Defacta

Defacta is a content detector tool. Defacta checks AI answers and any text for factual accuracy, source credibility, bias and manipulation, returning a structured, timestamped report. It targets individuals, journalists, analysts and organizations, with a free daily allowance.

Defacta is a web-based verification tool that examines AI-generated answers and any other piece of text before the reader acts on it. Instead of returning a simple true or false, it extracts the individual claims, compares them with sources, and produces a structured report with one traceable verdict. The aim is to catch hallucinated facts, fabricated citations, slanted framing and known misinformation at the point between reading something and making a decision. The analysis runs in four layers. Factual verification checks claims against credible sources and authoritative databases. Source credibility rates each cited source on reliability, track record and relevance, and flags anonymous or weak ones. A bias and manipulation layer looks for loaded framing, selective omission and persuasion tactics, then scores bias across several dimensions. The final layer cross-references the text against fact-checking registries and misinformation databases, with every verdict timestamped. The homepage offers a sample news-style article that can be loaded and run to see the report format. The audience is split into three groups. Individuals can paste an AI answer about health or money, or an article they are about to share, and receive a check without technical knowledge. Professionals such as journalists, editors, analysts, researchers and lawyers can offload the mechanical work of cross-referencing and citation checking, with assessments described as taking under a minute. Organizations get a documented, timestamped trail, with compliance documentation mapped to several EU AI Act articles. An API and MCP server are listed as coming soon. Among alternatives, Defacta sits closer to a fact-checking workflow than to a general chatbot or an AI-content detector. Its stated position is to support human judgment rather than replace it, and it explicitly makes no claim to ultimate truth. A limited free tier is available for everyday readers, while access for heavier use is requested through signup.
