About Sydium
Sydium for ChatGPT connects your existing Sydium workspace - it requires an active plan or trial, and connecting doesn't start one (plans are managed at sydium.com). Once connected, ChatGPT can draft captions the way you actually write (learned from what you have already published), schedule or publish to up to ten platforms (Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, Bluesky, Threads, Mastodon), check how posts performed, pull today's content idea, and manage the upcoming queue - edit, reschedule, or cancel anything still scheduled. Agencies can act for individual clients with the same team-scoped permissions as the Sydium app. Publishing actions are explicit: ChatGPT confirms before anything lands on a public feed.
