NotelyVoice is a cross-platform note-taking application designed for privacy-conscious users, offering on-device AI-powered speech-to-text transcription in over 50 languages. It targets students, professionals, and researchers needing efficient, hands-free note-taking across Android and iOS devices, with the benefit of complete data privacy.

How It Works

The app leverages OpenAI's Whisper AI for robust, offline speech recognition, processing all audio and transcriptions locally on the user's device. It employs memory-efficient audio processing techniques, including a streaming WAV decoder and overlapping chunk transcription, to handle long audio files without memory errors. This approach ensures high accuracy and privacy, as no data leaves the device.
