Documentation Overview

FoJin 佛津

Ask the Buddhist canon — get cited, verifiable answers.

AI Q&A grounded in the world's largest open aggregation of Buddhist texts: 600+ sources, 30+ languages, trilingual cross-canon retrieval — every answer linked back to its source passage.

Ask a question in plain language and FoJin's assistant "XiaoJin" answers from the canon itself — Retrieval-Augmented Generation over 670K+ embedded passages, optional cross-encoder reranking and root-sutra recall, clickable 【《sutra》juan N】 citations that open the exact source text, anti-hallucination guards, and a citation drawer with side-by-side 汉 / 巴利 / 藏文 cross-canon parallels. You can also ask in the voice of 15 historical Buddhist masters, each scoped to their own tradition's scriptures.

What makes those answers trustworthy is the corpus underneath. FoJin aggregates 612 data sources into one searchable platform — 10,500+ texts with 19,000+ volumes of full content in Classical Chinese, Pali, Tibetan and Sanskrit, the first LLM-driven trilingual cross-canon parallel reading platform (CBETA × SuttaCentral × 84000) with LLM-verified chunk-level alignment, a 110K+ entity knowledge graph on a Deck.GL geo map, and 39 dictionaries with 747K entries. Every feature exists to make the answers more grounded — and to let you go deeper once you have one.

FoJin is built to be open, cross-canon, verifiable Buddhist knowledge infrastructure — not just a site to read, but a corpus other tools can call. Every passage carries a stable, resolvable cross-canon URN (fojin:cbeta/T0001.1), and the fojin-mcp server lets AI assistants (Claude, ChatGPT, any MCP client) answer from FoJin's cited passages directly — hosted at mcp.fojin.ai, anonymous, no key required. Any model can also check its own work through the open /api/verify/quote endpoint: hand it a sentence and a citation, and it answers is this quote real and is the citation right as two separate questions. See fojin.app/agents.

FoJin — Global Buddhist Digital Text Platform

Why FoJin?

Buddhist texts are scattered across hundreds of databases worldwide — CBETA, SuttaCentral, BDRC, SAT, 84000, GRETIL, and many more. Each has its own interface, language, and data format. When you have a question — "what does the Heart Sutra mean by 'form is emptiness'?", "how do the Pali and Chinese versions of this passage differ?" — you spend more time hunting for the right passage than understanding it.

FoJin answers the question for you. Ask in plain language; XiaoJin retrieves the relevant passages from 612 sources and answers with clickable citations you can verify. Everything else FoJin does — full-text reading, cross-canon alignment, the knowledge graph, 39 dictionaries — exists to make those answers more grounded, and to let you go deeper once you have one:

