Bible Study Tools

Browse, search, and comment on Scripture using your local Bible library.

~5 minutes to learn

Overview

Comment Coach includes a full Bible study environment. You can browse chapters, look up references, search by keyword, by pattern, or by the Hebrew and Greek behind the text, compare translations side by side, select verses, and write comments — all from your browser, even offline.

All Bible data is stored locally on your device in IndexedDB. Nothing is uploaded to the server. Two free translations are set up for you on first visit: ASV (English) and RV1909 (Spanish). After that they are yours offline like any other.

Installing Bibles

01

Open the Bible Catalog

Go to Bibles → Catalog. The catalog lists 168+ translations from multiple sources, grouped by language, with your own language first. The box at the top filters the whole list by name or abbreviation.

Each entry carries what you need to choose between them: the year, whether it is public domain, and a warning where the coverage is partial — New Testament only, Old Testament only, or partial. Already-installed entries show a check and the date you installed them.

02

Install a translation

Click Install next to any direct-download entry. The progress bar shows download, parsing, and storage phases. Most installs take a few seconds. If one fails, the entry offers Retry rather than losing your place.

JW.org editions are not downloaded by this app. They open the publisher's own page, where you download the EPUB and then drop it into the import zone here. Before that link opens you are asked to accept their terms of use once — and because the acceptance is recorded against a person rather than a browser, that step needs you signed in. Importing a file you already have never requires an account. What you may do with content you bring in yourself is set out under Content & Copyright.

What that dialog says about your file is worth reading rather than clicking past. The EPUB itself never leaves your device — it is not uploaded and no copy is kept. But paragraphs you write a comment on are saved privately to your account, readable only by you, which is how your work reaches your other devices. That is a different promise from “none of it is stored”, and it is the one the dialog now makes.

03

Or drag-and-drop a file

You can also import Bible files directly: EPUB, MySword (.mybible), e-Sword (.bblx, .bbli), JSON, or a SQLite Bible database (.sqlite, .db). Drop the file on the import zone and it auto-detects the format. There is a second drop zone on the Bibles page itself, behind Add Bible File.

Have none of those to hand? Both drop zones offer a complete King James Version packaged as a genuine e-Sword .bblx module — one click imports it, which is the quickest way to see what an app-format import actually does. The catalog lists it alongside the sites where e-Sword and MySword modules are published, if you want to go looking for more.

Browsing & reading

Go to Bibles to see your installed translations. The whole canon is listed further down that page as two grids, Old Testament and New Testament — tap any book to open its first chapter. The Browse button on a translation card is a shortcut that drops you at Genesis 1.

Once you are in a chapter, the book and chapter title in the breadcrumb is a button: tap it to open the navigator and jump to any book, or to any chapter of the book you are in. The Prev/Next buttons at the foot of the page move one chapter at a time and roll over into the next or previous book at the ends, so you can read straight through.

Switching translations is the dropdown at the top right of a chapter. Your choice is remembered and used the next time you open any chapter. Note that Browse does not switch to the translation whose card you tapped — use the dropdown once you are there.

When a chapter comes up empty

You will occasionally open a chapter and be told No verses found for Genesis 1 in WEBNT. That is almost always coverage rather than a fault: plenty of catalog entries are New Testament only, and a few are Old Testament only or partial. The book you asked for is simply not in the translation you are reading.

Switch translations with the dropdown and the chapter appears. The catalog labels coverage on every entry, so you can see which of your Bibles are complete before you install them.

Keyboard shortcut: Press C on any chapter page to enter verse selection mode. Press A to select all verses. Press Esc to exit selection. Once in selection mode, Shift+Click selects a range; on a touch screen, press and hold the first verse and then tap the last.

