The intelligence layer for your library.
Upload your collection. Our AI reads the abstracts, enriches the metadata, and provides a secure, embeddable chat interface for your users to explore the catalog naturally.
A complete library AI assistant
Ditch the legacy systems. Libra brings agentic search and modern interfaces to your existing collection.
Bulk Ingestion
Upload legacy MARC 21 files or simple CSVs. Our fault-tolerant background queue handles thousands of items automatically while respecting API rate limits.
Hybrid Search
We don't just do basic vector lookups. We combine Dense PgVector search with Sparse full-text matching for incredible accuracy via Reciprocal Rank Fusion.
Drop-in Widget
Copy a single <script> tag and paste it on your website. No complex API integration required. A floating AI assistant ready instantly.

Autonomous Cataloging
You provide an ISBN, our agents do the rest. The system automatically reaches out to Google Books and Semantic Scholar to build a rich metadata profile, writes a summary using LLMs, and embeds the entire context into PgVector.
Embed anywhere in seconds
Transform your static library website into an interactive reference desk. Our lightweight JavaScript widget injects an isolated iframe, ensuring perfect security and compatibility across any CMS or custom build.
