W Log

W Log is a Chrome extension that turns a spoken workout description into a clean, formatted workout log. You click Speak, describe what you did, and the extension uses a language model to rewrite it as one line per exercise with weights in both kilograms and pounds.

W Log was built as a hackathon project. It is a prototype rather than a finished product.

Features

• Voice input using the browser's Web Speech API (en-US), with a live transcript shown while you talk

• Workout formatting by sending the transcript to openai/gpt-4.1 through the GitHub Models chat completions API, producing lines like:

  Calf Raises - 2x16 (20 kg / 44 lbs)
  Pogo Hops - 3x20 (Bodyweight) (90 sec rest)
  

• Copy the formatted log to the clipboard

• Save the log as a text file named workout_YYYY-MM-DD.txt

The Save to Docs button is a placeholder and is not implemented yet. popup.html also contains a text box and a Submit Workout button for typed input, but they are hidden and not connected to any code.

Tech stack

• Chrome Extension (Manifest V3)
• HTML, CSS, and vanilla JavaScript
• Web Speech API for speech recognition
• GitHub Models API (https://models.github.ai/inference/chat/completions)

There are no dependencies and no build step.

Getting started

1. Clone the repository:

   git clone https://github.com/SummerPandey/Google-Hackathon.git

2. Add an API token. popup.js sends this.apiKey as a bearer token, but the value is not set in the repository. Create a GitHub personal access token with access to GitHub Models, then set it in the VoiceAssistant constructor in popup.js:

   this.apiKey = 'your-github-token';

   Do not commit the token. Anything in an extension's source can be read by whoever installs it, so this setup is only suitable for local use.

3. Open chrome://extensions, turn on Developer mode, click Load unpacked, and select the repository folder.

4. Click the W Log icon in the toolbar, press Speak, and allow microphone access when prompted.