Searching Scripture

Bible Search has grown into several different ways to find a verse, and they answer genuinely different questions:

  • Reference lookup — type "Heb 6:10", "he6.10", or "Hebreos 6:10" and get the passage from every translation you have installed. English and Spanish are both recognised automatically.
  • Keyword search — type words to search every installed Bible at once. Forgiving about spelling in longer words; quote a phrase for an exact match; filter the results by translation. Put a reference in front of the words — romans 3 faith — to search inside just that passage.
  • Words together — with two or more words typed, chips let you look for them in the same verse, within a few verses, or in the same chapter. Results come back as continuous passages rather than lone verses, because two ideas argued across four verses are one answer, not two.
  • Boolean operatorsOR for either word, NOT to exclude one, brackets to group. Capitals are required, which is what keeps a Spanish no from turning a search into its opposite.
  • Pattern search — find every form of a word at once, or verses with a structural property such as ending in a question mark.
  • Strong’s search — search the Hebrew and Greek behind the translation. It works in every Bible you have installed, including untagged and Spanish ones, because it never looks at their wording.

Any of these can be narrowed to part of the Bible — the Gospels, the Prophets, a single book — and a strip under the results shows where your matches actually fall across Scripture. Search something in the Gospels and find nothing, and it tells you how many verses are elsewhere rather than leaving you to conclude the word is absent.

There is also an Ask box that turns a plain-language description into a query you can read and edit — without ever letting a model quote Scripture or hand you a citation.

Full walkthrough: Bible Search covers every one of them, with examples, the options that matter, and what each one deliberately will not do.

Both search boxes remember what you did. The one on the Bibles page keeps your recent lookups as chips underneath it. The one on the search page keeps your last twelve searches in a drop-down panel — complete with the part of the Bible each was narrowed to and how many results it found — so picking one restores the whole search rather than just the words.

The concordance

Bibles → Concordance counts instead of listing: how often a word appears in each translation you have installed, and whether they disagree about it. It reports occurrences the way a printed concordance does — a verse using the word twice counts twice — alongside the verse count the search page uses.

A translation with no search index yet is marked not counted rather than shown as zero, since zero would claim the word is missing from a Bible nothing actually read. The Bible Search guide covers it in full.

Parallel verse comparison

Click any verse number in the chapter view to open the parallel comparison panel. This shows the same verse across every installed translation, grouped by language (English versions together, Spanish versions together).

This is useful for spotting nuances in translation — how different Bibles render key words or phrases. Click the same verse number again to close the panel.

Where two of your translations are in the same language, a Differences toggle marks the words that actually differ between them, so you are not comparing by eye. It is offered only within a language: marking an English verse against a Spanish one would highlight every word and mean nothing. Punctuation and capitals are ignored when matching, and the text shown is always the original.

The verse page

Every result in a keyword search links through to a page of its own, at a URL like /bibles/john/3/16. It is the same idea as the comparison panel with more room: one card per installed translation, grouped by language, with the reference and a translation count at the top.

  • Copy on any card puts that verse on your clipboard already formatted — John 3:16 (ASV) on the first line, the text in quotes underneath. This is the quickest way to get a verse into a comment you are drafting elsewhere.
  • Previous / next verse step through the chapter one verse at a time, keeping every translation in view.
  • View full chapter returns you to the chapter in your preferred translation.
  • Arriving from a search, your search terms stay highlighted in every translation, and a Back to search link returns you to the results you left.
This page always shows every translation you have installed, regardless of which one you were reading. It is the one place where the answer to “how does my other Bible word this?” is already on screen without asking.

Commenting on verses

01

Select verses

Press C to enter selection mode, or tap the Comment button. Click or tap verses to toggle them. For a range, use Shift+Click — or on a phone, press and hold the first verse and then tap the last. The selection bar at the bottom shows how many verses are selected.

02

Click "Comment"

The comment overlay opens with the selected verses shown as a read-only source panel. Write your comment in the text area below. If you have bilingual mode enabled, you'll see both an English and Spanish text area.

03

Add tags and save

Add tags to organize your comments by topic (type and press Enter or comma). Click Save. Your comment is saved to a subject named after the book and chapter (e.g., "Hebrews 6"), created automatically if it doesn't exist.

