Sydium trains a Brand Voice model on your existing posts (your tone, vocabulary, hashtags, emoji habits, and signature phrases) so generated content reads like you wrote it. Its AI Autopilot then drafts and publishes posts on a schedule you control - full auto, weekly batch review, or approve each post - adapts each post per platform, suggests replies to comments and DMs in your voice, and generates images and video.
