Why use it

X (Twitter) scheduling without another isolated workflow.

Use the same calendar, approvals and publishing workflow you already use for the rest of your social stack.

Queue X posts ahead of time instead of depending on real-time manual publishing.

Keep short-form campaign copy visible next to LinkedIn, Threads, Bluesky and the rest of your social plan.

Use the same publishing layer for manual scheduling, API workflows and AI-agent automation.

Workflow

From draft to published in one queue.

Step 1

Connect X

Add the X account to PostSider and keep it in your existing workspace.

Step 2

Write the channel variant

Prepare the X-specific copy, review it against the platform constraints and choose a time.

Step 3

Schedule and move on

Humans + AI agents

Use the calendar yourself or publish programmatically.
