Libra Esoterica Pro
Free members browse the whole library. Pro members put questions to it — an AI research console that reads across the catalog and the public full texts, cites the passages it relies on, and finds books by what they are about.
$9 a month or $79 a year (save 27%). Cancel anytime.
About $6.58 a month, billed once a year. Save 27%.

What Pro adds
Put a question to the catalog and the public-domain full texts at once — a symbol, a practice, a name that keeps recurring — instead of opening books one at a time.
Responses cite the passages they draw on, down to the page of the source scan, so you can read the original and judge it yourself.
Semantic search finds the treatise on planetary hours whether or not the word “astrology” is anywhere in its record.
Compare plans
Full-text ingestion, embeddings, and AI answers are the expensive part. Pro covers them and keeps the catalog open to everyone.
