WhatsApp Audio Transcription Chrome Extension Using GROQ API

A Chrome extension that adds transcription buttons to WhatsApp Web audio messages using the GROQ API.

Why Groq?

• Fast, basically free with their free tier, and the Whisper (turbo) model is really good.

How It Works

• After each audio message in WhatsApp Web, a "Transcribe" button appears. Click it to instantly transcribe the audio and display the text directly below the message.
• Transcriptions are stored in localStorage for up to the latest 3 days, allowing reuse without additional API calls.
• The Whisper model outperforms Meta's native transcriber, delivering outstanding transcription quality.

⚠️ Important Notice

This extension is not officially associated with WhatsApp or Meta. Please be aware that:

• Using unofficial modifications to WhatsApp Web may violate WhatsApp's Terms of Service
• Audio data from messages is sent to GROQ's API for transcription
• Its recommended only using this extension for personal, non-sensitive communications

Installation

1. Clone or download this repository
2. Open Chrome and navigate to chrome://extensions/
3. Enable "Developer mode" in the top right corner (if needed)
4. Click "Load unpacked" and select the directory containing these files

Technical Details

The extension works by:

1. Injecting custom UI elements into WhatsApp Web
2. Using WhatsApp's internal APIs to access audio data (thanks to pedroslopez/whatsapp-web.js)
3. Converting audio to the required format
4. Sending to GROQ's Whisper API for transcription
5. Displaying results in the WhatsApp interface

Troubleshooting

Q: Im getting an error (Error - Try again)

• R: Ensure you setup the API Key correctly. Open Extension Settings and add your own Groq API Key, select the model and save.

TODO

• Add more providers (openai, openroute, ollama, etc...)
