Vision

Zayit is a dream turned useful: a natural, fluid, almost obvious study experience. The project will remain free by principle. Support is welcome and meaningful. It is designed to stay non-commercial. With God's help, Zayit will keep growing without losing its spirit.

In the spirit of a study hall

Zayit is designed like a digital study hall: stable, fast, consistent. You feel the calm of study: everything works, everything is in its place. The text stays at the center, with respect and without distractions.

A pro and natural interface

Zayit is built on JetBrains technologies, including Compose Desktop and Jewel. Inspired by Google Chrome and IntelliJ IDEA, it offers a professional interface that is fluid and natural, respects study, and does not strain the eyes. Zayit is easy to use: you already know how, no learning curve. Everything feels natural, intuitive, and within reach.

Modular panels

The layout adapts instantly: organize the screen the way you want. Show, hide, compare, and tailor reading to your study style.

An exceptional search engine

A powerful engine designed to understand texts, not just find them. The database was rebuilt to make search and navigation precise. Every result helps you move forward on the topic, without wasting time. Powered by Lucene and enhanced by AI for precision. It is likely the most powerful engine ever built for this kind of study. It finds words, forms, and variants with remarkable reliability. Search is fast, stable, and guides you straight to the right source.

Find a passage even from a partial word or approximate spelling.
Even without vocalization or cantillation marks, search stays clear and reliable.
A partial phrase is often enough to reach the right place.
Clean, readable, immediate results, useful for review and lesson prep.

Simple to go fast, advanced to go far.

Simple search.

Advanced search.

Crafted with care

Zayit aims for quality and consistency: no gimmicks, no noise. Like a digital study desk, everything is there to move forward. Every detail is designed for natural, respectful study. Built to be fast, light, almost magical, it runs even on low-powered machines.

Contributing

Zayit welcomes contributions from the community: bug fixes and features listed in the roadmap.

Note: PRs introducing new features not listed in the roadmap will likely be declined.

Getting started

Clone the repository with submodules:

git clone --recurse-submodules https://github.com/kdroidFilter/Zayit.git

Important: You must use JetBrains Runtime 25 (JBR 25) as your JAVA_HOME.

Architecture guidelines

Project structure:

SeforimApp/ — Main desktop application (Compose Multiplatform)
SeforimLibrary/ — Composite build: core (domain models), dao (SQLDelight persistence), generator (data pipeline, JVM only)

Dependency injection (Metro):

Access the DI graph via LocalAppGraph.current
Use @AssistedInject + @AssistedFactory for ViewModels

Naming conventions:

*ViewModel for ViewModels
*View for UI components
*State for UI state data classes
*Event for user action types

Tab system:

Each screen must know its tabId
Use remember(appGraph, tabId) to create ViewModels
Use TabStateManager for tab-scoped state persistence

Source sets:

Shared code in commonMain
Platform-specific code in jvmMain
Platform types must not leak from jvmMain to commonMain

For detailed documentation, see CLAUDE.md and TAB_SYSTEM_README.md.

Roadmap 0.5.0

Navigation history
Personal notes on text (Google Docs-like annotations)
Fix P0 and P1 issues
New home page widgets (time since destruction of Beit HaMikdash, history)
Chrome-like bookmarks bar
Automatic updates (Chrome-like): silent download + installation on app close
