Bible chapter summary.
Type a chapter reference and get a brief summary in the Kerygma voice — what happens, the structure, the theological weight — plus the chapter\'s themes, key verses, and how it connects to wider Scripture. Generated on demand by Claude (Anthropic). Useful as a study orientation before you read the chapter itself, not as a replacement for it.
Type a chapter reference above and tap "Summarise". The summary appears here in a few seconds.
How this tool works
Each summary is generated on demand by Claude — Anthropic\'s AI assistant — using a prompt that pushes for the Kerygma voice (literate, grounded in the text, no preacher-speak). The model returns a 150–220 word summary plus a few themes, key verses, and connections to other parts of Scripture. The whole round trip takes 3–8 seconds depending on the chapter\'s complexity.
Two important caveats. First, AI-generated summaries are summaries — they shouldn\'t replace reading the actual chapter. Second, AI occasionally gets details wrong; if anything in a summary seems off, check the chapter itself before quoting it. We rate-limit the endpoint (20 requests per minute, 200 per day per IP) to keep the AI bill predictable.
FAQ
What chapter format is accepted?
Standard "Book Chapter" — John 3, Romans 8, 1 Corinthians 13, Psalm 23. Single chapter only, no verse range. The tool rejects formats like "John 3:16" (use the verse-lookup tool for that) or "John 3-4" (give it one chapter at a time).
How accurate are AI summaries?
Generally good for major chapters with well-known content (John 3, Romans 8, Psalm 23). Occasionally the model invents details, especially for less-frequently-quoted chapters. The summaries are study orientations, not authoritative commentary. Always read the chapter itself before teaching from a summary.
What model is used?
Claude Haiku 4.5 — Anthropic\'s fast tier, good for ~200 word generations at low cost (~$0.003 per request). The same model that drives Kerygma\'s third-tier fallback for the trivia chain.
Is there a rate limit?
Yes: 20 requests per minute and 200 per day per IP. Generous for a study session, tight enough to discourage automated scraping of the entire Bible.
Why not a pre-generated chapter index?
Trade-off. Pre-generating all 1,189 Bible chapters would let us serve summaries instantly with no AI cost per request, and lets us curate quality more carefully. On-demand generation costs more per request but stays fresh with each new model release and doesn\'t commit us to a single take. We may build a pre-generated index later; for now, on-demand keeps it simple.
