- 20 AI-written posts a month
- All 9 social platforms
- Unlimited scheduling
- Basic analytics
Built in Brasov by a founder who used to hate posting.
The empty content calendar has been declared dead.
An AI trained on your past posts writes, schedules, and publishes new ones to 9 platforms, sounding like you. Approval optional.
You meant to post this week. You did not. You meant to post last week and the month before that. Your competitors are louder than you on every platform that matters. Sydium learns your voice, runs the press while you run the business, and refuses to let the calendar go blank again.
You will never batch content this weekend.

How the issue gets made
The morning run: editions filed, set, and folded. Every paper is the same paper, until it isn't.
Connect the wires.
Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, Threads, Bluesky. The whole stand at once.

The press learns your voice.
Cadence, vocabulary, boundaries, point of view. Your fingerprints, captured.

The empty calendar is the problem. Sydium fills it.
The presses run on their own.
Approve every issue, batch by week, or hand it the keys. The empty calendar is not coming back.

Every post crosses your desk first - until you say otherwise.
Approve, edit or skip each post - your call. One switch pauses everything. Every AI action is logged in the audit trail.
Review every post
Nothing publishes until you approve, edit or kill it. Start here.
Approve by the week
Sign off a whole week's queue in one sitting, then move on.
Full autopilot
It writes and ships on its own. Flip here once it has earned it.
Start in Review. Move to Autopilot when you trust it. Emergency pause is always one click away.

Sydium is for the founder, agency, or operator who needs to ship nine platforms a week without writing nine posts. If your bottleneck is bulk import, buy a scheduler. If your bottleneck is consistency, this is the press.

“I have been using Sydium for almost a month for our podcast clients. I have connected 20+ accounts and created voice profiles for each. The AI gives me a good starting point. I sometimes edit it, but it saves me from the blank page.”

On hours returned
“With Sydium I do not waste hours figuring out what to post. The AI makes me a draft, I adjust it in a few minutes and publish. I post much more consistently now.”
