reTerminal Sticky - The AI E-Ink Notepad Your Whole Family Can Use

What would it look like if the sticky notes on your fridge became electronic devices? That's exactly what this product feels like. You stick it to a wall or fridge with a magnet, leave a voice memo, and it shows up on the e-ink screen like handwriting. The photo of several of these mounted side by side is what caught my attention right away.

🔍 Why I'm Interested

The combination of e-ink and voice memos

E-ink displays are known for low power draw and easy readability, and this one adds a microphone that converts your speech into a memo. Being able to leave a note just by speaking, at moments when typing by hand feels inconvenient, seems genuinely practical.

A clear positioning: shared with the family

What's unusual is that this isn't designed as a personal diary but built for "sticking up where the whole family can see it." The photo of separate units for weather, clock, and notes, each mounted in its own spot and readable at a glance, actually looked quite useful.

Open-source firmware support

Apparently several open-source firmware projects — Crosspoint, TRMNL, ESPHome/OpenDisplay, and more — already support this device. That means there's room to customize it into a smart home dashboard, which makes it interesting from an extensibility standpoint too.

🤔 Points I'm Weighing

The limits of the screen size

At 3.97 inches, it's smaller than a smartphone screen, so it can't hold much information at once. You have to keep in mind this is a product designed around using multiple units together.

How well the AI voice feature actually works

How accurately the "AI voice memo" feature recognizes speech in real use is something you can only find out by actually using it, so this is a product where I'd want to dig up more reviews and real-world impressions first.

🛒 Before You Buy

✅ Recommended for

• Anyone who wants to give the shared notepad they use with family or roommates a smart upgrade
• Maker-minded users interested in e-ink and open-source firmware

❌ Not recommended for

• Anyone who needs to view a lot of information on a large screen at once
• Anyone who prefers the feel of plain paper notes

🎯 Final Verdict

The reTerminal Sticky feels less like a "smart display" category product and more like an "electronic sticky note you talk to." The screen is small, but that's precisely what makes it easy to mount several without feeling like a burden, and the voice-memo approach seems to fit naturally into everyday routines.

This is a product that becomes far more appealing once you think of it as something shared with family or roommates, rather than a diary for personal use. The fact that it even supports open-source firmware is a nice bonus in terms of expansion potential.
