Pen Plotters for Professional Artists & Creative Coders

Great Product!

The iAuto handwriting machine is a genuinely impressive device. Build quality is solid — it feels durable right out of the box, and the learning curve is surprisingly gentle even for first-time users. There's something oddly satisfying about watching it work; the mechanical motion holds attention in a way that a printer never could. For outbound sales mail and handwritten thank-you notes, it delivers exactly what you'd want: a personal, human touch at scale without the wrist fatigue. It took me about 30 minutes to get unboxed and set up.

Sturdy machine

I bought the iAuto for business purposes. The goal: Write custom messages on hundreds of postcards to make them feel more personal. I was unsure if this machine would be sufficient, given the comments about the rather outdated-looking software.
When the machine arrived here in the Netherlands, I could get it to run within less than five minutes. Something unimaginable for B2B machinery nowadays. This doesn't mean it lacks customization, though. I managed to create and set up an additional font and custom page sizes even without a tutorial.
When it came to customizing 300 cards, I watched a YouTube tutorial and had everything running within 15 minutes. This machine only slipped up once during the seven hours it took to write 300 detailed A6 postcards! This is quite impressive.
While the software does need some getting used to, it is by no means outdated or unusable.

The support replied quickly during the delivery process and was always eager to help if anything was needed.

I would definitely recommend the iAuto to anyone who needs this for semi-professional or incidental use.

Reliable, easy to use, and worth every penny. Highly recommended!

Mid-sized company | D2C | customer communication

We run a mid-sized company in the D2C space and bought the Uunatek iAuto Handwriting Robot primarily to test whether handwritten customer communication could move the needle for us.

Short answer: it did.

What we like (Pros)

The biggest impact for us was customer loyalty. Handwritten notes simply feel different. They cut through the noise of emails and automated flows. We used the robot for targeted follow-up letters, especially review requests — and saw about a 20% increase in review submissions compared to our previous process. Pro Tipp: If you use a stamp instead of a printed code the likelihood of the customer to open the letter is increased!

It made our brand feel more human and intentional, even though the process is automated behind the scenes.
The machine itself feels solid and well-built. It doesn’t feel like a gimmicky desktop gadget. It runs reliably and gives a professional output.
You're not locked into proprietary pens. We tested different fineliners, ballpoints, and even slightly thicker markers depending on the paper stock. That flexibility makes a big difference if you care about brand aesthetics.
There’s a CURL API interface. It’s definitely more for professionals, but it’s not impossible to work with. If you’re comfortable with basic API integrations, you can automate things quite deeply (e.g., connecting it to order triggers or CRM exports).
For us, that’s where the real power lies.

What could be better (Cons)

1. The GUI software feels outdated
The main downside: the graphical software feels a bit old-school. It works, but the UX/UI could definitely use a refresh. It’s functional, not beautiful.
If you’re expecting a super modern SaaS-style interface, you might be slightly disappointed.

Final Thoughts:
If you're just looking for a novelty device, this might be overkill.
But if you're running a business and thinking seriously about offline customer touchpoints in a digital world, this thing is extremely interesting.
For us, it paid off — especially in review generation and perceived brand value.

Happy to answer questions if anyone is considering it.

Smooth & easy, even in large scale

Setting up and installing was very straightforward. Was working with A3 plotters from before, but the change in scale makes an order of magnitude in differences. Very precise, easy to setup drawing material with the inkscape extension. If you have available space (had to reconfigure my whole studio due its size) I can highly recommend this drawing machine.
