Free local transcription, captions, and AI voice
Privro AI is a browser suite for free local transcription, Caption Studio, and an AI voice generator. Whisper speech-to-text and on-device text-to-speech run on your hardware, so local tools do not upload your media to Privro.
Local transcription, caption editing, and text-to-speech

From file to export in three steps
Add media, run a local tool, then download a transcript or video.
Add your media
Drop a video or audio file, paste a URL, or record from your microphone. Local tools keep files on your device.
Transcribe, caption, or speak
Run Whisper transcription, style captions, or generate a voiceover. Processing for these local tools happens in your browser.
Export what you need
Download transcripts as TXT, JSON, CSV, SRT, VTT, XLSX, DOCX, PDF, or export captioned video up to 4K for YouTube, TikTok, Instagram, Reddit, X, or LinkedIn.
Your media stays on your device
Cloud editors often require an upload and an account. Privro's local tools process files in the browser instead.
Typical cloud tools
- Upload media to third-party servers
- Files may be stored or used under the vendor's terms
- Account required before you can start
- Quotas, credits, or monthly plans
Privro local tools
- No upload to Privro for local transcription, captions, or voice
- Private and rights-sensitive media stay on your device
- No account for local use
- Unlimited local use with no hidden usage fees
Built for local-first creators
Free browser tools when you need transcripts, captions, or voiceovers without giving up control of your files.
Free for local use
Local transcription, captions, and voice tools cost nothing. No subscription for on-device processing.
No account needed
Open the tool and start. Local features do not require a sign-up.
Files stay on your device
Local tools do not upload your media to Privro, so private or rights-sensitive files stay under your control.
Works in the browser
Use Privro on desktop, tablet, or phone. No desktop install for the core tools.
4K caption export
Export captioned video up to 4K for YouTube, TikTok, Instagram, Reddit, X, and LinkedIn.
Whisper on your hardware
Speech-to-text runs with Whisper in the browser, so accuracy depends on your device, not a shared cloud queue.
Common questions
Short answers about free local transcription, captions, and AI voice.
Is Privro AI free?
Yes. Local transcription, Caption Studio, and the AI voice generator are free for local use. You can run them without a subscription or usage quota for on-device processing.
Do my videos or audio files get uploaded?
No. For local tools, Privro processes media in your browser on your device. Your files are not uploaded to Privro servers for those local workflows.
Can I use private or copyrighted media?
Local processing keeps your files on your device, which helps when you need to keep private or rights-sensitive media off third-party servers. You still need the rights to use the content. Privro does not grant copyright permission.
Does Privro work offline?
After the page and models load, local transcription and related tools can run without sending your media to the cloud. You need a network connection for the first load and for any non-local features.
What can I export?
Transcription exports include TXT, JSON, CSV, SRT, VTT, XLSX, DOCX, PDF. Caption Studio exports styled video up to 4K for YouTube, TikTok, Instagram, Reddit, X, and LinkedIn.
How does the free local AI voice generator work?
The voice tool at voice.privro.com turns text into speech with on-device text-to-speech. You do not need an API key for local voice generation.
