Detect biased, clickbait or untrustworthy news — in-page analysis tool

People who read news regularly, especially the estimated 200 million global users willing to pay for better news experiences, face growing difficulty distinguishing biased, clickbait or untrustworthy articles from legitimate reporting; this costs time, corrodes trust and leads to poor personal and civic decisions. Institutions—libraries, schools, publishers and brands—share the problem because they must defend reputation and ensure audiences see credible information. A practical product is an in-page analysis tool delivered as a browser extension and embeddable widget that scores articles on bias, factualness and clickbait risk, surfaces sentence-level highlights and provenance links, and shows a calibrated confidence score plus short explainability notes. The core offering can be complemented by a publisher-facing API and enterprise dashboard for monitoring, licensing, and whitelisting, with subscription and licensing revenue paths. Timing is favorable: the total addressable market is roughly $8.4B (200M paying users x $42 ARPU/year), public concern about misinformation is rising, and AI/NLP tooling now makes reliable classification and transparent explanations economically viable. Browser extensions remain an efficient distribution channel, lowering CAC and enabling rapid user feedback loops. To stand out you must focus on measurable trust signals and explainability rather than opaque scores—linking claims to sources, offering human-in-the-loop verification for edge cases, and providing local client-side options for privacy-conscious users. Challenges are real: classifiers make errors, there is regulatory and reputational risk, and competition is medium; success will depend on conservative accuracy thresholds, clear UX about limitations, and strategic partnerships with fact-checkers and publishers rather than trying to be the sole arbiter of truth.
