Siren MCP · ChatGPT
Make and post your marketing from ChatGPT
You already think out loud in ChatGPT. Add Siren as a connector and the idea you just talked through becomes a finished video or image in your brand, posted to X, LinkedIn, YouTube or TikTok (with your OK on each post).

Talk through the launch with ChatGPT the way you normally would. When it sounds right, say make it. ChatGPT sends Siren the prompt, Siren renders a video 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 video 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
Straight answers.
Which plan do I need?
Any plan, Spark included. Videos are the one thing that needs Pro or above.
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 video cost?
25 credits. A still is 10. A platinum video for a big launch is 50. Pro includes 300 credits a month.
