VaultBook isn’t just a note-taking app — it’s an offline, high-performance knowledge vault designed for professionals who live in data. Whether you’re a data scientist, analyst, engineer, or researcher, VaultBook helps you organize, protect, and instantly search through thousands of complex entries without depending on the cloud.
Built for Scale — Handles Thousands of Entries Smoothly
Traditional note apps struggle once you pass a few hundred files. VaultBook is engineered differently. Its local-first architecture uses an optimized folder structure with lightweight JSON metadata and dedicated index files for attachments and sections. This means you can store and search thousands of notes, documents, PDFs, Excel files, and datasets — all within seconds. Search is lightning-fast, even when your vault grows to gigabytes in size.
Powerful Search and Tagging Engine
VaultBook’s intelligent search engine reads beyond your text notes. It indexes content from attachments — including PDFs, Word documents, Excel sheets, and even images through built-in OCR. Every piece of data becomes instantly retrievable using keywords, tags, and labels. Need to find a specific experiment note or data source from months ago? Type a few words, and VaultBook finds it instantly — even if it’s buried inside a 500 MB attachment.
Hierarchical Organization and Tagging
VaultBook introduces a multi-level hierarchy of pages and sections, letting you group related work effortlessly — projects, datasets, experiments, incidents, or reports. Use labels and tags to build cross-project relationships. You can navigate from a top-level project page down to its smallest detail, with every file, image, and analysis step organized and interlinked.
Perfect for Sensitive and Regulated Work
Professionals working in healthcare, finance, or research often handle sensitive or regulated data. VaultBook ensures that your work stays 100% offline and under your control. Your repository lives on your own device. Notes can be password-protected and encrypted, and there’s no dependency on any server or API. For teams with compliance requirements, it’s HIPAA- and PII-ready by design.
Smart Metadata for Workflow Management
Each entry in VaultBook carries smart metadata — including due dates, expiry periods, repeat schedules, and labels. This makes it easy to manage ongoing analyses, experiments, and reports. You can even configure auto-purge policies for temporary or sensitive data, ensuring your workspace stays clean and compliant without manual cleanup.
Seamless Handling of Large Attachments
VaultBook’s deduplicated file system prevents storage bloat. Upload a 500 MB dataset once, and it will be referenced wherever needed without duplicating space. Every attachment is linked by a SHA-256 content hash, ensuring data integrity and eliminating redundancy — perfect for teams handling multiple large files across projects.
Privacy, Performance, and Control — Without Internet
VaultBook runs entirely in your browser as a standalone HTML app. No install. No sync dependency. You can open it from a USB drive, a secure laptop, or an air-gapped system. Because it runs locally, searches and updates happen in real time without latency or risk of data leaks. You control your repository, your encryption keys, and your workflow — completely offline.
