Ever wished you could search the Hebrew Bible or Greek New Testament by morphological features — without buying expensive software? Parabible is a free, open-source, browser-based tool that lets you read and search the original languages of Scripture with remarkable sophistication.^1 Built on morphologically parsed and tagged texts, it displays the BHS (Hebrew), Rahlfs LXX (Greek Septuagint), SBL Greek NT, and NET English translation side by side — no installation required.^2
Click any word in the original language and Parabible reveals its part of speech, tense, person, number, gender, and semantic domain. From there, you can build multi-term searches across phrases, clauses, sentences, or entire verses — filtering by specific books to narrow your results.^2 Under the hood, the search engine uses Clickhouse (an OLAP database) with a custom Rust-based function for blazing-fast queries across the full biblical corpus.^3 A next-generation server rewrite in TypeScript/Deno is in active development, with a modular data pipeline that supports adding new text modules.^4
Parabible was created by James Cuénod, who holds a PhD in Biblical Theology (Old Testament) from Wheaton College and now serves as Senior AI Translation Technologist at Seed Company, where he consults on AI tools for Bible translation projects worldwide.^3 He originally built the tool to help with his own exegetical research, and the entire codebase is open source on GitHub with 11 repositories.^6 The tool has daily active users and continues to receive data pipeline updates.^3
