In 2021, a WhatsApp message told 3 million people that vaccines contained a microchip — before any fact-check could reach them. It came too late. The belief was already alive. BiasCheck is about reversing that.

BiasCheck analyses any news article or claim in the present. First, paste a headline or search a topic and within seconds you see:

• where it sits on the political spectrum,
• how a news outlet frames the story across persuasion and evidence,
• any emotional language signals detected
• what claims it makes,
• and a plain-English verdict on what the bias looks like and why.

• Bias detection — scores articles from -10 (far left) to +10 (far right) with political position, indicators, claims, and summary
• Misinformation check — flags unverified claims against trusted sources
• Emotional language detection — features engineering using scoring of evidence vs persuasion used
• Bias quadrant chart — visualises story framing and political spectrum in a bias quadrant
• Source filtering — excludes unverified user-generated, conspiracy-leaning, opinion-based, and no editorial oversight websites
• Full article extraction — scrapes and reads full article content via Trafilatura
• Multi-article analysis — analyzes all articles in parallel using async LLM requests
• Verdict summary — calculates an overall verdict and summarises all findings across articles
