Make scripture clickable · est. 2026
For Kindle, Paperwhite & Scribe

Every scripture reference,
a tap away.

Drop in any study book or commentary. We'll find the references — Romans 8:28, 1 Cor. 13:4–7, cf. Ps 23 — and weave them into a Kindle-ready EPUB with the full Bible bundled inside.

Your books never leave this page. Everything happens in your browser.

Specimen · Detected referencesfol. 1.r

The whole of Christian discipleship hangs on a single sentence — that Romans 8:28 is true, that all things work together for good. Paul does not promise comfort; he promises providence.

See also Ps 23:4, the long meditation in Job 38–41, and the apostle's own coda in 2 Cor 4:17.

In three movements

From a flat manuscript to a living book.

No machine learning, no cloud calls, no surprises. A deterministic three-step pass over your manuscript that you could run on a plane.

i.

We read

Your EPUB is unzipped in memory. We walk every chapter looking for references in over 200 abbreviated forms — Romans 8:28, Rom. 8.28, Ro 8:28–30, and more.

ii.

We weave

Each match becomes an anchor that points to a specific verse. We bundle a full Bible alongside your book — or, if you prefer, render each verse as a popup footnote so the file stays slim.

~6,000 hyperlinks per book
iii.

We deliver

The result is a fresh, valid EPUB ready for Send-to-Kindle, calibre, or any reader. Scripture travels inside your book — no second file, no separate library entry, just your book with every reference clickable.

Before
Chapter 4 · The Grace of God67 %

The deepest mystery of the Christian gospel is that God justifies the ungodly — see Romans 4:5 for Paul's exact phrasing, which echoes Habakkuk 2:4 and Christ's parable in Luke 18:9–14.

It is not that God overlooks our sin; it is that, in 2 Corinthians 5:21, he transfers it. The exchange is the gospel.

And so the cry of Psalm 51 is not a relic of pre-Christian piety but the daily prayer of every saint…

Reading RC Sproul on Kindle and being able to actually tap every verse he cites — it changed how I study.

Q · 01Does my book really stay on my computer?+
Yes. There is no server side to this app. The page you're reading downloads a small JavaScript bundle and does the entire conversion locally in your browser tab. You can confirm by opening DevTools → Network: you'll see one HTML, one CSS, one JS, and zero outbound requests during processing.
Q · 02Which Kindle models does this work on?+
Bundle mode works on every Kindle made in the last decade — Basic, Paperwhite, Oasis, Scribe — and on the Kindle apps for iOS, Android, Mac, and Windows. Popup mode works on Paperwhite 4+ and all current devices, but older Kindles render the popup as plain text.
Q · 03What translation is bundled?+
The World English Bible, which is in the public domain and includes the deuterocanonical books.
Q · 04Is this free? What's the catch?+
Free, open-source, no ads, no tracking, no accounts, no upload. The catch is that one person maintains it. If it saves you hours, a voluntary donation on Ko-fi keeps it going.
