Make and post your marketing from ChatGPT

Add Siren to ChatGPT as a custom connector. Describe the post, and Siren makes an on-brand film or image, writes the caption and publishes it to your social channels.

You already think out loud in ChatGPT. Add Siren as a connector and the idea you just talked through becomes a finished film or image in your brand, posted to X, LinkedIn, TikTok or YouTube.

Add a custom connector

https://mcp.mysiren.ai/mcp

In ChatGPT open Settings, then Apps & Connectors, then Create.
Paste the URL and approve once at app.mysiren.ai/connect.
Connect your channels in the Siren dashboard and turn on Allow posting.

From a conversation to a post

Talk through the launch with ChatGPT the way you normally would. When it sounds right, say make it. ChatGPT sends Siren the brief, Siren renders a film or still from your Brand DNA and writes the caption. Say post it and it goes out, or give it a time and it waits.

Prompts to start with

We just launched team invites. Make a short film for X and LinkedIn.
Make three stills for this week, one per feature we shipped.
What does our Brand DNA say our tagline is? Change it to this.
Post the last run to X now.

Why not just ask ChatGPT for an image?

A general model does not know your brand, so every image looks like a different company, and it cannot post for you. Siren keeps your colors, type, logo and voice on every render and publishes to the channels you connected.

FAQ

Which plan do I need?

Pro or Scale. Spark cannot connect an agent.

Is my brand shared with OpenAI?

ChatGPT sees what the tools return, like your Brand DNA fields and run links. Rendering happens on Siren.

Can it post without me?

Only after you turn on Allow posting. Until then it can make assets but not publish them.

What does a film cost?

25 credits. A still is 10. Pro includes 300 credits a month.
