Neda is 25, a fellow designer, born in my hometown. Since 2020 she has been living with an anaplastic astrocytoma, a grade III brain tumour. She’s been through surgery, radiation and twelve rounds of chemotherapy, and her latest MRI shows it growing again.

100% of what you pay for 4hands, after Stripe’s card fee, goes to Neda. Donations of any amount go through Pokreni život, a registered Serbian humanitarian organisation that runs her fundraiser and pays her treatment bills directly.

Because it’s in the open. The donate page shows what 4hands has raised so far, I post every transfer to her account on X and Instagram, @kosta4a, and her fundraiser on Pokreni život shows every donation.

Yes. Donate any amount on her fundraiser at Pokreni život, a registered Serbian humanitarian organisation. No purchase or account needed.

The current goal is $15,000. If she needs more, we raise it, and the donate page shows how close we are.

Yes. She’s on Instagram as @nederlon, and her own fundraiser is linked on the donate page.

4hands is a taste library for designers and developers who give a damn: lessons, live before and after demos, and agent skills. It’s everything I know about making software feel like someone cared, with the reasons written down, not just the results. I’m Kosta, founding designer at Steel, and I built it with Marko Zivanovic, an engineer.

Designers and developers who ship software and are tired of it looking like everyone else’s. Some lessons touch code, most don’t care whether you work in Figma or an editor. If you’ve shipped something and been unhappy with it, it’s for you.

Lessons, live before and after demos, and agent skills, in 7 collections: Thinking, Creative process, Applying skills, Agents without the fear, Collaborating with AI, Applying feedback and The kit. Thinking is out now with 5 lessons, and the other 6 come with the launch, December 14, 2026.

No. Some lessons touch code, most don’t care whether you work in Figma or an editor. The collection on agents is for designers who tried one once and closed the tab: you won’t type commands, you’ll type sentences.

It will. Two of the collections coming at launch, December 14, 2026, are about agents: one for getting started without the fear, and one on collaborating with AI, where you give the agent your decisions in writing and review what comes back like an editor. The agent skills install in one line, so your agent works by the same rules you do.

A library. There’s an order if you want one, starting with Thinking, but nothing is locked behind finishing something else. Read what you need when you need it, and come back to the demos and skills when you’re making something.

Whenever I learn something worth writing down, which is most weeks. Every lesson I add later is yours too. You paid once.

$100, once, while it’s on pre-order. On launch day the price jumps to $200.

No. One payment, lifetime access. No subscription, no tiers, no upsell, and every lesson I add later is yours too.

4hands isn’t out yet, so buying it now is a pre-order. You pay once, you read the 2 sample lessons now with your account, and on launch day, December 14, 2026, everything opens for you, along with your signed member card. Until then, be patient, 4hands is coming out soon!

Yes. Sign in, pay $100 once, and you’re set for launch day in December.

December 14, 2026. That day everything opens for everyone who pre-ordered: every collection, the demos, the skills and the member cards.

Yes. Sign up for free to read the first 2 lessons of Thinking: “Taste, a decision made with reason” and “Start with meaning, not pixels”. No card details needed. The other lessons show their opening, and open in full on launch day, December 14, 2026, for everyone who pre-orders.

Yes. Email contact@4hands.dev with how many seats, and I’ll sort it out.

Pre-orders and orders can be refunded on request: email contact@4hands.dev. You can’t get a refund once you’ve completed at least one category or actively used the skills provided. Donations go through Pokreni život, not 4hands, so we can’t refund them.

No. Donations go through Pokreni život, not 4hands, so we can’t refund them. Pre-orders and orders are different: those can be refunded on request, by email to contact@4hands.dev.
