Mallary connects your social publishing workflow to ChatGPT. You can work with your connected social accounts without sharing an API key.
Mallary is available as a published ChatGPT plugin.

Add to ChatGPT

Open Mallary in ChatGPT and install the plugin.

​
Start in Three Steps

  1. Click Add to ChatGPT above, then click Install plugin.
  2. Sign in to Mallary and allow the connection.
  3. Start a ChatGPT request with @Mallary and say what you want to do.

​
What You Can Do

  • see connected social accounts
  • create or schedule social posts
  • use images you make or choose in ChatGPT
  • use a different message for each platform
  • check publishing status and open published posts
  • read comments and post approved replies
  • review post analytics
  • review follower and subscriber counts

​
How Sign-In Works

The Mallary plugin uses OAuth. ChatGPT opens Mallary in your browser and asks you to approve access. ChatGPT handles the connection setup. Mallary never gives the plugin your password, social account tokens, API keys, or payment details. You can review or revoke access from your Mallary account at any time.

​
Your Requests Control What Happens

Mallary only posts, uploads, or replies when you ask for that result. These actions are real. A post can go live on your social accounts. Check the profile, platforms, message, image, and time before you ask ChatGPT to post.

​
Make an Image and Post It

You can ask ChatGPT to make an image and post it with Mallary. You can also choose an image in ChatGPT. ChatGPT sends Mallary a short-lived link to the image you approved. Mallary checks the image, copies it to https://files.mallary.ai, and uses that Mallary link in your post. Mallary accepts JPEG, PNG, WebP, and GIF images up to 25 MB through this flow. This image tool is only for social post images. Do not use it for private customer files, health records, ID records, card details, passwords, API keys, or access tokens.

​
ChatGPT Plugin and Codex

The ChatGPT plugin is the quick way to use Mallary in ChatGPT. Codex uses a different setup through Mallary MCP, the CLI, or the Mallary skill.

​
Post a Video

Attach an MP4 or MOV video up to 512 MB in ChatGPT and ask Mallary to upload it for your post. Keep your approved captions in ChatGPT. Ask Mallary to use the attached video with those captions and your chosen accounts. Check the accounts, date, time zone, and platform choices before ChatGPT schedules the posts. Uploading alone does not publish a post. Anyone with the Mallary video URL can view the file. A client that can read your video file and send HTTP PUT requests can also use standard MCP’s video upload flow. Each social platform has its own video rules. LinkedIn requires MP4. Reddit does not support video uploads through Mallary. Mallary checks your selected destinations before posting and reports any problems.

​
Saved Drafts

Saved drafts are available to all users. Save unfinished posts without a publish date or a publishing job. Read, edit, or delete them, then publish or schedule when ready. A request to save a draft does not authorize publishing.
