A post is the core unit of content in PostSider. It contains everything needed to publish a message to one or more of your connected channels - the text you want to share, any attached media, a scheduled time, and metadata like tags and groups. Every post you create lives in your PostSider workspace, where you can monitor it, edit it, and track how it performs after it goes live.

Anatomy of a Post

Each post is made up of several components that you can configure before scheduling:

Content Text

The written message for your post. You can write different content per platform or share the same text across all targeted channels.

Attached Media

Images, video, or audio files attached to the post. PostSider tracks media type (image, video, audio) and stores uploads in your Media Library for reuse.

Scheduled Time

The date and time the post will be published. Saving as a draft does not publish anything, but the post still carries a date used by the record and calendar. Pick a future time to place the post in the scheduling queue.

Target Channels

One or more of your connected channels. You select which platforms will receive this post when you compose it.

Tags

Labels you attach to a post for filtering, searching, and organizing your content library.

Post Group

A container that links related posts together - for example, the individual messages in a thread. Groups are managed together and can be deleted as a unit.

Post States

As a post moves through its lifecycle it passes through these states:

Publishing to Multiple Channels

One post in PostSider can target multiple channels simultaneously. When you compose a post, simply select all the channels you want to publish to. PostSider will send the content to each platform at the scheduled time. You can also customize the text for each individual channel if the platforms have different audiences or formatting requirements.

Post Groups

A post group is a collection of related posts managed together - for example, a Twitter/X thread where each tweet is a separate post but they all belong to the same group. When you create a thread or a multi-part update, PostSider automatically links the individual posts into a group. You can view, edit, and delete an entire group at once from the post list or calendar.

Duplicating Posts

You can duplicate any existing post to quickly create a new version without starting from scratch. When duplicating, you can:
  • Keep the same channel - useful for reposting evergreen content on a different date
  • Target a different channel - useful for cross-posting adapted content to a new platform
Duplicated posts are created as drafts so you can review and adjust them before scheduling.

Organizing with Tags

Tags let you label your posts with any keywords that are meaningful to your workflow - campaign names, content themes, client projects, and so on. Once tagged, you can filter your post list and calendar by tag to quickly find what you need. Tags are managed through the dashboard API (/posts/tags) and the public API’s tags field. There is no dedicated tag-management page in the dashboard.

Platform Character Limits

Every social platform enforces its own character limit. PostSider knows these limits and validates your content before you can schedule a post - if your text is too long for a target platform, PostSider will flag it so you can trim it before it fails at publish time.
If you have a long piece of content that needs to fit into a short-form platform, use the built-in AI assistant. It can automatically split your content into platform-appropriate chunks - perfect for turning a long LinkedIn article into a punchy X thread without manual trimming.
