Bullseye

Instantly fact-check selected text with confidence scoring and source analysis

Bullseye puts a mini fact-checker in your browser Just highlight text and hit ⚡ Check fact. After a few seconds you'll see: • Confidence score 0-100 – how strongly the web supports or contradicts the claim, based on source count, quality, consensus & recency. • Supporting vs. contradicting sources are shown with titles, excerpts, and live links. Why you might like it • I wanted to stop hopping through ten tabs just to verify one statement. • I wanted a score that sums up multiple quality signals. • I wanted only the handful of links that really matter. How it works in simple terms • Only the text you select is sent (securely) to my API. • It returns a plain JSON answer; the extension shows it in the panel. • Nothing about you is saved on my server, results stay in your browser’s local storage. Permissions kept to a minimum • “ActiveTab” to inject the button. • “Storage” to keep the last result if you close the panel accidentally. • A single host permission for my own API endpoint. Roadmap • Image OCR fact-checking • Exportable fact-check reports • Optional crowd-sourced “Is this helpful?” voting This is just a solo student project if there are bugs or just Ideas?
