About Protos
Protos is a Bible study app that attaches historical context, published commentary and original-language definitions to the verse you are already reading.
Most people who stop reading the Bible do not stop because they lack discipline. They stop because they do not understand what they are reading, and nobody ever taught them how. Protos is built for that reader: a beginner moving toward leading a small group, rather than a scholar. It is not a research suite and it is not a devotional feed.
The app puts the missing context on the verse itself. Open a chapter and the historical setting of the book is there: who wrote it, when, and what they were dealing with. Tap a word and its Hebrew or Greek definition opens without leaving the passage. Tap a name and a dictionary entry explains who that was. The study questions change depending on whether you are reading a psalm, a letter or a narrative.
Every definition and note was written by a scholar and published in a reference work, credited on the page it appears on: Tyndale Open Study Notes and Jamieson-Fausset-Brown for the commentary, Tyndale House via STEPBible along with Hastings', Easton's and Smith's for the dictionary, and TBESH and Abbott-Smith for Hebrew and Greek. The same 1,129 dictionary entries and 66 book commentaries are readable free on the web, with no account.
Key features
- Every verse carries the historical setting of the book it sits in, so a reader knows who wrote it, when, and what they were dealing with.
- Commentary from Tyndale Open Study Notes and Jamieson-Fausset-Brown, and entity articles from Tyndale House, sit beside the text rather than in a separate app.
- Any word can be opened to its Hebrew or Greek definition without leaving the verse.
- A Bible dictionary of 1,129 entries covers the people, places and terms the text assumes you already know.
- Guided study questions adapt to the genre of what is being read, since a psalm and a letter are not read the same way.
- Nothing in the app is AI-generated: every definition and note names the published work it came from.

About the developer
Protos is built by Fabio Jonathan Arifin, a Portland Bible College graduate who has spent years teaching in local churches. "People don't give up on the Bible for lack of discipline. They give up because they don't understand what they read. So they skim past it and jump straight to what it means for them, before they have listened to what God is saying through the words, the story, and the voice of the writer. It happens so often that theology has a name for it: eisegesis." Protos is the answer to that. Every explanation you read was written by a scholar and published in a reference work, credited right on the page.
