SimplePost account on the free trial or a paid plan.
- ChatGPT with access to apps in your plan or workspace.
Workflow
Step by step: how to post to X from ChatGPT
Connect X in SimplePost
Open Accounts → Connect account → X and approve access for the account you want to post from.
Install SimplePost in ChatGPT
Install the plugin from its ChatGPT listing and sign in with the same SimplePost account.
Ask for a post or a thread
Tell ChatGPT the format. For a thread, ask for a hook and a number of follow-ups, each under 280 characters.
Prompt List my SimplePost accounts. Turn this into an X thread: a hook post and three follow-ups, each under 280 characters, no hashtags. Topic: what we learned shipping offline mode.
Preview the thread
The preview shows the chain in order. If one post is too long, SimplePost says which one, counting links as 23 and emoji as 2.
Prompt Show me the X preview.
Schedule
Give the time and timezone. SimplePost stores the thread and publishes the posts in order at that time.
Prompt Schedule it for tomorrow at 09:00 America/New_York.
Check the result
Each post in the thread gets its own result, so you can see a partial failure.
Prompt Show me the result for each post in the X thread.
Before you schedule
Check these details
- Each post is within 280 weighted characters, unless your account can post long posts.
- Only one $cashtag per post.
- Media is on the first post (up to 4 images, or one video).
- The time and timezone are correct.

Troubleshooting
If something gets in the way
"Requires Premium"
X reported that the account cannot publish long posts. Split the post into a thread or shorten it.
A reply or quote was rejected
X's API rejects replies and quotes to posts that are not yours and do not mention you.
The thread partly failed
Inspect the post in SimplePost; the per-segment results show where it stopped.
