thecornercafe 🚀 Exciting news, coffee lovers! ☕ We are THRILLED to announce our brand-new Summer Menu, crafted to elevate your coffee experience! Unparalleled flavors await. Don't miss out! ✨ #CoffeeLovers #SummerVibes #Blessed

what every other tool writes

drag the lime line left. then prove it on your own words.

Same engine, whatever the business.

There are no industry templates in here. Sydium reads what you already publish and writes the next post in that voice - which is why a skincare brand and a skate shop end up with nothing like the same words.

1

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.

2

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.

3

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.

What comes out the other end

One idea, three finished pieces. Vertical video with the captions burned in, a carousel written slide by slide, and a long post that sounds like you. Each one sized for where it lands.

We went quiet for four months. Nothing broke. The phone just rang less, one week at a time. That is the part nobody warns you about: going quiet is never dramatic. It is gradual. We started again in March. One post a day, same shop, same work.

Long-form that sounds like you. Written from what you have already published, not from a prompt you had to invent.

the sounds-like-you promise

If your first month doesn't sound like you, we retrain your voice free and refund the month.

No form. No call. Email us and it's done.

Covers your first paid month, on top of the 14-day free trial. You are the judge.

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
