Summary

An open, fully offline, word-level digital reader has been developed for the Prasthanatrayi with Sankara's bhasya, the foundational corpus of Advaita Vedanta. This resource covers thirteen commentarial units, encompassing 2,971 verses, sutras, and prose sections, with 36,881 analysed word-occurrences of root text and a global dictionary of 95,587 distinct commentarial surface forms. The reader allows users to click any word in both the root text and commentary to view its split (padaccheda), morphological analysis, and gloss. Functioning also as a concordance, it retrieves all inflected, sandhi-hidden, and compound occurrences of a dictionary headword. The development utilized a hybrid pipeline combining rule-based sandhi splitting, lexicon look-ups, LLM-assisted analysis with a two-pass verification protocol, and a human-review loop. Intrinsic evaluation confirmed high-confidence analyses align with an authoritative lexicon on over 99% of attested forms. The reader is distributed as a single, self-contained HTML file.

Key takeaway

For Sanskrit scholars and Digital Humanities researchers working with complex classical texts, this digital reader offers a robust solution for word-level analysis. You should consider adopting such offline, self-contained tools to enhance accessibility and precision in textual study, especially for highly inflected languages. This approach demonstrates how hybrid AI/human systems can overcome linguistic complexities, providing reliable morphological analysis and concordance features without network dependencies.
