Privoxa -文字起こし・翻訳・録音

Privoxa is an offline app that transcribes recorded audio directly on your device. It's useful for situations where you want to record your voice in text, such as meetings, interviews, lectures, or taking notes.

Transcription is performed in the background, allowing you to work on other tasks while transcription is in progress.

【Privoxa Features】

■ Fully Offline
A transcription model download is required only the first time you use it. After completion, internet connection is not required for the transcription process itself. It can be used reliably even in areas with poor signal reception.

■ Privacy-Focused
Recorded audio is processed within your device. It does not send audio data to an external server for transcription. Ideal for those who want to handle important conversations and work content solely within their device.

■ Simple Operation
Simply open the app and start recording. After stopping, the audio is automatically transcribed, and you can review and edit the results. Real-time display (Premium) allows you to check the text while speaking.