What you need	How FoJin helps
Ask a question, get a sourced answer	AI Q&A ("XiaoJin") — RAG over 670K+ passages, reranking, root-sutra recall, clickable 【《sutra》juan N】 citations, cross-canon citation drawer, anti-hallucination guards
Trust the answer	Verifiable answers — deterministic citation whitelist + verbatim-quote downgrade + per-answer trust state; ~98% of citing answers served-trustworthy at temp 0
Research a hard, multi-step question	Research Assistant (`/research`) — plans across corpus + dictionaries + knowledge graph, then synthesises a cited answer behind the same guards
Call FoJin from an AI assistant	MCP server — hosted at `mcp.fojin.ai` (no install, no key) or `uvx fojin-mcp`; 8 read-only, URN-addressable tools for Claude / ChatGPT
Check whether a quotation is real	Open verbatim verification (`/api/verify/quote`) — for any sentence, not just ours: exact / near-miss / absent, with a character-level diff and the right juan when the citation points at the wrong one
See how the tradition read a passage	Commentary alignment (`/api/commentary/passage`) — for one passage, what the historical commentators wrote on it, anchored to juan and line
Listen while you read	Read-aloud (`/read-aloud`) — sentence-by-sentence highlighting synced to audio, lock-screen playback
Ask in a master's voice	Master Persona Mode — 15 historical masters, each with tradition-scoped RAG
Find a sutra across databases	Multi-dimensional search across 10,500+ texts from 612 sources
Read the full text online	8,900+ texts with 19,000+ volumes of full content, CBETA-style layout
Compare translations	Parallel reading in 30+ languages side by side
Compare sutras across Buddhist canons	Trilingual cross-canon parallel reading — 4,000+ LLM-verified chunk alignments across Chinese / Pali / Tibetan covering Heart Sutra, Vimalakīrti, Lotus Sutra (法华 ↔ Toh 113, 259 pairs), 8,000-verse Prajñāpāramitā (小品般若 ↔ Toh 11, 127 pairs), Satipaṭṭhāna + the full Āgama ↔ Nikāya corpus (MN/DN/SN/AN), Dhammapada
Look up Buddhist terms	39 dictionaries, 747K entries (Chinese/Sanskrit/Pali/Tibetan/English)
Explore relationships	Knowledge graph with 110K+ entities and 27,900+ relations (22K+ lineage chains)
Discover similar texts	Semantic similarity powered by 670K+ embedding vectors (pgvector + HNSW)
Explore Buddhist geography	Knowledge Graph Map — geo-enabled entities, monastery locations, lineage arcs on Deck.GL
Track source updates	Activity Feed — real-time updates from 612 data sources
Explore history visually	Timeline & Dashboard — dynasty charts, translation trends, category analytics
Save and organize	Collections, bookmarks, annotations for personal study
Cite in research	Citation export (BibTeX, RIS, APA) for academic use

Quick Start

bash

git clone https://github.com/xr843/fojin.git
cd fojin
cp .env.example .env        # edit POSTGRES_PASSWORD before starting
docker compose up -d         # database migrations run automatically

Then visit: http://localhost:3000

API docs at http://localhost:8000/docs

After first startup, the platform has the database schema and source metadata but no text content. To import texts from public data sources:

bash

# Import CBETA catalog (auto-scans local xml-p5 directory or fetches from remote)
docker exec fojin-backend python scripts/import_catalog.py

# Import CBETA full text content (requires xml-p5 repository)
docker exec fojin-backend python scripts/import_content.py --all --xml-dir /data/xml-p5

# Generate embeddings for AI Q&A (supports incremental processing)
docker exec fojin-backend python -m scripts.archive.misc.generate_embeddings --source cbeta

# Import SuttaCentral Early Buddhist Texts
docker exec fojin-backend python scripts/archive/imports/import_suttacentral.py

# See all available importers (one-off importers live under archive/)
ls backend/scripts/archive/imports/

Each importer downloads data directly from the original source (CBETA, SuttaCentral, etc.) — no data is bundled in this repository.

Use FoJin from your AI tools (MCP)

FoJin's verified, cross-canon corpus is callable directly from AI assistants (Claude Desktop, ChatGPT, or any MCP client) via the published fojin-mcp server — so the assistant answers Buddhist questions from FoJin's cited passages instead of hallucinating.

Point any MCP client at the hosted endpoint — nothing to install, no key to get:

Terminal

claude mcp add --transport http fojin https://mcp.fojin.ai/mcp

Or run it locally over stdio against your own instance:

bash

uvx fojin-mcp                 # zero-install run
# or: pip install fojin-mcp && fojin-mcp

It exposes eight read-only tools over the public API, each returning passages with a stable, resolvable cross-canon URN (fojin:cbeta/T0001.1):

Tool	What it does
`search_corpus`	Semantic search across the aggregated canon
`read_passage`	Read a specific text / volume
`get_parallels`	Cross-canon parallels (汉 ↔ 巴利 ↔ 藏) for a passage
`lookup_dictionary`	Term lookup across 39 dictionaries
`lookup_entity`	Knowledge-graph entity facts
`resolve_urn`	Resolve a FoJin URN to its source location
`verify_quote`	Verbatim check — is this sentence really in the canon, and really where you said? Answers "is the quote real" and "is the citation right" separately, with a character-level diff when it is close but not exact
`commentaries`	For one passage, what the historical commentators wrote on it — anchored to juan and line
