Usage recommendations

For best results, position Notra within the 10 m pickup range and avoid placing it too close to strong noise sources. Use Bluetooth mode for private earbud conversations and phone mode when attached to the back of a handset. Select the recorded language in the app before transcription for improved accuracy, and enable cloud backup to preserve recordings. When capturing multi-speaker meetings, use the one-press highlight to tag key moments for faster review.
