# What is Factagora?

> A verifiable knowledge platform for the AI era

## The Problem

AI is advancing at an incredible pace, but the 'Hallucination' problem persists. It's difficult to verify whether AI-generated information is accurate, and once misinformation spreads, it's hard to undo. News, social media, AI chatbots, how can we ensure the reliability of the information we encounter?

## Factagora's Solution

Factagora is a verifiable knowledge layer for AI. It turns unstructured text into structured, time-stamped, source-linked facts connected in a Temporal Knowledge Graph — so your AI can answer not just *what* is true, but *when* it was true and *why* it happened. Add it on top of the stack you already run; no rebuild required.

## Where Factagora fits in your stack

Keep your LLM, your vector database, and your RAG pipeline. Factagora is the grounding and verification layer you add on top — it checks what your AI is about to say against verifiable, time-aware, source-backed facts. One API layer, any framework.

    Point-in-time facts mean your AI sees what was true at the moment that matters — no stale data, no hindsight bias.

  <Card title="Answers with a reason" icon="diagram-project">
    Causal links explain *why* something happened, not just *that* it did — so AI can reason, not just retrieve.

  <Card title="Answers you can trace" icon="link">
    Every fact carries its source and a confidence score, so each answer is backed by evidence you can follow.

    A verifiable, traceable trail for the work that can't be wrong — finance, legal, healthcare, and compliance.

<Info>
  Factagora **complements** vector search, it doesn't replace it. Embeddings find what's *similar*; Factagora verifies what's *true right now* and *why*.

## Core Components

**FactBlock** is the smallest unit of trusted knowledge. It extracts key facts from unstructured text and structures them with metadata and sources.

**TKG (Temporal Knowledge Graph)** stores each fact as a time-stamped, causally linked proposition. It tracks not just *what* is true, but *when* it was true and *why* it happened — returning only the facts valid at the moment you ask, and linking causes to their effects. This is what lets Factagora answer "when" and "why" questions accurately, without later information leaking into earlier answers.

**DeepVerify** performs word-by-word verification against trusted sources, instantly checking whether each statement is verifiable.

**Fingerprint** embeds an invisible, cryptographic watermark into your content based on its causal structure, entities, timelines, and argument chains. When that content reappears (even rewritten or paraphrased), Fingerprint detects the original source with high confidence and produces an auditable evidence trail.

**Factagora Search API** is an AI trust infrastructure that reduces hallucinations by structuring information as Factblocks, each linked to a confidence score, source, and temporal context, powered by the Temporal Knowledge Graph (TKG).
