# Katecheo

> A free, offline-first web app that turns a Bible book, chapter and verses into rich text with a deep link to the user's Bible app. It also ships 160 themed collections (14 categories) and 34 reading plans of whole chapters.

Katecheo is a verse picker, not a Bible reader. Copy "João 3:16" / "John 3:16" / "Juan 3:16" already linked, and paste into Notes, WhatsApp or a document.

```
