SourceTrace

Trace the sources on any page

Free · Designed for iPad. Not verified for macOS.

Photograph any page and see the evidence behind its claims. SourceTrace finds the factual statements, then searches the web for real sources - never invented ones. Photograph a page. See what's behind it. SourceTrace takes a photo of any page — a book, a magazine, a newspaper, a printed article — pulls out the factual claims on it, and goes looking for the sources behind them. HOW IT WORKS Photograph the page, or pick a photo from your library. SourceTrace reads it and lists the factual claims it makes. For each claim, it searches the web and shows you what it found, with real links you can open and read. Each claim comes back marked with what the evidence looks like: well supported, mixed, contradicted, or nothing found. You also see whether the author cited anything on the page itself, which is often the more interesting answer. WHAT IT WON'T DO SourceTrace never invents a source. Every link it shows came back from a live web search - no generated citations, no plausible-looking references to books that don't exist. It also doesn't tell you what's true. A claim marked "well supported" means the search found sources that agree with it, not that a verdict has been reached. You get the evidence and the links; the judgment stays yours. BUILT FOR • Readers who want to check a striking statistic before repeating it • Students and researchers tracing a claim back to its origin • Anyone reading nonfiction who has wondered "where did that come from?" PRIVACY Your page is uploaded so it can be read and searched, and it isn't stored on our servers. Your history stays on your device. No account required, no advertising, no tracking. Try the built-in example before you photograph anything - one tap shows a full analysis of a real passage.

Better answers, and an honest one where there was a misleading one. • Sources you were meant to find. The app now searches using the whole page for context rather than the claim sentence alone, so a name that means little by itself - a common surname, a type of business, a location - is matched against what the page is actually about rather than whoever else shares the name. Measured on our own test set, it finds a known-good source for roughly two claims in three, up from about half. • A higher bar before a book is called wrong. Marking a claim Contradicted now takes two independent sources rather than one, so a single loosely-related page can no longer put a question mark over something you are reading. • No claim quietly disappears. A claim the app struggled to search for used to vanish from the results without a trace. It stays, and tells you what happened. • "Author's own reporting." Some claims rest on an interview the author did, or something they witnessed - the book is the source, and no search will find one. Where we can tell, those now say so rather than reading as a failed search.
