SourceSift

SourceSift is a web + mobile app where communities collaboratively verify online claims by attaching primary sources, context, and credibility notes to specific sentences in articles, posts, and videos. Users submit a claim snippet and a link; others add citations (papers, official docs, datasets), flag misleading framing, and vote on the best evidence. A lightweight reputation system rewards accurate sourcing and penalizes low-quality drive-by opinions. The product focuses on “micro-curation”: small, checkable units instead of endless comment threads. Creators and moderators get shareable “evidence cards” that summarize the strongest sources and the main counterpoints, plus an embed widget for newsletters and blogs. It’s not a full fact-checking newsroom; it’s a structured, community-generated evidence layer that makes verification faster and less chaotic than social media replies.
