Slant Detective

See how any news article is slanted — the lean, the loaded words, the phrases doing the work. In the article itself.

Click the toolbar icon on any news page and a side panel opens with a structured readout: the overall lean, the loaded words, and the specific phrases doing the persuading. Every flagged phrase is underlined in the article so you can see the evidence in context. No account. No server. Your article never leaves your browser. ──────────────────────── FREE — instant, no setup, no key required An entirely in-browser analysis: • A 2,100-word bias lexicon from peer-reviewed research (BABE) • Attribution-verb skew ("said" vs. "alleged" vs. "admitted") • Headline-vs-body drift • Hedge-word count • An outlet-level lean label (e.g. "Lean Left," "Center") IN-DEPTH ANALYSIS — paste your own API key Paste a key from Anthropic, OpenAI, or Google and unlock: • An overall intensity score and direction • A four-dimension breakdown (word choice, framing, headline, source mix) • Evidence phrases with a one-sentence reason for each • Dotted underlines on the actual biased phrases in the article • Hover for the reason, click to scroll to the phrase Your key stays in your browser. The call goes straight from your browser to your provider. We never see the article or the key. ──────────────────────── COST Free tier is free forever.
