X (Twitter) scheduler

Schedule X (Twitter) posts and threads

Postoni is an X scheduler for people who would rather write a thread on Monday than babysit it on Thursday. Draft once, trim it to 280 characters for X while your LinkedIn version stays long, and pick the minute it goes out. Threads, articles and reply settings are all handled in the same composer.

Built around how X (Twitter) actually works

  • Threads that post in order

    Add each reply as its own box in the composer. Postoni publishes the first post, then chains the rest underneath it at your scheduled time.

  • Control who can reply

    Choose everyone, people you follow, mentioned users, subscribers or verified accounts for each post. Handy for announcements where you want fewer drive-by replies.

  • Repost and plug on autopilot

    Optional rules can repost a post once it reaches a like count you set, or add a reply with your link when it starts to take off.

How to schedule a X (Twitter) post

Four steps, about two minutes the first time. After that it's write, tweak, schedule.

  1. 1

    Connect your X account

    Click X in Postoni and approve access on X. You connect whichever account you're logged into, so switch accounts on X first if needed.

  2. 2

    Write and trim your post

    Start from your shared draft and tighten it for X. The live counter shows exactly how much room you have left.

  3. 3

    Pick X settings

    Set who can reply, post into a community by pasting its link, or switch to article mode with a title and cover image.

  4. 4

    Schedule or add to queue

    Choose a time on the calendar in your own time zone. Postoni posts it and keeps the link so you can check results later.

X (Twitter) character counter

Check a draft against the 280-character limit before you post.

Character counter for every network

Paste one draft and see which networks it fits.

Does Postoni publish automatically to X?

Yes. Once a post is scheduled, Postoni publishes it through the official X API at the time you chose. You don't need a browser tab or phone open. If X rejects a post, for example as a duplicate, you get a notification with the reason.

What is the X character limit in Postoni?

280 characters for standard accounts. If you have X Premium, tick the verified option when you connect and the limit goes up to 4,000. Articles are long-form and have no practical cap.

Is there anything on X Postoni can't schedule?

Polls and Spaces aren't supported through the API, so those still happen in the X app. Draft articles also can't carry thread replies, because there is no live post to reply to yet.

Can I schedule X articles?

Yes. Switch the post type to article, add a title and an optional cover image, and choose whether X saves it as a draft or publishes it. Images go inline inside the article body.

Pairs well with X (Twitter)
