For the curious: what Carrell is built on, what comes with it, and where it runs.
Carrell is a native app written in Rust, not a web page in a window. It takes about 15 ms of work to show the first page, and searching all 66 books takes under 2 ms. All 1,189 chapters sit in one continuous scroll, and only what is on screen is ever typeset.
KJV, WEB, BSB, ASV, YLT, Darby and Webster, all public domain, side by side in parallel columns. Compare any verse across every translation at once, and import other translations you own.
On the Mac, ⌘K jumps anywhere: type “jn 3:16” or “rom 8” and the page is there. ⌘F searches, the arrow keys turn chapters, and 1 to 6 highlight the selected verse.
Turn on scroll mode on iPhone and the Bible becomes a feed of single verses, each with the screen to itself. Swipe up for the next, on through the end of the chapter. Tap a verse to highlight it, write a note or ask about it.
iPhone and iPad (iOS and iPadOS 26.1 or later, in public beta), the Mac (macOS 11 or later, Apple silicon and Intel) and Linux (64-bit x86). Android is planned. One Carrell account keeps your library in sync, reading needs no connection once you’re signed in, and everything you keep exports to Markdown or JSON.
