NewsLens: Side-by-side bias scorer for live news articles

Problem: Politically aware readers know they are stuck in echo chambers but have no low-friction way to check the lean of an article while they are reading it. Visiting a separate rating site like AllSides breaks the reading flow and requires the reader to manually search for the source. NewsLens is a browser plugin that scores political lean and surfaces missing perspectives on any live news URL in one click. Solution: Rather than making the reader leave the page, NewsLens injects an inline panel that highlights the detected lean of the piece and lists perspectives or framing that are absent, so the reader gets a side-by-side view without switching tabs. MVP: A browser extension that, on click, parses the current article URL and text, returns a lean score, and shows a short list of contrasting sources or omitted angles. Revenue: B2C consumer subscription is the natural path here, a low monthly fee for unlimited scoring plus a free tier limited by number of checks. The comparables (Gumroad, Stan, easytools) show creator and tool sellers pulling meaningful monthly revenue through simple checkout, which supports a direct-to-consumer paid model over ad dependence. GTM: Seed inside the exact communities already arguing about media bias - Hacker News threads on Media Bias Fact Check and the several YouTube channels debating legacy media bias. Growth loops: shareable per-article bias cards that link back to the plugin, plus a browser store listing that compounds through reviews.
