Search.
Understand.
Reflect.
A privacy-first, offline Islamic research app. Native SQLite FTS5 search over the Qur'an and hadith — grounded by data, not generated by AI.
Designed for clarity. Built for reliability.
A small number of things, done with care. No feeds, no notifications, no cloud.
Offline-first
Works without internet after setup. Runs on low-end Android devices — no background sync, no updates required.
Instant search
Native SQLite FTS5 full-text search across Qur'an and hadith, in English and Bengali. Results appear as you type.
Authentic data
Built on the Qur'an and hadith with full references — surah, ayah, book, and number on every result.
Private by design
No external APIs. No tracking. No cloud. Your reading stays on your device, always.
Search. Retrieve. Explain.
A strict retrieval-first pipeline. The AI never generates facts — it only summarizes what the database returns. No hallucinations. No generated facts.
Search
Queries hit a native SQLite FTS5 index on-device. Arabic, English, and Bengali — instant, even on older phones.
Retrieve
Matching verses and hadith are pulled from the local corpus, with surah, book, and number intact. No network request leaves the device.
Explain
A local model summarizes only the retrieved passages. If the sources are silent, Hujjah says so.
No hallucinations. No generated facts. The AI never introduces information outside of what the local database returns.
A deeper library, on the device.
Three tools that work without an account, without a connection, and without sending anything anywhere.
Hadith database
The Kutub al-Sittah — six canonical collections — browsable and searchable offline, with grade, narrator, and book references.
Sanad chain explorer
Walk the isnād of any hadith — every narrator, every link in the chain, laid out as a readable tree.
Offline AI explanations
A small on-device model. It paraphrases retrieved passages — never invents them. Runs with no network, no account, no keys.
Quiet on the eyes. Clear on the mind.
Three moments from the app — the same typographic restraint you see here, on a smaller screen.
A tool you can trust
because nothing leaves.
Hujjah is built by engineers who care about correctness. A research tool for sacred text should not be a surveillance product.
-
01
Works offline
Once installed, Hujjah runs entirely on your device. No connection required, ever.
-
02
No external APIs
Search, retrieval, and explanation all happen locally. There is no server to call.
-
03
Your data stays on your device
No accounts. No telemetry. No backups we can read. The app doesn't know who you are.
-
04
Built for accuracy, not speculation
Explanations are anchored to the text they cite. When the sources are silent, Hujjah says so.
Coming soon, everywhere you read.
Hujjah is built once and shipping across Android, iOS, macOS, and Windows. A small, independent project — released slowly, tested carefully, made to last.
One build. One release. Notified the moment it ships.
