I review NDAs for classmates, so I built a contract-risk scanner that never lets the contract leave your laptop

Description and use

ClauseGuard is a local contract‑risk scanner that automates NDA reviews with a rulebook and a local LLM, keeping sensitive documents on the user’s laptop.

Problem

Freelancers, students, and small studios need quick, low-cost NDA reviews without uploading sensitive contracts to third‑party services.

Outcome

ClauseGuard catches all classic NDA traps with a rulebook and adds a local LLM pass for novel risks, running entirely offline with no third‑party dependencies.

Workflow

• 1. Pull a local LLM (e.g., qwen3:4b) via ollama
• 2. Clone the ClauseGuard repo
• 3. Run clauseguard scan on a contract file
• 4. (Optional) Use --no-llm for rule‑only pass
• 5. Review the generated report (markdown or JSON)
• 6. (Optional) Hand the contract to a human reviewer for final advice

The model that invented a quote. One run flagged a clause — with a quote that appears nowhere in the document.
