## Description

See how any news article is slanted — right in the article itself.

Click the Slant Detective icon on any news page and a sidebar 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 unless you choose to run in-depth analysis with your own API key — and then it goes straight to your chosen provider.

────────────────────────

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 from your browser straight to your provider. We never see the article or the key.

FIRST-TIME SETUP ON FIREFOX
If the Slant Detective icon isn't visible after install, right-click the toolbar, choose "Customize Toolbar," and drag the icon onto the bar. Click it on any news article to toggle the sidebar.

Note: Firefox's sidebar is global (one instance across all tabs), not per-tab. When you switch tabs, Slant Detective re-runs against the new article automatically.

────────────────────────

COST
Free tier is free forever. In-depth analysis uses your own API key, and you choose the provider: Gemini 2.5 Flash runs about $0.0002 per article — well under $1/month for a typical reader. Claude Haiku runs about $0.0018 per article — roughly $1–3/month. OpenAI GPT-5-mini sits in between. You pay your provider directly — we take no cut.

OPEN SOURCE
Full source, the bias-word lexicon, and the outlet-label dataset are all AGPL-3.0 on GitHub. You can verify exactly what data leaves your device and where it goes. We run no backend. No account database. No advertising.

────────────────────────
