Use Cases

Built for People Who Take Privacy Seriously

Whether you're protecting personal files, running a small office, or navigating a codebase — Librarian keeps your data where it belongs.

For Individuals

Your Private AI Librarian

Keep journals, tax documents, medical records, and personal notes completely private. Librarian runs on your machine — nothing is uploaded, shared, or stored anywhere else.

Example scenario

You have 10 years of tax documents, insurance policies, and financial statements scattered across folders. Point Librarian at them, and ask: "What was my total deductible medical expense in 2024?" or "Which policy covers water damage?" You get grounded answers pulled directly from your own documents — offline.

Offline-first Works without internet — ideal for sensitive personal documents

No upload limits Index one document or thousands — your hardware is the only limit

Multi-format search Search across PDFs, spreadsheets, text files, and notes in one query

For Small Business

A Shared Knowledge Base for Your Team

Index contracts, invoices, and project files across your office LAN. One machine serves as the AI hub — up to 5 approved devices connect directly, with built-in trust management.

Example scenario

Your office has two years of contracts, supplier agreements, and compliance documents. Instead of digging through file shares, your team can ask: "What are the payment terms in the Acme Corp contract?" or "Which vendor agreements expire this quarter?" Everyone gets the same answer, sourced from the same files — without sending anything to the cloud.

Deploy to Your Network

LAN sharing One server, up to 5 users — no cloud infrastructure required

Device trust management You control which devices can connect and access documents

Privacy compliant Data stays inside your network — a simpler compliance story

For Developers

AI-Powered Code & Documentation Search

Index codebases, READMEs, design docs, and technical specifications. Ask questions across repositories, debug unfamiliar code, and accelerate onboarding — all locally.

Example scenario

You're onboarding to an unfamiliar codebase with 200+ files. Instead of grep and guesswork, ask: "How does the authentication middleware work?" or "Where is the payment webhook handler, and what events does it process?" Librarian retrieves relevant code and documentation together, giving you context faster than searching manually.

Get Started

20+ languages Python, JS/TS, C#, Java, Rust, Go, C/C++, and more

Code + docs together Search across source files and documentation in a single query

Scale your model 8B for docs, 30B+ for serious coding — switch models per task
