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.

About

Gretchen AI is a verification platform from Berlin for organisations that cannot afford to be wrong about what is real. It analyses images, video, audio and text in real time and detects more than 80 types of deepfakes and synthetic media. Detection alone is not enough. Gretchen AI also evaluates context and source credibility and examines metadata and provenance, because authentic material can mislead as well. Every result is explainable and ready for editorial or official use. Gretchen AI can be embedded into existing IT infrastructure and offers a social media integration, so content can be verified right where it spreads. The platform is GDPR-compliant and serves public authorities, security and defence, newsrooms and image agencies. Gretchen AI was used by the State of Berlin to help citizens check suspicious content during the 2026 Berlin state election.
