Synthesia launches Syren agent that learns your brand's motion style
lmoroney · x · 2026-10-10
Synthesia launched Syren in beta, an AI video agent that builds complete videos—motion graphics, avatars, voiceover, music, b-roll—from a prompt, preset, or existing document/image/video, with live preview and chat-based refinement.
Its Brand Kit learns colors, typography, animation style and pacing from your existing videos. Every user gets 2,000 Syren credits expiring November 9; basic plan videos are watermarked. The author suggests feeding it 2-3 of your best videos and verifying all avatar lines and on-screen numbers before publishing.
