Lamplighter
Your light for the Word
A cross-platform Bible reader designed for serious study. Lamplighter keeps everything local - your reading progress, highlights, and notes never leave your device. No accounts, no cloud sync, no tracking.
Why Lamplighter is Different
Plain JSON Format
Bible versions are stored in simple, human-readable JSON files. No proprietary formats, no special tools needed. Anyone can create new translations, study resources, or custom content using just a text editor.
100% Local Data
Your highlights, notes, bookmarks, and reading history stay on your device. No account required. No internet connection needed after initial download. Your Bible study is truly private.
Community Content
The JSON format makes it easy for anyone to contribute. Create your own Bible study resources, commentaries, or even new translations and share them with others.
Features
Reading Modes
Verse-by-verse or continuous reading. Dark mode for late-night study. Adjustable fonts and sizes.
Highlighting
Mark verses with multiple colors. All highlights saved locally and synced across your devices via file export.
Quick Navigation
Jump to any verse with natural references like "John 3:16" or "Gen 1". Book picker with smart search.
Study Panel
Side panel for cross-references, commentaries, and original language tools. Syncs with your reading position.
Multiple Versions
Load any Bible version in JSON format. Compare translations side-by-side. Add public domain versions easily.
Offline First
Works completely offline. All content cached locally. Perfect for areas with limited connectivity.
The JSON Format
Most Bible software uses proprietary formats that lock you in. Lamplighter uses plain JSON - a standard format that any developer (or curious non-developer) can work with.
Want to add a Bible version? Create a JSON file with books, chapters, and verses. Want to create a commentary? Same format. The schema is documented and simple.
This means the community can contribute without needing special tools or permission. Find a public domain Bible text? Convert it to JSON and use it in Lamplighter. Write your own study notes? Export them as JSON and share.
