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
Seven 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
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.
No smoke. If I wouldn't recommend a tool or course to my best friend, it doesn't ship. Sounds obvious. Isn't.
Simplicity isn't a "feature". It's the whole job. Once someone in their 70s gets it, I'm done.
Clear prices, honest promises, products you can just open and use. Beyond that, I shut up.
The work
One program, two pieces of software, one voice, one open-source experiment — and two new learning platforms in the making. All under the same roof.
The 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.
See the programTwelve 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.
See the toolkitDeep, 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.
Listen to a demoReal 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.
See the licensesNot every project needs to be a business. JotDrop is an open-source experiment from diexar.com — 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 GitHubA calm learning platform where people 50+ learn, step by step, to make their own digital products with AI. No tricks, no jargon — just the skill, at your own pace.
The site is ready. It goes live the moment the last paperwork is done; then you can simply walk in and start.
Launching soonA practical video course that helps small and medium businesses actually use AI in their daily work. Showing instead of explaining: each video delivers one concrete result you can apply the same day.
Two tracks, for beginners and the more advanced. Privacy-first throughout — your customer data should stay yours.
Launching soonWhat others say
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
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.
