InSpiritInTruth
A devotional app that writes a devotional for what you're going through and checks every scripture reference. 131 active users and a 5.0 App Store rating.
Made for people at every stage of faith. It keeps the shared daily readings and adds personal devotionals.
Why it exists
Barna found that 56% of Christians say their spiritual life is entirely private, yet devotionals are written the same for everyone. ISIT includes the shared readings and the Bible, and writes a devotional for each person's situation.
Checking every devotional
Every devotional is fact-checked against live web search before anyone reads it. I tested a cheaper model twice and rejected it both times.
Where the AI effort goes
Most of ISIT's AI processing goes into checking the generated text rather than writing it.
| Stage | Share of effort | What changed |
|---|---|---|
| Writing | ~22% | The devotional itself, drafted from what you shared. |
| Verifying | ~77% | Live web-search fact-checking of every claim, before a reader ever sees it. |
| Reflecting | ~1% | The closing reflection pass. |
Verification is the one cost I won't reduce to improve margins.
Early signal
It's early, and the main question is whether people want a devotional written for them.
