X Posts by Content Mill
Draft and schedule X posts
X Posts by Content Mill is an X post scheduler for connected X accounts in your AI. Plan short updates for X, formerly Twitter, write post copy, save drafts, prepare photos, GIFs or video, preview the exact result, and schedule or publish only after approval. The plugin connects to Content Mill and works only with X accounts you have linked to your Content Mill account. Plan and draft X posts: Turn a launch, event, announcement, product update, community message, or behind-the-scenes idea into concise copy for your X account. Ask your AI to list your connected X accounts and check their connection status before choosing a destination. Save a text-only draft or add supported media to review later. Saving a draft never sends anything to X. You can inspect a draft and update its text, media, or target X account while it is still a draft. Write within X posting limits: Content Mill can return the current text, image, GIF, and video requirements before you compose. The server limits X posts to 280 characters and validates the copy before creating a draft or preview. Text-only posts are supported, so media is optional. If a proposed post is too long or its media is unsupported, revise it based on the returned reason. Check the server's current limits rather than assuming every file or format will work. Prepare images, GIFs, and video: Add supported media from a public HTTPS link, or upload a file from the conversation to Content Mill. The service checks file type, size, image dimensions, and video properties before a post uses the file. An X post can include up to four images, one GIF, or one video; these media types cannot be mixed in a single post. JPEG, PNG, and WebP images are supported by the server's X rules. Ask for the platform limits before writing media-heavy content, then use the hosted media URL returned by the upload workflow in your draft or preview. Schedule X posts with approval: Choose a connected X account and a future date and time with a clear time zone, or prepare a post for immediate publication after approval. Content Mill validates the destination, copy, media, and schedule, then creates a preview showing exactly what would go out and when. Your AI must show you that preview and wait for explicit approval. If you change the words, account, image, GIF, video, or time, it must create a new preview. The preview token is single-use. A draft or preview alone does not publish anything. Track your X posting schedule: Ask which posts are drafts, scheduled, publishing, published, or failed. List recent posts, open one to see its text, target account, media, and scheduled time, and check the live X link when the service returns it. Publishing is asynchronous, so a newly approved post may first appear as Scheduled or Publishing before its final result is available. You can remove a draft or cancel a scheduled post before it goes out. Published posts cannot be edited or removed through this plugin. Try prompts such as: ‘Which X accounts are connected?’ ‘Write a short launch post and save it as a draft.’ ‘What are the X character, photo, GIF, and video limits?’ ‘Schedule this image and post for tomorrow at 09:00 UTC; show me the preview and wait for my approval.’ ‘What X posts are scheduled this week?’ ‘Did my latest X post publish?’ These requests cover X post writing, media preparation, scheduling, approval before publication, and post-status review using connected accounts and actual tool results. Built for creators, social media managers, small businesses, agencies, and teams who want an X posting workflow in conversation. The plugin handles post creation and status for connected X accounts. It does not read or send direct messages, manage replies or comments, create ads, provide audience analytics, or access accounts on other social platforms. A Content Mill account and connected X account are needed for account-specific actions. Content Mill is independent and is not affiliated with or endorsed by X.