04

Get coaching

After saving, you can coach your comment from the dashboard like any other entry. The coaching evaluates clarity, depth, and relevance against the source passage.

Alternative: Compose-then-cite

You can also start from the Compose Form on your dashboard:

  1. Click Add Scripture in the compose form
  2. The BiblePicker opens — select Version → Book → Chapter → Verses
  3. The selected verse text auto-fills the source field, and the reference auto-populates the subject name
  4. Write your comment and save

Managing your Bible library

  • Add Bible File — the Bibles page has its own drop zone, so you do not have to go through the catalog to import a file you already have. It takes EPUB, MySword (.mybible), e-Sword (.bblx, .bbli), plain JSON, and SQLite Bible databases (.sqlite, .db), and detects which it got from the file itself.
  • Export Library — downloads every installed Bible as one JSON backup file.
  • Restore Library — re-imports from that file. Anything already installed is skipped rather than duplicated, and you get a summary of what was restored, skipped, and failed.
  • Update detection — installed JW.org Bibles are checked against the publisher's current file in the background, and show an Update button when theirs has changed.
A backup does not carry copyrighted Bibles. Public-domain translations travel in the file; licensed ones are recorded by name only. On restore they are listed under These copyrighted Bibles need to be re-imported from their original source, each with a link back to where you got it. The catalog tags them needs re-import too, so a half-restored library tells you what is missing instead of looking complete.

Storage, and keeping it

Under your installed Bibles is a line reporting what the library actually costs on this device — not an estimate. It reads something like:

3 translations using 14.2 MB · room for about 40 more · 4.1 MB text, 10.1 MB search data

Underneath, each translation is broken out into text, index (what keyword search needs) and patterns (what pattern search needs, if you have enabled it). The split is shown because search data usually dwarfs the text it indexes, and it is worth knowing which part of the figure is the Bible and which part is the searching.

“Not yet saved for offline use” is the one warning to act on. Browsers may evict storage from sites they consider disposable, and until your library is marked as persistent it is eligible. Installing this app to your home screen, or simply using it regularly, is what convinces the browser to keep it. Until that message disappears, treat Export Library as your real backup. See Install on iPhone and Library Transfer.

Tips

  • Install both an English and a Spanish Bible for bilingual verse comparison
  • Use citation shortcuts: "ge1" for Genesis 1, "re21.4" for Revelation 21:4
  • When a study question turns on a word choice, Strong’s search settles it — it tells you whether two verses really use the same original word
  • Your preferred Bible version is remembered between sessions, as is the last chapter you read
  • All Bible data works offline — no internet needed to read, search, or comment
  • Verse comments auto-group into subjects by chapter, so your insights stay organized
  • Need a verse in a hurry? Open the verse page and use Copy — it arrives already formatted with the reference and translation
  • If the storage line on Bibles says not yet saved for offline use, export a backup before you rely on the library

FAQ

Where is my Bible data stored?

In your browser's IndexedDB, locally on your device. Nothing is uploaded to the server. If you clear browser data, you'll need to re-install or restore from a backup.

Browsers can also evict storage on their own when space runs short. The Bibles page tells you whether yours is protected yet — if it says not yet saved for offline use, keep an exported backup until it does.

Can I use any Bible translation?

The catalog includes 168+ translations. You can also import any Bible you already have in EPUB, MySword (.mybible), e-Sword (.bblx, .bbli), JSON, or SQLite format by dragging it onto the import zone — no account needed.

How does verse selection work on mobile?

Tap the Comment button at the bottom right to enter selection mode, then tap verses to toggle them one at a time. The selection bar appears at the foot of the screen with a count, All, Clear, and Comment.

For a range, press and hold the first verse, then tap the last one. The held verse starts pulsing and the bar reads From 12 — tap another verse, so you can see what the next tap will measure from. Tapping the held verse again cancels the range and leaves it selected. On a keyboard the same thing is Shift+Click.

Can I move my Bible library to another device?

Yes. Use Export Library to download a JSON backup, then Restore Library on the new device. See the Library Transfer guide for full instructions.
