Apps

VaultSafe’s app ecosystem represents a breakthrough in secure, AI-powered personal data processing. Our platform enables sophisticated applications that transform document metadata into structured, actionable intelligence—all while maintaining the highest standards of privacy and security.

Architecture overview

VaultSafe Apps operate on a sophisticated pipeline that combines advanced AI models with zero-trust security principles:

  1. Document metadata extraction — When files are uploaded, our AI analysis engine (powered by state-of-the-art computer vision and NLP models) extracts rich metadata: document classification, entity recognition (people, dates, locations), structured key-value pairs, and semantic descriptions. This metadata layer powers both search/chat and app processing.

  2. Agent prompt execution — Each App defines an agent prompt: sophisticated instructions that guide our AI models to extract app-specific structured data from the metadata. These prompts leverage advanced few-shot learning and structured output capabilities, enabling precise extraction without exposing raw file content.

  3. Secure data storage — Extracted data is stored in a per-user, per-app namespace within our zero-trust architecture. Each app’s data is isolated, encrypted, and accessible only to the user who owns it.

  4. Intelligent widget rendering — Apps define widgets that present extracted data through configurable UI components (e.g., sorted lists, timelines, dashboards). Widgets are dynamically rendered based on app-defined schemas and display preferences.

Pipeline: Document → AI Metadata Extraction → Agent Prompt → Structured Data → Secure Storage → Widget UI

Security guarantee: Apps never access raw files or user credentials. They operate exclusively on pre-extracted metadata within isolated execution environments.

App types

  • Default apps — Pre-installed applications (e.g., Birthdays) that run automatically on all processed documents. These apps are developed by VaultSafe’s research team and represent best practices in secure personal data processing.

  • Optional apps — Additional apps available in our catalog that users can enable. Once enabled, they process new documents and provide dedicated widgets for their extracted data.

Users can add or edit app entries (e.g. birthdays, reminders) from the Apps page using simple forms—no technical setup or JSON required.

Data schema and extensibility

Each App defines a schema that specifies the structure of extracted data (e.g., { person_name: string, date: ISO8601, source: string }). Schemas enable:

  • Type-safe data storage and retrieval
  • Validation of extraction outputs
  • Future extensibility for custom user-defined fields

Our schema system supports complex nested structures and is designed to evolve with our platform’s capabilities.

Marketplace and third-party development

VaultSafe is building an open ecosystem for personal data applications. Third-party developers can create apps that integrate seamlessly with our platform:

  • App packages — Self-contained bundles (folder or zip) containing app metadata, agent prompts, schemas, and widget definitions
  • Unified deployment — Single-package format ensures consistent installation and execution across our infrastructure
  • Secure execution — Apps run in isolated environments with strict access controls, ensuring user data privacy
