I only build what I'd buy myself.
No smoke. If I wouldn't recommend a tool or course to my best friend, it doesn't ship. Sounds obvious. Isn't.
Diexar — a small studio by Eric Dieperink
I build tools, programs and voices people actually use every day.
Five projects. One obsession: making things that are simple, fairly priced, and don't need a manual. No growth hacks. No hype. No jargon my mother frowns at.
How I work
Three rules. That's all I have.
I come from a time when a product either worked or it didn't. I miss that. Which is why I hold myself to these three rules — on every project I build, every euro I charge, and every email I answer.
If I can't explain it to my mother, the concept is wrong.
Simplicity isn't a "feature". It's the whole job. Once someone in their 70s gets it, I'm done.
No noise. No sales tricks. No "47 free bonuses".
Clear prices, honest promises, products you can just open and use. Beyond that, I shut up.
The work
Five things I build every day.
One program, two pieces of software, one voice, and one open-source experiment. All under the same roof.
01 Program
AI Money Code 50+
ai-geld-code-50plus.nlThe program I wish existed when I started. A calm, step-by-step path teaching people 50+ how to build their first digital income with AI — alongside their job or retirement.
One participant called it "the first online course that spoke my language". That's why I do this.

AI ListGuard
inside the blueprint
AI Money Code 50+ members only
Twelve online tools that keep your email list safe, clean and deliverable. Bounce analysis, DNS checks, spam scoring, disposable-email detection — all in one place.
No separate subscriptions. No spreadsheet tombstones. Just a bounce rate that stays sane and mail that doesn't land in spam.

03 Voice-over
Voiceactor
stemacteur.lifeDeep, cinematic voice-overs for commercials, audio guides, e-learnings and games. Dutch or English. Home studio.
Call or email; I'll send a demo the same day — with your own script, not a generic reel.

04 Software
License Keys
licentiesleutels.nlReal Microsoft licenses — Office, Windows, Project, Visio, Server — delivered to your inbox within five minutes. With invoice and guarantee.
Nothing shady, nothing pirated. Just volume licenses normally reserved for multinationals, available to one person.

05 Open Source
JotDrop
github.com/Diexar-Labs/jotdropNot every project needs to be a business. JotDrop is an open-source experiment from Diexar Labs — built because I needed it myself, then put on GitHub for anyone who finds it useful.
Look at the code. Fork it. Open a PR. Or forget about it entirely — also fine.
View on GitHubWhat others say
No reviews. Just people.
Three lines below, pulled verbatim from emails. No five-star balloons, no star systems — just what people wrote when they didn't know it would end up on a site.
Finally a program that speaks my language. I went from knowing nothing about AI to my first €850 within a month. Wouldn't have believed that 25 years ago.
I needed fifteen standard Office licenses for my team but refused retail price. Five minutes after paying they were in my inbox. Zero hassle.
The depth of Eric's voice gives our product launch exactly the high-end feel we wanted. He sent a custom demo the same day — not a generic reel.
A quick note
A question, a brief, or just feel like a good conversation?
Whether it's about a voice-over, a license, a question about the program, or something else entirely — I read everything myself and usually reply within a working day.
