Frequently Asked Questions

No. Librarian runs entirely on your local machine. Your documents are indexed and stored in a local vector database on your own hardware. Nothing is uploaded, transmitted, or shared with any external server. In Offline mode, the application has zero network access.

Agentic RAG (Retrieval-Augmented Generation) is an advanced approach where the AI agent performs multiple retrieval steps to answer your question. Unlike simple RAG that retrieves once and responds, Agentic RAG can break complex questions into sub-queries, gather evidence from different parts of your documents, and synthesize a more complete answer — reducing missed details and hallucinations.

Yes. Librarian works with any model available through Ollama. You can switch between models depending on your task — smaller models (8B parameters) for fast document Q&A, or larger models (30B+) for complex coding questions. The choice is yours, and you can change models at any time.

For basic code questions and documentation lookup, 8B models work well. For serious coding assistance — debugging, refactoring, or cross-repository analysis — we recommend 30B+ parameter models. Librarian's hardware requirements page has specific recommendations by use case.

Librarian supports PDF, Excel (XLSX/XLS), CSV, plain text, Markdown, and common code files across 20+ programming languages including Python, JavaScript, TypeScript, C#, Java, Rust, Go, and more. Your documents are parsed and indexed locally for fast retrieval.

Yes, with the Family plan. One machine runs Librarian as a LAN server, and up to 5 approved devices on the same local network can connect to it. Access is controlled through built-in device trust management — you decide which devices are allowed.

For basic document search with small models: 8GB RAM, a modern quad-core CPU, and 10GB free disk space. For larger models and coding assistance: 16–32GB RAM and a dedicated GPU (NVIDIA recommended) significantly improves performance. See our full hardware requirements on the Product page.

After completing your purchase through Stripe, you'll receive your license key immediately on the confirmation page and via email. The key activates your chosen plan and is tied to your account for easy management.

Yes. The Local Trial plan gives you 30 days of full access at no cost. You can index documents, run queries, and evaluate Librarian on your own hardware before deciding to subscribe.

Librarian currently supports Windows (10 and later). Linux and macOS support are in active development and coming soon. The application requires Ollama to be installed for local model execution.

No. Your subscription stays active as long as payments continue. Librarian keeps a 30-day offline grace period so you can use the app without an internet connection. If more than 30 days pass without the app contacting our servers, you'll be asked to connect to the internet briefly on next launch. Once connected, your license re-validates instantly and everything resumes — no data is lost, no re-installation needed.
