Frequently asked questions

Do I need to be tech-savvy?

No. We explain everything in plain language, step by step, on your own materials.

How do I get the tool?

Right after payment you get a download link: on the confirmation page and by email. If nothing arrives within a few minutes, check your spam folder or write to hello@pnklab.com.

Which software do the spreadsheets need?

Microsoft Excel (2016 or newer), Google Sheets or Numbers. The spreadsheets are in Polish.

Will I get an invoice?

Yes. PNKLab issues a VAT invoice automatically after payment. Businesses: enter your VAT number at checkout.

Is it a subscription?

Spreadsheets and bundles are a one-off purchase. PicPalette has a free plan and paid monthly or yearly plans.

Can I get a refund?

You get the files instantly, so at checkout you agree to immediate access and lose the 14-day right of withdrawal. If a tool doesn't work as described, write to us: we will fix it, and if that's not possible, reduce the price or refund you.

How long does implementation take?

Tools work right away. Marketing usually starts within 1–2 weeks.

Will AI publish anything without my approval?

No. Every post, ad and message waits for your approval.

Do you work with businesses outside Poland?

Yes. The website and the PicPalette app are in English; the spreadsheets are in Polish for now.

Founder of PNKLab

For 16 years I have worked in real estate and property development: in marketing, sales and directly with clients. I also worked as an interior designer, designing my own investment properties and taking on client commissions, so I know this job from the inside.

I run campaigns and content for businesses, and I build AI tools the way I would like to use them myself: simple, with a filled-in example and ready AI prompts.

I study artificial intelligence in business at SGH Warsaw School of Economics.
