Online articles are full of unverified claims, missing context, and jargon that goes unexplained. Readers have to fact-check things themselves, open a dozen tabs, and still walk away unsure what's true. DOMinion is a Chrome extension that brings something like Community Notes to every article you read, except it's instant and powered by AI research instead of waiting for crowdsourced votes. Click the extension, and it scans the article and annotates it with four types of highlights: - **Fact Check**: verifies claims against other sources the agent finds through deep research - **Missing Context**: surfaces important background or framing the article left out - **Explanation**: breaks down jargon, technical language, or complex concepts - **Source Analysis**: follows the article's cited sources and evaluates whether they actually support the claims being made Each annotation pulls from both the article itself and from other articles the agent researches in real time. Hover any highlight to see a summary. Click it to start a conversation and dig deeper. It works on news, opinion pieces, and arXiv papers. **Built with:** Gemini LLMs (3.1 Flash Lite for speed or Pro for thoroughness depending on the article's complexity), Google Search grounding, Chrome Extensions API.
