What is Deep Dive Bible?
Deep Dive Bible is a home for Bible study, both in groups and individually. Each group reads the Bible together and talks it over—or save your notes for yourself (all exportable).
With Bible studies, each day has its reading, which you can read or listen to. With an account, you can save your place and make plans to read chapters (multiple times), or commentaries; the system tracks your progress.
With comments from about thirty classic commentaries and many other helps: ten English translations, the Hebrew and Greek, and encyclopedias, dictionaries, lexicons, and maps beside the verse you are reading.
Each group’s conversation is organized by topic and works like a group chat. Every verse mentioned in it opens in the Bible reader.
Why another Bible app?
We are people who read the Bible a lot, daily. Our focus is on excellent user experience. Everything “just works.” And we are a Christian ministry devoted to Gospel truth; Deep Dive Bible will always be free, funded by donations only, and we will never sell out. We have combined, in one app,
- intelligent tracking of your current reading place and other data and settings across all devices
- reading plans
- dedicated personal and group study areas, with full-featured, secure chat, deeply integrated with the Bible
- group conversations by topic, with replies, reactions, polls, and photos
- a daily reading for each group, with a place to discuss it

History
Larry Sanger started In-Depth Bible Study in April 2020 on YouVersion. It moved to Telegram in February 2023.
This site was built to replace Telegram as the group’s home. The Bible reader and its resources were, at first, a nice add-on. The site was conceived, designed, and directed by Larry Sanger and built by Claude, an AI made by Anthropic. Its software is called Chatiferous; it is free software, under the GPL-3.0.
In-Depth Bible Study moved here in September 2026, bringing every message it had written on Telegram since the first. The site opened at larrysanger.org/bible/ and moved to deepdivebible.org on October 1, 2026. It is now becoming a home for other Bible studies too, each with its own topics and readings.
