🚀 Today, we made the difficult decision to sunset our most-requested feature. Here's why: 1) It distracted from our core mission. 2) It served only 3% of our users. 3) Maintenance cost outweighed value. Sometimes saying no is the hardest yes. What unpopular decisions have you made recently? 👇
Voice supplement
An AI clone that writes like you - and only like you.
How Sydium's Brand Voice AI ingests your existing work, builds a per-author profile, and ships posts your audience can't tell from your own.
Most AI writing tools sound like ChatGPT. They write competent paragraphs that read identically across every brand and operator. Sydium does the opposite: instead of imposing a generic voice on you, it captures yours - cadence, vocabulary, sentence rhythm, the things you do not say - and writes inside that frame. Your audience does not notice the handover because there is nothing to notice.
Your audience reads you because you sound like you. Sydium preserves that.
Section II
How the press learns your voice.
Three inputs, one profile, thirty seconds. The model is built from your actual material, not a generic template.
Input
Paste a URL, your posts, or both.
Drop a website link (we crawl your blog, your About page, your case studies) or paste 5-20 of your past posts. The more material, the sharper the voice.
Analysis
The model reads you for cadence and vocabulary.
Sydium runs cadence analysis, vocabulary fingerprinting, sentence-rhythm detection, persona memory, and tonal anchors. The result is a vector profile that is yours.
Output
Every generated post drafts inside your voice.
When Sydium writes a post for you, it generates inside your voice profile, not a generic LLM persona. Override anything, but most operators do not.
Section III
Side-by-side: ChatGPT vs your voice.
The same prompt, two outputs. The first is generic LLM English. The second runs through a voice profile we trained on a real founder's posts. Notice the difference in cadence, hedging, and how often each one resorts to a list.
Prompt
Write a LinkedIn post about why I shut down a feature most users wanted.
I shut down the feature most users said they wanted. Three reasons. It only got real use from about 3% of accounts. The maintenance burden was eating two engineers. And honestly, the people who wanted it loud were not the people paying us. The customers who pay us wanted something else entirely. If you wait until everyone agrees to kill a thing, you never kill anything.
Section IV
From the desk: voices we have cloned.
Three operators describe what changed when their AI clone could write like them.
Founder, Noi Producem Podcast
“I run 20+ podcast client accounts. Each has its own voice profile. The AI gives me a starting point that already sounds like the client. I spend three minutes editing where I used to spend forty writing from scratch.”
Mirela Pascu
Marketing, Lux Divina
“I do not waste hours figuring out what to post. Sydium drafts something that sounds like me, I adjust a sentence, publish. I post much more consistently now.”
Alina Stoian
Section V
Honest limits. What voice cloning is not.
We are not selling magic. Voice cloning is a constrained tool that works well inside its constraints and badly outside them.
Not a content strategist.
Sydium writes well in your voice once you give it a topic. It does not decide what your business should talk about. That is your job.
Not a journalist.
Voice cloning preserves your style. It cannot fact-check or invent expertise you do not have. Treat draft outputs the way you would treat a junior writer's drafts.
Not a fix for thin source material.
If you paste two posts written six months apart, the voice profile is thin. The model sharpens with more material. Five to twenty posts gives a usable profile; thirty or more is excellent.
Not a substitute for taste.
The clone preserves how you write. It cannot preserve how you choose what to write about. You still have to be interesting.
