What can you do with ChatGPT and Publer?

Once connected, you can ask ChatGPT to:

• Create posts and drafts using text, images, videos, links, carousels, polls, Reels, Stories, and other supported post types.
• Schedule, AutoSchedule, publish, recycle, or set up recurring posts for one or multiple social accounts.
• Upload and use media from your Publer Media Library or files shared directly in ChatGPT.
• Add supported post options, such as first comments, follow-up comments, AutoShare, watermarks, signatures, locations, labels, albums, and Pinterest boards.
• View and manage connected social accounts, workspaces, scheduled posts, drafts, published posts, and media.
• Edit or delete supported posts.
• Check analytics, analyze recent performance, and view competitor data where supported.
• Generate content ideas, captions, and publishing suggestions.

For example:

Create a LinkedIn post about our latest product update, add this image, and save it as a draft in Publer.

Or:

Create 5 Instagram posts and AutoSchedule them for next week.

Or:

Show me my recent Facebook performance and suggest content ideas based on the results.

ChatGPT will use Publer's MCP tools to complete your request based on your account permissions and the features supported by each social network.

Keep in mind:

• ChatGPT can only perform actions supported by Publer's MCP.
• The same social network requirements and limitations that apply in Publer also apply when using ChatGPT.
• Always review the social account, content, and scheduling details before publishing important posts.
• You can disconnect Publer from ChatGPT at any time through the Publer plugin's connection settings.
