Buddhist Digital Text Platform — 10,500+ texts, 613 sources, trilingual cross-canon, AI Q&A (RAG), knowledge graph, full-text search

What it solves

FoJin provides a unified, verifiable platform for querying the Buddhist canon. It solves the problem of Buddhist texts being scattered across hundreds of disparate databases with different interfaces and languages, making it difficult for researchers and practitioners to find specific passages or compare translations across different traditions (Chinese, Pali, Tibetan).

How it works

FoJin aggregates over 600 data sources into a single searchable corpus of 10,500+ texts. It uses Retrieval-Augmented Generation (RAG) over 680K+ embedded passages to power its AI assistant, "XiaoJin," which provides answers grounded in the scriptures with clickable citations. The system employs a trilingual cross-canon alignment pipeline (using LLMs and vector similarity) to link corresponding passages across Chinese, Pali, and Tibetan canons, allowing for side-by-side parallel reading. It also includes a knowledge graph of 110K+ entities and 32 integrated dictionaries for term lookup.

Who it’s for

  • Buddhist scholars and researchers needing a centralized, cross-canon research tool with verifiable citations.
  • Students of Buddhism seeking plain-language answers to complex scriptural questions.
  • Practitioners wanting to explore the Buddhist canon and compare translations across different languages.
  • AI developers who can use the fojin-mcp server to integrate FoJin's verified corpus into other AI assistants.

Highlights

  • Verifiable AI Q&A: Answers are grounded in the canon with deterministic guards to prevent hallucinations and ensure citations point to actual retrieved sources.
  • Trilingual Cross-Canon Alignment: The first LLM-driven system to align chunks and sentences across Chinese, Pali, and Tibetan canons.
  • Massive Aggregated Corpus: Access to 10,500+ texts from 613 sources, including CBETA, SuttaCentral, and 84000.
  • MCP Server Integration: Allows AI assistants like Claude and ChatGPT to call FoJin's tools for cited, non-hallucinated Buddhist answers.
  • Knowledge Graph & Dictionaries: Includes a map of 110K+ entities and 32 authoritative dictionaries for deep terminology research.
