Every day, educators and students face a problem that keeps getting worse: AI makes it easier to generate text, but no easier to evaluate it. Citation checklists, CRAAP tests, and source evaluation frameworks exist — but applying them manually is slow, inconsistent, and often skipped entirely.
Sabia Librarian exists to make professional-grade source evaluation accessible to every librarian, teacher, and student — regardless of whether they have a library science degree or access to a reference desk.
The evaluator doesn't replace judgment. It supports it. You'll see exactly why each source received its score — so you can teach the framework, not just deliver a verdict.

It returns a score and a detailed breakdown — not a black box.
