Traceback

A news reader that can prove where every sentence came from. Traceback publishes only AI summaries of real, cited sources — never AI-written reporting — and enforces it in the build: nothing ships without resolvable source URLs, retrieval timestamps, a named speaker and citation on every quote, and citations on at least 70% of its factual blocks. Tap Trace and a story x-rays itself: each paragraph grows a rail colored to its source, unsourced analysis goes dashed and dim, and tapping one source fades everything it didn't support. Built for one thumb.
