About the Project — LexiGuard

Inspiration

LexiGuard was inspired by a real gap I noticed in legal-tech tools: most systems either summarize contracts or flag keywords, but fail to explain why something is risky and how to fix it. Compliance failures under regulations like GDPR, CCPA, and HIPAA are expensive, yet legal reviews are slow, manual, and inconsistent. I wanted to build an AI system that reasons like a compliance analyst, not just a text summarizer.

What I Learned

Through this project, I learned how to:

  • Design prompt-driven legal reasoning using large language models
  • Perform semantic clause extraction without labeled datasets
  • Map natural language clauses to regulatory intent, not keywords
  • Build a full-stack AI system that converts analysis into execution-ready remediation

- Control hallucinations using grounded prompts and structured JSON outputs

How I Built It

LexiGuard is a full-stack AI application built with:

  • Flask for backend APIs
  • Google Gemini for long-context legal reasoning
  • PDF/DOCX/TXT parsers for document ingestion
  • Structured JSON pipelines for clause extraction, compliance analysis, and remediation planning
  • Tailwind CSS + JavaScript for an interactive, real-time UI

The system follows a clear pipeline:

  1. Upload legal document
  2. Extract semantic clauses
  3. Perform cross-regulation compliance analysis
  4. Generate risk heatmaps

5. Produce a prioritized remediation roadmap

Challenges Faced

One major challenge was preventing AI hallucination in legal outputs. I solved this by:

  • Constraining Gemini with explicit regulatory context
  • Forcing schema-validated JSON outputs
  • Tying every finding directly to extracted document text

Another challenge was translating complex legal risks into actionable steps, which led to the remediation engine that breaks fixes into 7-day, 30-day, and long-term actions.

Outcome

LexiGuard doesn’t just analyze legal documents — it explains risks, prioritizes them, and tells organizations exactly how to fix them before regulators do.
