Sydium

Sydium is an AI social media manager that learns how you write, then handles everything.

Unlike scheduling tools where you still create everything, Sydium's AI analyzes your existing posts to learn your tone, emoji usage, hashtag style, and signature phrases. Then it creates content that's indistinguishable from what you'd write yourself.

What sets Sydium apart:

BRAND VOICE AI The AI learns from your existing content across platforms - extracting your tone, vocabulary, emoji patterns, and hooks. Result: AI-generated content that sounds like YOU, not generic AI.

AI AUTOPILOT Fully autonomous social media management. AI creates, schedules, and publishes automatically. Choose full autopilot (zero touch), batch review (approve once a week), or individual review (approve each post).

IMAGE STUDIO & VIDEO STUDIO Conversational AI image editing with per-platform resizing, plus AI video generation, trimming, captions, and audio cleanup - so your visuals are handled too, not just the words.

MUSE - Daily Content Ideas Never stare at a blank screen again. Muse delivers daily content ideas based on what your audience is actually searching in your niche. One click to generate a full caption in your voice, and it can feed straight into Autopilot.

PUBLIC API, CLI & MCP A public REST API, a CLI, and an MCP server let you drive Sydium from your own tools or from AI agents.
