Ask a question about Buddhist scripture in plain language and get an answer that points to the exact passage it came from. FoJin brings thousands of texts from hundreds of digital libraries into one search box, so a reader no longer jumps between a dozen archives with different layouts. The AI assistant, called XiaoJin, answers with clickable citations that open the original text, and it can also reply in the voice of historical masters scoped to their own tradition. Search covers classics, translators, and catalog numbers, with filters by country and collection. Reading pages show full text, and parallel views line up translations in many languages, with Chinese, Pali, and Tibetan versions of the same sutra side by side. Thirty-nine dictionaries answer term lookups, a knowledge graph maps people, lineages, and places, and a data source directory shows what each collection offers. Readers can save collections, bookmarks, and annotations, then export citations in BibTeX, RIS, or APA. A read-aloud mode highlights each sentence in sync with audio. Quote verification confirms that a sentence really exists in the canon, and where.
