Privro AI is a free browser suite for local transcription, Caption Studio, and AI voice. Whisper and TTS run on your device with no upload for local tools.
When I used to search for free transcription there were only paid tools, when you upload your file they just ask you to signup and pay the subscription fee. Then after researching a bit i found you can run whisper locally on your device for free, and around the same concept I have built privro for local transcription it's truly unlimited free with no signup required.
