About

Defacta is an independent verification layer that checks AI-generated or external text against credible sources before it informs decisions, publications, or filings. It replicates the human verification process as a structured, multi-stage pipeline, using LLMs only to accelerate specific steps while constraining them with fresh data retrieval and source-grounded analysis. The platform extracts key claims from pasted text, articles, URLs, or AI outputs and checks them against independent sources, fact-checking registries, and credibility signals. It flags hallucinations, fabricated citations, unsupported assertions, bias, manipulation patterns, and misleading framing. Reports combine factual findings, source metadata, risk indicators, and recommended actions. Every report is timestamped with SHA-256 hashes, creating a durable audit trail. Users can edit text, generate repair prompts, re-check changes, and compare versions.
