Syren

Syren is Synthesia's AI video agent that turns one prompt into a finished video. You describe the video, it writes that video as code and renders it in the browser, and you refine the result in chat.

Syren's page says the first video is free, with launch credits for one video that are valid for one month. Videos on the free plan include a watermark. A two-minute video with up to two rounds of edits typically uses 1,000 to 2,000 credits. Last checked 19 Oct 2026.
