Overview

Sydium learns how you write by analyzing your existing social media posts - your tone, emoji usage, hashtags, vocabulary, even your signature phrases. Then it creates content that's indistinguishable from what you'd write yourself.

Three autopilot modes:
- Full Autopilot: AI creates and publishes without you
- Batch Review: review a week of posts at once
- Individual Review: approve each post

Publishes to 10 platforms: Instagram, TikTok, YouTube, LinkedIn, Twitter/X, Facebook, Pinterest, Bluesky, Threads, and Mastodon.

Also included: Image Studio (conversational AI image editing with per-platform resize), Video Studio (AI video generation plus trimming, captions and audio cleanup), a unified inbox for comments and DMs, AI reply suggestions in your voice, a Link-in-Bio page, YouTube thumbnails, and daily content ideas from what your audience is actually searching (Muse).

For power users and agencies: a public REST API, CLI and MCP server to control Sydium from AI agents, plus a white-label client portal.
