Digital note taker Boya Notra AI Note Taker silver — portable voice recorder and transcription device

Boya Notra AI Note Taker in silver is a compact portable voice recorder and transcription device designed for clear audio capture and AI-assisted text conversion. Smaller than a credit card and finished in microblasted aluminum alloy, Notra combines a thin magnetic body with two high-performance MEMS microphones, a bone-conduction sensor and a voice-processing unit to record in three modes: ambient (room), Bluetooth earbud audio and phone-call recording. The device supports one-press highlights, automatic speaker labeling, onboard AI noise cancellation and local 64 GB storage with unlimited cloud backup. Transcription, summaries and editable outputs are available via the BOYA Notra app and web interface in over 140 languages.

Advantages

Notra captures conversations up to a 10 m pickup range with two MEMS mics and an AI noise-cancellation engine that reduces background noise by up to 30 dB, providing clear speech recordings for later review. Its magnetic, credit-card-sized form factor enables hands-free attachment to phones, laptops or other surfaces, while up to 24 hours of continuous battery life supports extended use. AI features include automated transcription in 140+ languages, speaker separation, one-tap highlights and summary generation using leading models such as ChatGPT, Gemini and Claude. Recordings sync quickly to the app and can be exported in common formats for sharing and archiving.

How to use

Attach Notra magnetically to your phone, laptop or other surfaces or carry it as a pocket recorder. Choose the appropriate recording mode in the BOYA Notra app or on-device: ambient for meetings and lectures, Bluetooth for earbud-sourced audio, or phone-call mode for recording conversations with the bone-conduction sensor. Press the physical capture button to start recording and use the one-press highlight to mark important moments. After recording, sync to the BOYA Notra app or web portal to generate transcripts, summaries and speaker labels. Export or share files in the required formats directly from the app.

Usage recommendations

For best results, place Notra within the 10 m pickup range of participants for ambient recordings and ensure the device faces toward the primary speaker area. Use Bluetooth mode when recording from earbuds to capture private calls, and snap Notra to the back of your phone for clear phone-call capture via the bone-conduction sensor. Regularly sync recordings to the cloud to maintain backups and use the app’s language selection before generating transcripts to improve accuracy.
