THE BIG PICTURE
Synthesia Syren is an AI video agent within Synthesia that turns a text description, example, or supporting material into a rendered video while you watch. It is designed for fast, creative output such as launch videos, explainers, product walkthroughs, how-tos, marketing videos, and ads.
Syren writes the video as code, creates scenes, and lets you refine the result through chat instead of constructing every scene manually. It is distinct from Synthesia Studio: Syren prioritizes speed and creative design, while Studio provides tighter control for exact, repeatable training, compliance, onboarding, and internal-communication content.

WHAT YOU CAN DO
Get to know the capabilities. Find your own way to use them.
Describe the intended video in natural language, and Syren writes the script, builds the scenes, and renders a complete draft without requiring manual scene construction.
Add documents, images, videos, PowerPoint files, or YouTube links so Syren can use supplied material as context for the generated video.
Watch the video render in real time as Syren builds it, with a chat panel showing progress and a script panel displaying narration.
Ask Syren to change the script, avatar, voice, scenes, music, shot types, aspect ratio, or pronunciation after the initial video is generated.
Select headings, images, shapes, or other visible elements to move or retype them directly, with changes applied immediately.
The playhead position and selected element accompany chat requests, helping Syren apply an instruction to the specific moment or object you mean.
Choose wide 16:9 landscape for websites and presentations or tall 9:16 portrait for mobile and social feeds before generation.
Generate at Source, 720p, 480p, or 360p, then publish with link, SSO, password, or email-request viewing options.
MADE FOR YOUR WORKFLOW
Turn a feature description and brand material into a short launch reel using kinetic type, interface fragments, narration, and a selected portrait or landscape format.
Provide documentation, screenshots, or a product outline and refine the generated script, scenes, voice, and pacing into a practical guided explanation.
Create a concise recap after a demo that revisits the discussed product points, connects them to a prospect’s needs, and closes with a next step.
YOUR FIRST STEPS
Select Syren under Tools in Synthesia, or connect Synthesia in Claude when creating a video through that connector.
Select Wide 16:9 or Tall 9:16 before entering the prompt. Example videos use their preset shape instead.
Write the subject, audience, tone, visual style, narration, and music direction, then optionally attach supporting files or links.
Watch the live build, then use chat or direct editing to adjust wording, avatars, voices, scenes, elements, music, or pronunciation.
Choose a resolution, generate the finished file, and publish it using the available viewing controls such as a link, password, SSO, or email request.
