NEWYES's SyncPen series has continued to evolve as a smart pen that instantly digitizes handwritten text and drawings created the analog way. The fourth-generation model in this lineup is the SyncPen 4.
This is more than just a "pen" — it's a tool that smooths out the entire write → save → reuse experience. Whether for work or study, the very "act" of taking notes is transformed.

The NEWYES SyncPen 4 is a next-generation smart pen that digitizes handwritten text and drawings so you can manage them on your smartphone or PC. You can sync in real time to a dedicated app via Bluetooth, and even when offline, it can temporarily store data in the pen's internal memory.
What you write can be converted to text using OCR (optical character recognition), then shared as a PDF or image — allowing you to seamlessly write → save → share, all in one flow.

Compared to the previous generation (SyncPen 3), the SyncPen 4 brings several improvements:
① Erasable ink & reusable notebook
The SyncPen 4 uses erasable ink. By wiping with a damp cloth or applying heat, you can reuse the notebook again and again. This is an evolution that lowers paper running costs while enabling eco-friendly use. Some reviews of the SyncPen 3 noted that its ink couldn't be erased or that its erasure functionality was weak — making this a major leap forward.
② USB Type-C charging
The SyncPen 4 features a USB Type-C port, boosting charging versatility. Since the SyncPen 3 used the older microUSB, cable compatibility and convenience have improved significantly.
③ Offline storage & Bluetooth 5.0
The SyncPen 4 supports Bluetooth 5.0 for a stable connection, and it also has an offline mode that stores notes inside the pen itself, so you can record with peace of mind even in places without network access.
④ Notebook material with high reuse count
The special-material notebook is rated to withstand over 500 cycles of writing and erasing, allowing you to use it in a way that brings disposable paper notebooks close to zero.

The SyncPen 4 doesn't just "digitize" — it does much more:
Real-time syncing – Connect to the smartphone app and what you write is instantly turned into data.
OCR text recognition – Converts handwriting into editable text.
Offline storage – Even without the app, you can transfer everything later in one go.
Data sharing – Save as PDF or image, and send via social media or email.
With this, the flow of "write → what to do with it" for meeting notes, class notes, and idea sketches is dramatically transformed.
| Comparison with previous models (differences from SyncPen 3)
| Item | SyncPen 3 | SyncPen 4 |
|---|---|---|
| Charging port | microUSB | USB-C |
| Ink erasure | Not possible | Erasable with damp cloth or heat |
| Notebook reuse | Standard paper | Reusable material rated 500+ cycles |
| Connectivity | Bluetooth (older) | Bluetooth 5.0 |
| Offline storage | No in-pen memory / weak point | Records via built-in memory |
In this way, the SyncPen 4 has dramatically advanced the everyday "write → erase → digitize" flow.

Want to keep digital records of handwritten meeting and class notes Don't want to constantly switch back and forth between writing and going digital Want to reduce the waste and cost of paper notebooks Want to record and share immediately, even on the go Want to turn handwritten thoughts directly into "searchable data"
For people with these needs, the SyncPen 4 stands as a "smart tool that keeps the act of writing uninterrupted."
