Give xCinder one idea and the accounts that should publish it. The writer returns a separate post for each account, in the language of your brief, and keeps every draft inside a normal post.

The box is a brief, not the post
When Grok or GPT is the writer, the text you type is the assignment. It can be longer than a post, because it is instructions: the idea, the tone, the point that has to survive. The writer then makes a separate post for each account, and every one of those posts still has to fit the normal length.
The long-post control is for a person typing one post by hand. The writer does not use it. A verified badge does not raise the draft. If the instructions themselves run past 3,500 characters, the save stops and asks you to shorten them.
Grok, or your own GPT key
Grok can use the login of the account that is posting, another connected account you choose, or an xAI API key you save. GPT uses a key you bring. xCinder does not sell GPT credit. It can show what that key spent through xCinder during the month.
You can add writing instructions, such as tone or a point to include. Those notes shape the draft. They do not raise the length limit, and they do not change the language rule.
A different text for every account
The writer checks the draft against posts that account has already sent. If the opening matches, or too much of the wording is the same, it tries again. The composer also warns you when several accounts would publish the same text you typed yourself.
Each draft stays within 280 weighted characters. A link counts as 23. An emoji, or a Chinese, Japanese, or Korean character, counts as two. The composer has a long-post control for a person typing one post. The AI writer does not use that length.
If you want a thread, the writer can split the idea into a series of posts, up to 15, and each part still has to fit the normal limit. The image, if you attach one, goes on the first post.
Same opening, try again
The writer compares a new draft with what that account has already published, and with the last texts from this campaign. If the first words match, or too much of the wording is the same, it refuses the draft and tries again, with a different angle, and with a note about why the last one was turned down.
The language follows the brief. An Arabic assignment stays in Arabic. A thread, if you ask for one, is a series of posts up to 15, and each part still fits the normal limit. The image, when there is one, goes on the first post only.
You still decide what goes out
Read the draft before a schedule starts. The writer does not know your customers, and it will not correct a wrong fact you did not catch. xCinder is independent of X and of GPT.
