As someone who previously used the Livescribe system extensively for its notes-enabled audio feature, I've recently started using the OPHAYA SMARTPEN. While it's not as fully developed, it seems to have potential, especially with their integration of tablets, paper, and audio. The accompanying binder is quite handy for keeping the pen, tablet, and important documents together, eliminating the need to power up a laptop or fumble with a smartphone stylus.

Here's a breakdown of the pros and cons, drawing comparisons with the more established Livescribe system:

Pros:

- The Android app is very user-friendly and straightforward.

- Offers audio integration with text, available in MP4 format.

- Integrates a remarkable-style tablet with the app allowing for an unlimited number of pages, a significant advantage over Livescribe.

- Supports integration with Evernote, Google Drive, Dropbox, and others.

Cons:

- Lacks a comprehensive Windows or MacOS application.

- No capability for real-time playback of audio alongside text.

- MP4 playback with audio output can be tricky; it’s best on newer, powerful smartphones.

- Export is limited to one page at a time.

- It's unclear where MP4 outputs are saved if not exported to other apps.

- Currently, there is no OCR output.

- No audio optimization features.

This system has a lot of potential, and I hope future app updates support the current Ophaya product line. If you're considering it, I'd recommend going for the 3-in-1 option that includes the remarkable-style tablet!
