I’ve spent twenty years trying to make my own brain work better. Co.Actor is what happened when that habit met ChatGPT.

The short version

I read everything, scribble notes everywhere, and have a low-key fear I’ll start forgetting things one day. Not in a dramatic way — but enough that I always wanted some kind of external memory I could trust. I’ve been hacking at that problem in different shapes for about twenty years.

After I exited my last business in 2020, my family and I moved to Koh Samui for what was supposed to be a long break. I thought I’d rest. Instead I started feeling worse the longer it went: nothing serious to think about, days blurring together, and the old worry coming back — if I stop using my head hard, I’m going to lose it.

When ChatGPT showed up

I went straight back to work. But I had no patience for chat windows that forgot me five minutes later. I wanted the part underneath — the bit that turns words into numbers so a machine can compare meanings instead of just letters. That trick is called vectorization, or embeddings. I’m not a math person, but the idea hit me hard: you can store the meaning of everything you’ve ever written, and search it back later by what you actually meant, not by the words you happened to use.

I built a tiny prototype on Koh Samui. Two Telegram bots. The first one swallowed everything I wrote and stored it as embeddings. The second one let me ask questions, and answered using only what I’d written before. It worked. I could ask a half-formed question at midnight and get my own past thinking back in a better shape than I’d originally left it.

The phone call that started Co.Actor

I put about a thousand dollars into ads for a Telegram channel where I posted my AI experiments. The channel grew to a thousand readers in a couple of months. One of them was Max Votek, who runs a B2B integrator in Florida. He flew out to Koh Samui to meet me.

He tried the bot on his own LinkedIn posts — asked it the kinds of questions people had been asking him for years. He looked up and said something I still remember word for word: “Serge, these are my thoughts, but I wouldn’t have phrased them this way.”

That was the moment. We realized the same trick — record what someone actually thinks, store it as meaning instead of words, replay it on demand — could let an entire team ship content in their own voice without anyone having to carve out time to write. Max said, “if you can get ten people in my company posting regularly, I’ll pay you ten thousand dollars a month.” I built it. That’s Co.Actor.

Where we are now

The team moved from Koh Samui to Boca Raton, Florida in 2025. We’re six people building Co.Actor and Publora out of one studio, all of us treating AI agents as co-workers rather than tools. The original fear — losing my edge — hasn’t gone away. It turned out to be a useful one. It’s the same problem I’m now solving for other people: how do you keep what’s in your head from disappearing, and put it to work?
