## What is Plumbline?

READ SCRIPTURE. NOTICE MORE. LIVE IT OUT.
A quiet Bible study journal built around the SOAP method. Reflect on God's Word with thoughtful questions, not ready-made answers.

MAKE SCRIPTURE PERSONAL
Follow four simple steps: Scripture, Observation, Application, and Prayer. Write what stands out, choose one small step, and keep your reflections together.

A STUDY GUIDE THAT ASKS, NOT TELLS
Turn it on when you want it. Brief, passage-based questions help you think more deeply. The AI study guide works from the Bible text you are reading and points to Scripture references. AI responses can contain mistakes; always check them against Scripture. The guide does not replace your pastor or your church. Only the notes and questions you choose to share are sent for AI processing. Your prayers are never sent.

LISTEN TO THE WHOLE BIBLE
The complete Berean Standard Bible, narrated by Bob Souer. Listen to a full chapter or just the verses you are studying, at home, on a walk, or in the car. Free for everyone.

READ AND REMEMBER
• Read and search the Bible offline in BSB, KJV, or WEB.
• Keep your journal encrypted on your iPhone. No account required.
• Look back on your week and see what you hoped to put into practice.
• Share beautiful verse cards. Your notes and prayers stay private unless you choose to export them.
• Follow 47 daily Lent and Easter readings.
• Set gentle reminders that never show what you wrote.

START FREE
