Description

Defacta is an independent verification layer that checks AI-generated and external text against credible sources, databases, and fact-checking registries. It identifies hallucinations, unsupported claims, fabricated citations, bias, and manipulative framing through a structured, multi-stage pipeline. The platform produces source-backed reports with findings, evidence records, and audit trails including SHA-256 hashed timestamps. It supports revision workflows, annotation, and export to multiple formats. Defacta serves analysts, compliance teams, journalists, and enterprise AI pipelines where accuracy is critical, connecting personal verification and agent-to-agent workflows through API, MCP server, and browser extension integrations.

Description

Lenz is a robust API designed for audit-level fact-checking of AI-generated content, aimed at teams that require verification of factual assertions prior to presentation to clients or customers. This tool analyzes various forms of text, such as drafts, memos, or model answers, identifying factual claims that can be substantiated by credible public sources and providing a detailed outcome for each assertion. Its operational framework is built upon four key API functions: extracting claims that can be verified, performing a rapid multi-model assessment of these claims in bulk, elevating ambiguous statements to a comprehensive verification process, and facilitating follow-up inquiries that are based on the verification findings. The complete verification process is structured into five distinct stages: defining the issue, conducting research, engaging in debate, undergoing a panel review, and reaching a conclusion. Lenz meticulously searches through public information, evaluating evidence based on factors like authority, relevance, and timeliness, while also employing models from various vendors to present arguments for both sides of a claim. Ultimately, it delivers a verdict, a confidence score, references to cited sources, and a trace of the reasoning that allows users to conduct their own audits, ensuring transparency and reliability. With Lenz, teams can enhance their decision-making processes by ensuring all claims are thoroughly vetted before they reach their audience.
