The whole job, handled.
It learns your voice
From your own posts: cadence, vocabulary, point of view. The drafts read like you on a good day, not like a template.
It fills your calendar
Every platform, at the right time, drafted before you ask. You approve everything in one pass. Nothing ships without your OK.
It earns the keys
Start by reviewing every post. Move to one Sunday sitting. Hand it full autonomy when it deserves it. Pause is always one click.
“I train AI on brands for a living, so I am hard to impress: Sydium runs all my brands, and each one still sounds like itself.”
“I open it, adjust a few lines, and it goes out. That's the difference between posting when I have time and posting every week.”
“Found a missing feature. He shipped it the next day. I am no longer just a user, I am a supporter.”
“To do what Sydium does, I needed three things: a scheduler, a GPT I built myself, and an assistant to run them.”
Simple plans.

I built Sydium because I was the founder who never posted. Running the business always beat posting about it, so I built the teammate that never forgets. Now the queue is never empty and it still sounds like me.Dan Pralea · built solo in Brasov, Romania · support@sydium.com
