What is a social media scheduler?

Definition: A social media scheduler is software that lets you write posts in advance and publishes them automatically to your social accounts at the times you choose.

Also called: social media scheduling tool, post scheduler

Updated October 10, 2026

How it works

You connect each social account through the network’s official sign-in (OAuth), so the scheduler never stores your password. At the scheduled time, it sends the post through the platform’s official API.

What to look for

  • The networks you use (and the formats on each, such as carousels or Reels)
  • A calendar view across all platforms
  • A version of each post per platform, not one text for all
  • Team approvals if more than one person posts
  • Analytics per post and per platform
  • An API or MCP server if you want AI assistants or automations to use it
Example

Postprism publishes to X, Bluesky, LinkedIn, TikTok, YouTube and Pinterest from one calendar, with a version per platform and optional AI to adapt each one.
