Siren makes launch videos and ad creatives in your brand from one prompt, and posts them to X, LinkedIn and YouTube (TikTok with your OK on each post). One video is $9.99; plans are Spark $19, Pro $49 and Scale $149 a month, and Siren works inside Claude, Cursor and ChatGPT over MCP. Updated 28 Oct 2026.
Creatify is built for paid ads with AI actors: paste a URL, pick an avatar, launch to Meta or TikTok. Siren is built for a software brand posting every week: videos of your product in your Brand DNA, captioned and posted to your channels.
The cut
Pick Creatify when you are running paid ads and want a person on screen. Pick Siren when you are a software company that needs on-brand launch and feature videos posted to X, LinkedIn and the rest.
