How to schedule X posts

X schedules posts itself, for nothing, and for a lot of people that is the whole answer. Here are those steps, from X's own help pages, first. Then the way that also covers your other networks, then the way your own agent does it.

1. The X way, with no tool at all

The calendar icon at the bottom of X's compose box, on the web.

  1. 1

    Open the compose box at the top of your Home timeline, or click the Post button.

  2. 2

    Write the post, up to 280 characters, and attach up to 4 photos, a GIF or a video.

  3. 3

    Select the calendar icon at the bottom of the compose box and make your schedule selections, then select Confirm.

  4. 4

    Find drafts and scheduled posts again under Unsent posts in the compose box.

X's own scheduler is enough when

One handle, scheduled from a laptop, and you do not mind the posts living only inside X.

  • Web only in practice: X's own article documents the calendar icon on the web compose box.
  • One account per browser session, so several handles means signing in and out.
  • No queue, no slots, no reply scheduled with the post.

Read from X Help Center: How to post on . Platforms move menus; the source is the place to check.

2. The free way, when one network is not the whole job

The native scheduler stops being enough the moment a second network is involved, or the post needs a first comment, or you want to see the week rather than one post. Our free plan is 10 posts a day across every network you connect, with no card.

  1. Connect X once, under Accounts, through X's own sign-in. No developer app, no key.
  2. Open Manual, pick the X account and write. Pick more accounts, and edit any preview where that account should say it differently.
  3. Add to queue takes the next free slot for that account, Schedule pins an exact minute, Post now sends it. Calendar shows the week.

Scheduling and publishing never spend credits. The $5 refilled each month is for the agents that write, design and render, which is the difference between this and a queue.

The per-network rules, and what happens when a draft breaks one, are on the free X scheduler page.

3. From an agent, on the same free plan

Add our X MCP server to Claude or ChatGPT and ask in plain words, or call the REST API or the CLI with a scoped key. Same queue, same cap, same approval.

REST
curl -X POST https://shapelessai.com/api/posts \ -H "Authorization: Bearer $SHAPELESS_API_KEY" \ -H "Content-Type: application/json" \ -d '{"connectionId":"CONNECTION_ID","postText":"Rebuilt onboarding. The first thing that broke was the part we were proudest of.","queue":true,"firstComment":"The full write-up, if you want the detail."}'
MCP tool call
{ "name": "posts_create", "arguments": { "connectionId": "CONNECTION_ID", "text": "Rebuilt onboarding. The first thing that broke was the part we were proudest of.", "queue": true, "firstComment": "The full write-up, if you want the detail." } }
CLI
shapeless posts create --to CONNECTION_ID --text "Rebuilt onboarding. The first thing that broke was the part we were proudest of." --queue --first-comment "The full write-up, if you want the detail."

Swap "queue": true for "scheduledAt": "2026-09-20T09:00:00Z" to pin an exact minute; leave both out and it publishes now.

Questions

Can you schedule X posts without a third-party tool?
Yes. The calendar icon at the bottom of X's compose box, on the web. It starts with: Open the compose box at the top of your Home timeline, or click the Post button. That is enough when one handle, scheduled from a laptop, and you do not mind the posts living only inside X. Steps read from X Help Center: How to post on 2026-09-14.
Can an AI agent schedule my X posts?
Yes, on the free plan. Add https://shapelessai.com/mcp to Claude, ChatGPT or any MCP host and the posts_create tool schedules through your connected X account, or call POST /api/posts with a scoped key, or run the CLI. Publishing tools are flagged so the host asks you before anything goes out.
Can I schedule a first reply on X?
Yes. Pass firstComment on the post and we publish it as a reply on the post once it is live, up to 280 characters. Platforms that have no such thing answer 422 rather than silently dropping it.
What does the free plan cost me later?
Nothing for the rail. Scheduling and publishing never spend credits. The $5 refilled each month is for the agents that research, write, design and render - a paid plan refills more of it and lifts the daily cap.

Schedule X and everywhere else from one place, free, 10 posts a day.
