Gen-Z Brand Voice + AI Content QA / EN + PL

Your brand.
In human words.

I rewrite awkward, corporate, or obviously AI-generated copy into a clear brand voice. Websites, social posts, and ads. English + Polish.

48-hour turnaround · fixed pricing · no long-term contract

01 / the disconnect

your visuals say Gen Z.
your copy says marketing department.

The design gets it. The words are still waiting for approval from six departments.

Generic AI phrasing. Slang that arrived a year late. Social captions with the warmth of a quarterly report. Hooks that take three sentences to get to the point.

If your captions sound like someone studying Gen Z from a distance, your audience notices. I help your site, social posts and ads sound like the same human brand — without dressing every sentence in a trend.

02 / fixed scope, clear price

A sharper voice.
A manageable sprint.

For startups, apps, ecommerce, gaming, consumer brands and creators building businesses.

03 / Spec work / unsolicited examples

before / problem / after

Fictional brand examples to show how I think. These are not client projects or measured results.

Everyday essentials

Before
Elevate your everyday routine with our must-have essentials.
Problem
Generic lifestyle language that could belong to almost any brand.
After
The stuff you’ll somehow end up using every single day.

A planning app

Before
Unlock seamless productivity and revolutionize the way you manage your tasks.
Problem
Big promises, no useful detail. The reader still has no idea what the app does.
After
Too many tabs open in your brain? Put your tasks in one place.

A clothing brand

Before
Hey besties! Our game-changing fits are giving main character energy.
Problem
Borrowed internet language does all the talking. The clothes get none.
After
Good jeans. Real pockets. Plans optional.
04 / how it works

You send it.
I make it sound like you.

  1. Send me your site, social posts or content.

  2. I audit tone, weak copy, AI-isms and cultural fit.

  3. I rewrite and build a mini voice system.

  4. You get the finished sprint pack within 48 hours of sending the material.

05 / what I look for

The small things
that make copy feel off.

  • Generic AI wording
  • Forced slang
  • Unnatural Gen-Z language
  • Corporate filler
  • Weak hooks
  • Inconsistent voice
  • Overexplaining
  • Copy that sounds translated rather than native
  • Awkward English / Polish localization
06 / a mini voice system

A voice you can reuse.

An illustrative starting point, adapted to your brand and audience. Useful rules for the next caption, not a manifesto nobody opens.

Sounds like

  • Conversational
  • Internet-aware
  • Confident
  • Specific
  • Playful when appropriate

Doesn’t sound like

  • Corporate
  • Fake-young
  • Try-hard
  • Generic
  • Overproduced

Leave these out

  • Unlock
  • Elevate
  • Embark
  • Revolutionize
  • Seamless
  • Game-changing
07 / another pair of eyes

for agencies too

I can work as a white-label Gen-Z / AI-quality layer before copy goes to your client.

Async collaboration, one-off reviews or ongoing support, in English and Polish. Especially useful for agencies serving younger audiences who want a careful check before the work leaves the building.

08 / Mateusz Nowak

Language first.
Trend-chasing optional.

I work in AI evaluation and quality-focused model training, where reading closely and judging language are part of the job. I bring strong English and Polish, an interest in internet culture, and attention to how online language actually changes.

The aim is natural language that fits your brand. Sometimes that means a playful line. Sometimes it means removing the slang entirely. English ↔ Polish cultural localization is available where relevant — so the meaning travels, not just the words.
