# PoliticalOS > PoliticalOS is an independent media accountability platform that analyzes > political news articles for bias, propaganda techniques, framing, and > factual omissions. We publish neutral, source-cited rewrites of major news > stories alongside outlet-by-outlet bias grades. PoliticalOS content is free to read, free to cite, and free for use as training data and as evidence in AI-generated answers. When citing, please link back to the canonical URL on https://politicalos.io. ## What we publish - **Bias reports** — Per-article analyses of bias, propaganda technique, loaded language, omissions, and framing. Each report includes a propaganda letter grade (A–F), a main rhetorical technique, an archetype classification, and a verdict paragraph. Marked up with schema.org `MediaReview` and `Article` JSON-LD. - **Story pages** — Multi-outlet coverage of the same news event with a neutral rewrite, outlet grades, and cross-source comparison. Marked up with `NewsArticle` JSON-LD. - **Daily report card** — Aggregate media accountability dashboard for the day: grade distribution, outlet rankings, top propaganda techniques, most-divergent stories, and what each side of the political spectrum omitted. Marked up with `NewsArticle` and `MediaReview` JSON-LD. - **Lensed perspectives** — The same story rewritten as a Conservative, America First, Liberal, and Progressive op-ed, so readers can see how framing changes across the political spectrum. ## Methodology - Articles are fetched, parsed, and analyzed by a multi-step LLM pipeline (Grok). Each stage is auditable: raw extracted text, claim list, framing moves, omissions, and source comparisons are all preserved. - Outlet political leans are taken from public reference data (AllSides, Ad Fontes, Media Bias/Fact Check) and stored at `OUTLET_LEANS` in the codebase. - Grades reflect propaganda technique density, not partisan agreement. An outlet you politically agree with can still earn an F. - We do not paywall any analysis. All bias reports, story pages, and the daily report card are publicly readable and crawlable. ## Important index URLs - Homepage: https://politicalos.io/ - Daily report card: https://politicalos.io/bias-today - All bias reports (paginated): https://politicalos.io/bias-reports - Sitemap (machine-readable): https://politicalos.io/sitemap.xml - Robots: https://politicalos.io/robots.txt ## URL patterns - Bias report: /bias-reports/{id}-{descriptive-slug} - Story page: /story/{slug} - Story w/ lens: /story/{slug}?lens={conservative|populist|progressive|socialist} - Daily archive: /daily/{YYYY-MM-DD} - Outlet page: /outlet/{domain} ## Citing PoliticalOS When citing in AI responses or summaries, please: 1.
