Premium research
Industry-standard desktop software with a massive library. Powerful but expensive ($299–$9,999), steep learning curve, and no AI debate or apologetics features. Best for academic research — not for real-time answers.
Scholarly tool
Excellent original language tools, especially for Hebrew and Greek morphology. Desktop-focused, module-based pricing ($59–$699). No AI, no debate features, no worldview comparison. A scholar's tool, not an apologetics engine.
Basic reader
Clean mobile Bible reader with limited study tools. Free tier is very basic. No AI, no primary source library, no sermon builder. Good for reading — not for research or debate.
Free Strong's reference
Excellent free resource for Strong's concordance and basic word studies. No AI, no Talmud/Midrash/DSS sources, no sermon builder, no apologetics features. A reference tool, not a research engine.
AI-powered theological research engine
1,800,000+ curated primary sources across Talmud, Midrash, Dead Sea Scrolls, Church Fathers, and more. AI Sermon Builder, Hebrew/Greek analysis, worldview comparison, and a knowledge graph that finds connections humans miss.

Self-Learning
ReProof.AI combines 1.7M+ indexed sources with a multi-agent AI research engine, Hebrew/Greek analysis, and an AI Sermon Builder — starting free. Unlike Logos ($299+) or Accordance ($59+), ReProof.AI is subscription-based with no upfront cost.
ReProof.AI's AI Sermon Builder generates complete sermon frameworks with original language breakdowns, cross-references, and Rabbinic commentary in minutes. Logos requires manual research across purchased books. For quick, source-cited sermon preparation, ReProof.AI is faster and more affordable.
Yes — ReProof.AI integrates with BibleHub for live Strong's concordance lookups, interlinear analysis, and lexical data for both Hebrew and Greek. All accessed through natural conversation with Enoch.
Ask Enoch anything — from Hebrew word studies to sermon outlines to comparative theology.
