Siren vs InVideo
InVideo is an AI video studio: describe a video, it writes, generates with models like Seedance, Sora and Kling, and you edit on a timeline. Siren takes a different route: each video type is motion design written in code, filled with your brand and screens, so the same prompt gives the same video.
The cut
Pick InVideo when you want generated footage and a full editor to shape it. Pick Siren when you want a product video that shows your real brand and screens, the same way every time.
