Cheqer
See a word. Search it out.
Cheqer (חֵקֶר, pronounced KHAY-ker) is the Hebrew word for a searching out: a deep inquiry into a matter. The app is built around that one move. Read the Bible in English with the Hebrew or Greek underneath, tap any word, and see the original word behind it: its root, its meaning, how to say it, and every place it appears in Scripture. Then ask the text your questions in plain English and get answers that show their work.
“It is the glory of God to conceal a matter, but the glory of kings is to search out a matter.”
— Proverbs 25:2, the verse Cheqer is named for
How to Cheqer
Everything grows from one tap
📖 Read
English on top, the original underneath
The Reader shows the English text with the Hebrew or Greek beneath it. Pick any book, chapter, or verse, or type a reference like John 3:16 straight in. Switch between the BSB, KJV, and WEB translations, or hide the original line when you just want to read.
🔍 Search out a word
Tap a word, meet the original
Tap any English word and a sheet shows the Hebrew or Greek behind it: root, meaning, and a 🔊 button that says it aloud, syllable by syllable. Tap the original word to open the full Word Study: how translators render it, how its meaning moves across the eras of the canon, how the Septuagint carried it into Greek, and every occurrence in Scripture.
💬 Ask
Plain-English questions, answers from the text
Tap a verse and ask what it is really saying, what its themes are, how it connects with the rest of Scripture. Grow the selection into a passage first if you like. The Ask ✨ button takes wider questions, like where does Scripture talk about the sons of God?, and comes back with the verses found and the original words behind them.
🏛️ The Library
The world Scripture was read in
Josephus, Philo, 1 Enoch, Jubilees, and more, readable in English. Not Scripture, but the writings from the centuries around the New Testament that show how its first readers thought.
✍️ Studies
Keep what you find, share what's best
Save word studies and Ask answers as notes with a free account. Keep them private, share them with your study group, or publish your best ones for everyone using Cheqer, and save a copy of any community study to build on it yourself.
🔊 Hear it
Hebrew and Greek, spoken
Every pronunciation guide reads the word aloud using the voices on your device. Phones usually sound natural; on a computer, Edge and Chrome carry the best built-in voices and the app picks the most natural one it finds.
What makes it different
AI that shows its receipts
Most AI Bible tools hand you a confident paragraph and ask you to trust it. Cheqer was built by an AI researcher who knows exactly how these systems go wrong, so it is designed around one rule: nothing stands without a source you can check.
Searched, not invented
Every answer is searched from the text
When you ask a question, Cheqer does not guess. It searches the Scripture and the original-language data, then answers from what it found. Each answer carries a “How this was found” receipt showing the actual searches behind it, so you can see the path, not just the conclusion.
A citation for every claim
Word studies you can verify
Each Word Study includes a written brief tracing the word from the Torah through the prophets, and every claim in it carries a citation. If the brief says a word shifts meaning between two eras, it points you to where.
Sod · סוֹד
The oldest witnesses, weighed in the open
The panels marked Sod take their name from the Hebrew for close counsel: the circle where trusted friends speak plainly. They gather the oldest witnesses around a word: how the Greek Septuagint translated it centuries before the New Testament, how the Aramaic Targum carried it, how Jewish writers between the testaments used the idea. Each witness is labeled with how strong its evidence is. Not hidden knowledge, and not Scripture: the counsel of the oldest witnesses, gathered so you can weigh them yourself.
Built on real scholarship
Open, credited sources underneath it all
The original-language text and tagging come from Tyndale House, Cambridge and STEP Bible; the Septuagint from the CenterBLC edition; Targum and Second Temple texts via Sefaria; Josephus via the Perseus Digital Library; Philo via OpenGreekAndLatin. All openly licensed, all credited inside the app. The AI sits on top of that foundation; it does not replace it.
Why it's free
Free, and it stays free
Cheqer is free and always will be. The Word should not sit behind a paywall, and a study tool should not decide what you get to see based on what you pay. The app does have real costs to run, so if it has helped you search something out, a coffee goes a long way toward keeping the lights on for everyone.
Part of a bigger question
The same conviction as the book
Cheqer comes from the same place as Image in the Machine: the belief that a machine built well can help a person see more clearly, and a machine built carelessly can quietly replace seeing with trusting. Cheqer is built to do the first. It is powered by Ailura, ONSQ's AI platform, and it will be a study tool in the Ailura AI Academy curriculum, so students learn to search out the Word with the original languages in hand.
