Show HN: Biasly.ai – Bias detection with historical context

Biasly.ai, a free AI media bias analysis tool, detects manipulation techniques in news articles and videos sentence by sentence, and provides historical context for stories on geopolitics, economic and health policy, immigration, and civil rights, with every claim cited to Wikipedia. The tool uses a fine-tuned transformer to classify sentences and Claude AI to explain flagged techniques, and it analyzes up to 500 paragraphs per article or video transcripts in 1-minute segments.

See how → historical-context How Biasly works Biasly analyzes news articles, videos, and text for media bias and manipulation techniques — loaded language, false equivalence, historical revisionism, geopolitical framing, and more. Unlike a traditional fact-checker, it identifies how language is used to manipulate, not just whether specific claims are true. Article, text, or video Paste a URL, drop raw text, or paste a video link — YouTube, TikTok, Instagram, Facebook, or X. For articles we follow pagination automatically and analyze up to 500 paragraphs. For videos we analyze the transcript in 1-minute segments. Two-stage AI analysis A fine-tuned transformer classifies each sentence as manipulative or neutral. For flagged sentences, Claude AI identifies the specific technique and explains why it's manipulative — no generic labels, just precise analysis. See exactly what's flagged — plus who's being quoted Flagged sentences are highlighted in red. Hover or tap any paragraph to see which technique was used and a plain-English explanation. A separate source distribution panel shows who's being quoted in the article — by role and national affiliation — and flags imbalances. See the history this article leaves out When an article has a real backstory — a geopolitical conflict, a financial crisis, a decades-long policy fight, a public-health debate, a civil-rights movement — Biasly surfaces the historical background most coverage skips. Two tabs side by side: a neutral encyclopedic overview, and a "what this article doesn't tell you" view that pinpoints what's missing relative to what the article addresses. Routine business, sports, and celebrity stories return nothing — no scope creep. US–Iran relations have been shaped by the 1953 CIA- and MI6-backed coup against Prime Minister Mohammad Mossadegh after his nationalization of Iran's oil industry, the 1979 Islamic Revolution and ensuing hostage crisis, the Iran–Iraq War of the 1980s during which the US backed Iraq , the 2015 Joint Comprehensive Plan of Action nuclear deal, and the 2018 US withdrawal followed by escalating sanctions. Wikipedia-cited. Every factual claim links to a Wikipedia article — and the URL is HEAD-validated before it reaches you. No hallucinated links. Delta mode. The "omitted" tab compares what the article addresses against what's commonly skipped, so you see the specific gap — not a generic history dump. Streams in under 5 seconds. Topic and sources appear right away; prose fills in progressively. Cached for 30 days — the same article re-opens instantly. 18 manipulation techniques, automatically identified Manipulation rarely announces itself. These are the patterns our AI is trained to catch — and explain. Loaded Language Emotionally charged words that trigger fear, anger, or contempt rather than informing. Name Calling / Ad Hominem Attacking a person or group with derogatory labels to discredit them without engaging their argument. Appeal to Fear Exaggerating threats to override rational analysis and demand immediate action. Bandwagon Appeal Pressuring agreement by claiming everyone is already on board, suppressing independent thought. False Urgency Manufactured time pressure that discourages careful analysis and demands immediate compliance. Black-and-White Fallacy Presenting only two extreme options when a range of alternatives actually exists. Historical Revisionism Rewriting, minimizing, or denying documented historical events — colonial atrocities, genocides, war crimes — to serve a current narrative. War Crime Euphemisms Sanitized language that obscures documented violations of international law. False Equivalence / Whataboutism Creating artificial moral balance between actions that aren't comparable — including deflecting criticism by pointing to opponents' wrongdoing "bothsidesism" . Geopolitical Framing Describing a conflict using one side's preferred framing as if it were neutral fact. Appeal to Prejudice Exploiting existing biases against an ethnic, religious, or social group to build support. Conspiracy Appeal Attributing events to secret powerful forces to explain away inconvenient facts. Exaggeration / Hyperbole Dramatic overstatement that distorts scale and severity to heighten emotional impact. Victim Blaming Language that shifts moral responsibility onto the victims of violence or oppression. Scapegoating Blaming a specific group for complex social, economic, or political problems they didn't cause. Card Stacking Selectively presenting evidence that supports one conclusion while omitting information that would complicate it. Glittering Generalities Vague, emotionally positive words — freedom, liberty, heritage, values — used as rhetorical flourish without specific meaning. Repetition Deliberately repeating charged words or phrases to make a claim feel more established than it is. See it in action Biasly catches manipulation across the political spectrum — international conflicts, domestic politics, left-leaning and right-leaning media alike. Three of the five paragraphs use loaded language, geopolitical framing, or appeal-to-fear patterns.
