AI for Church Hackathon 2026 · Building Oct 30 to Nov 27

Canticle.
Words that follow
the song.

Lyrics light up word by word, in time with the music.
No slide operator. No clicking through verses.

Not yet released.

Why it exists

For the church
with no media team.

Small churches do not always have a reliable
volunteer to run slides on Sunday.

Canticle presents lyrics full screen, or to a projector window, and keeps them in step with the song. It also shows the key and tempo for the people leading worship, so the room can stay together without someone driving the display.
