Setup Snapshot

git clone https://github.com/kvssyugal/trustcheck.git
  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Full README

TrustCheck — AI Hallucination Detector

A 3-agent AI system that fact-checks any AI-generated text in real time and returns a trust score out of 100, with cited sources.

🌐 Live demo: trustcheck-production-a32e.up.railway.app

What it does

Paste any AI-generated answer (from ChatGPT, Claude, Gemini, anywhere). TrustCheck:

  1. Extracts every factual claim in the text
  2. Searches the live web for evidence on each claim
  3. Verifies each claim against the retrieved sources
  4. Returns a Trust Score out of 100 with the supporting (or contradicting) citations

Built to address the single biggest blocker to deploying LLMs in production: hallucinations.

How it works

Three CrewAI agents collaborating in sequence:

| Agent | Role | |---|---| | Claim Extractor | Parses the input text and isolates each verifiable factual claim | | Researcher | Performs targeted web searches per claim and collects source snippets | | Verifier | Cross-checks each claim against retrieved evidence and assigns a confidence score |

The aggregated result is rendered as a per-claim breakdown plus an overall Trust Score.

Tech stack

  • Language: Python
  • Agent framework: CrewAI
  • LLM: OpenAI API (GPT-4 family)
  • Backend: FastAPI
  • Frontend: lightweight HTML/JS
  • Deployment: Railway

Run it locally

git clone https://github.com/kvssyugal/trustcheck.git
cd trustcheck
pip install -r requirements.txt
cp .env.example .env   # add your OpenAI API key
python app.py
# open http://localhost:8000

Roadmap

  • [x] Multi-agent claim verification
  • [x] Public deployment on Railway
  • [ ] Anthropic Claude support for verifier agent
  • [ ] Browser extension for one-click checking
  • [ ] Domain-specific fact-checking modes (medical, financial, legal)

Why I built this

Hallucinations remain the #1 reason teams hesitate to ship LLM features. Most existing fact-checkers are single-shot prompts that themselves hallucinate. I wanted to test whether agent-based verification with explicit web grounding could reliably outperform a single-prompt approach. Early results suggest it does — work in progress.
