WhatsApp Voice Transcriber

Manually transcribe WhatsApp Web voice messages with your own OpenAI API key.

Tired of long voice messages you can't listen to right now? WhatsApp Voice Transcriber adds two buttons to every voice note on WhatsApp Web: Transcribe — converts speech to text using OpenAI's latest transcription models. Get to the point! — gives you a 1-3 sentence summary so you can skip the rambling and get straight to the message. No playback required. Just click and read. HOW IT WORKS 1. Install the extension and add your OpenAI API key in the settings page. 2. Open WhatsApp Web (web.whatsapp.com). 3. Every voice message gets a "Transcribe" and "Get to the point!" button. 4. Click either button. The extension decrypts and sends the audio to OpenAI, then shows you the text right below the voice note. PRIVACY FIRST - Audio is sent to OpenAI only when YOU click a button. Nothing is auto-transcribed. - Your API key stays in the extension — it is never injected into the WhatsApp Web page. - No custom backend. No data collection. No analytics. The extension talks directly to OpenAI's API from your browser. - Transcripts are cached locally so the same voice note is never billed twice. FEATURES - One-click transcription powered by OpenAI's gpt-4o-mini-transcribe (or choose whisper-1, gpt-4o-transcribe, or gpt-4o-transcribe-diarize) - "Get to the point!" instant summaries via GPT-4o-mini - Works without playing the voice note first - Local transcript caching to avoid duplicate charges - Copy button for easy pasting - Language hint option for multilingual conversations - Clean, minimal UI that fits naturally into WhatsApp's design - Supports WhatsApp Web light and dark themes REQUIREMENTS - A free or paid OpenAI API key (get one at platform.openai.com) - WhatsApp Web (web.whatsapp.com) in Chrome COST The extension itself is free. You pay OpenAI directly for API usage through your own key. Typical cost per voice note is under $0.01 depending on length and model. This extension is independent software and is not affiliated with or endorsed by WhatsApp, Meta, or OpenAI.
