Cătălin — AI marketing agent

Writes copy, subject lines, ad variants, and social posts, all in your brand's voice.

The marketing agent knows what you sell, who you sell to, and how you talk, then turns out variants in seconds: 3 angles for an ad, 5 subject lines for an email, 10 posts for next month. Written to your brief, not generic filler.

A prepared conversation, so you can quickly understand how it can help.

I'm Cătălin. Tell me briefly what you sell and who it's for, and I'll suggest a few lines.
We have an online course for people who want to organize their money and save for their first home.
Got it. What do you want someone to do after reading the page: leave their email, buy the course, or ask for more details?
Leave their email so they can get the first lesson for free.
Here are 3 simple, friendly headline options: 1. Clear and direct: "Learn to organize your money without complicated spreadsheets." 2. With a concrete goal: "Save for your first home, one step at a time." 3. Warmer: "The first step toward your own place starts with the money you already have." I'd start with option 2 because it makes the benefit clear right away. Want me to write the short text under the headline too?

Productivity

An AI agent vs. hiring someone for the same work

The agent isn't a replacement for people. It takes the repetitive work off their plate, so your team handles what actually needs judgment. Here's what that looks like in numbers.

Common questions

The questions we hear most

Straight answers on how we set each agent up inside your business.

How does the agent learn our brand voice?

In the first week we feed it 20–50 pieces of copy you've already approved, plus your brand guidelines, banned terms, and a few examples of "too generic". It does lightweight fine-tuning on that corpus; in practice it drifts less than 5% from your style.

Can it publish straight to our channels?

Yes, through Buffer, Hootsuite, HubSpot, Mailchimp, or Klaviyo. Honestly though, we recommend a human review step for the first 4 weeks. The feedback from that period is what lets us tune the prompts properly.

Does it work in multiple languages?

Yes. We write natively rather than translate, in EN/RO/FR/DE/ES/IT, keeping the tone. For other languages we run a separate quality check first; we don't promise quality we haven't verified.
