The Juno pen is a voice recorder and a real ballpoint pen. It has a 360° microphone, 72 GB of storage and about 35 hours of recording per charge.
In the box: the pen, a USB-C to USB-A cable, earphones, spare ink refills and a small screwdriver.
Open it and charge it
Open the pen at the ring. The USB-C plug is right there. Plug it into a laptop, phone, tablet or charger.
Press once to record
Press once to start. Voice mode pauses in the silences, so long meetings stay short to review.
Plug it in to get your files
Plug the pen into your computer or phone. It shows up like a USB drive. Each recording is a file named by when it started, for example R20260922-213209.WAV.
If the battery runs low, the pen saves the recording before it powers down. You don’t lose the take.
Long recordings
The pen splits long recordings into several files. When you upload them, Juno joins files whose times line up into one meeting. If it isn’t sure, it shows a Join into one meeting banner. See Combine and split.
The pen’s clock
Juno uses the time on each file to date your recordings and to join the parts of a long one. If your pen’s clock is wrong, fix it in the pen settings file.
