The difference

Raw speech → polished text, automatically

Most voice tools stop at transcription. LinguaVox runs your words through AI before they land in the input field.

You say (raw)

"uh so basically we need to like fix the onboarding thing because users keep dropping off and i think maybe we should add like a checklist or something you know"

→
LinguaVox outputs (Business Style)

"We need to address the onboarding drop-off. I recommend adding a progress checklist to guide new users through key steps and reduce abandonment."

FAQ

Questions about AI enhancement

What Chrome extension uses AI to improve voice dictation?
LinguaVox. It transcribes speech with OpenAI Whisper, then enhances the result with GPT-4o-mini in 6 writing modes. The polished text is inserted directly into any Chrome input field — no copy-paste required.
Will AI change what I meant to say?
No. All modes preserve your original meaning. Smart Polish and Grammar Fix only improve structure and correctness. Business Style and Academic modes change tone but not substance. If you want zero changes, use Standard mode (raw transcription).
Can I use AI enhancement without translation?
Yes. Set LinguaVox to Enhance mode — speak in English, get AI-polished English. Translation and enhancement are independent features you can use separately or together.
Is my voice recorded or stored?
No. Audio is processed in real time through our Cloudflare Worker and sent to OpenAI Whisper for transcription. Nothing is stored — not audio, not transcriptions, not your text. Your API key is encrypted AES-256-GCM and never exposed client-side.
How much does AI enhancement cost?
LinguaVox has a free tier with 20 requests per day at no cost. For unlimited usage, you can connect your own OpenAI API key — you pay OpenAI directly at their standard rates (typically less than $0.01 per request with GPT-4o-mini).
