About this app

VaultLex is a privacy-first, fully offline contract analysis tool powered by cutting-edge on-device AI. Unlike cloud-based legal tools, VaultLex runs entirely on your local machine — no uploads, no servers, no data exposure. Your contracts never leave your device, period.

Powered by the latest local large language models (LLM) with on-device inference acceleration, VaultLex performs deep semantic analysis to identify hidden risk clauses, unfavorable liability terms, automatic renewal traps, vague indemnification language, and non-standard jurisdiction provisions — all in seconds.

Built for legal professionals, enterprises, and privacy-conscious businesses operating in regulated industries (finance, healthcare, defense), VaultLex ensures 100% data sovereignty. It meets the strictest compliance requirements including GDPR, HIPAA, and SOC 2 — because when your data never moves, it can never be breached.

Key features: air-gap compatible offline mode, multi-format support (PDF, DOCX, TXT), clause-level risk scoring, plain-language risk summaries, redline suggestions, and custom risk profile configuration. Supports on-device models including Mistral, Llama 3, Phi-4, and Gemma 3 via local inference backends.

VaultLex is the answer to the growing demand for AI-powered contract intelligence without sacrificing confidentiality. Whether you're reviewing NDAs, SaaS agreements, employment contracts, or M&A documents, VaultLex gives you enterprise-grade analysis with zero cloud dependency. Your vault, your rules.
