An Open Source Chrome / Brave Extension

What it does

See the emotion behind every tweet

Sentiment eXposed is a free, open-source browser extension that uses the xAI Grok API to analyze the sentiment and emotional tone of tweets as you scroll your X feed. Each tweet is quietly colorized — green for positive, yellow for neutral, red for negative — and tagged with the detected emotion right in the header. Hover any tweet for a full breakdown. It runs entirely in your browser; no data leaves your machine except the tweet text sent to xAI for analysis. This is a quick way to see how different tweets breakdown on your feed, or the distribution of replies for any tweet. See screenshots for more detail.
