Every review below is a real 5-star experience.
SecondBrain Note has completely transformed how I handle client meetings. I used to scramble to write everything down — now I just wear it and the transcript is waiting for me before I'm even back at my desk.
Literally changed my process of attending meetings, I can be fully present knowing I will have perfect notes afterwards.
Most amazing thing ever! We just held a six-day conference, and it was able to capture everyone's presentation in such fine detail. You guys are some cool cats and kittens.
Great product !!! Highly recommend. The quality exceeded my expectations, and it works exactly as described. From unboxing to daily use, everything has been smooth and reliable. If you're on the fence, don't hesitate — you won't regret this purchase.
Hello, This product is truly outstanding, and I was honestly amazed. It accurately recognizes and captures spoken content, and turns it into a well‑organized report or meeting minutes with exceptional quality. I was also impressed by how compact it is and how little space it takes. Until now, I had been using other recording devices from SOURCENEXT and「 AutoMemo」, which also have good transcription accuracy. However, this product is overwhelmingly superior in overall quality. I look forward to continuing to use it. Thank you very much.
amazing device for keeping track of life’s important conversations. It gives you the freedom to engage when you need to and turn it off when you don’t. Its excellent microphones can distinguish words and speakers even in less-than-ideal settings, including busy streets, dog parks, and crowded restaurants. The transcription in Genspark is solid, with critical points clearly extracted. Its built-in intelligence helps identify the key information while filtering out the rest. My only caution is that it can be difficult to tell when the device is recording. Highly recommended overall.
