What is Coagula?
Coagula is a semantic search engine for primary source texts across religious, mystical, and philosophical traditions. Search by meaning rather than keywords; describe a concept in plain English and retrieve the passages that match most closely, regardless of tradition, vocabulary, or era.
The name comes from the alchemical maxim "Solve et Coagula"; dissolve and reconstitute. The corpus spans multiple millennia and traditions; the tool is designed to surface structural connections between them.
How to Use It
Search
Type a concept, idea, or question in plain English, such as "the nature of the soul" or "what happens after death." Results are ranked by meaning, not keywords, so passages discussing the same concept in different language still appear. Use the tradition filters to narrow results, the concept buttons in the sidebar to browse by theme, and the similarity meter (colored boxes) to gauge match quality.
Browse
Click Browse in the nav to see the entire archive organized by tradition. Click any text to read it chapter-by-chapter with a sidebar for navigation. Use this when you want to read a complete text rather than searching for specific ideas.
Find Similar
The find-similar button appears on every passage in search results, browse mode, and find-similar results. Click it to find passages across the entire corpus that express similar ideas, regardless of tradition or vocabulary. The source passage is pinned at the top with a gold highlight so you can compare directly.
