Ever sat in a church service where half the congregation couldn't understand the sermon? Spf.io (pronounced "spiffy-oh") is an all-in-one AI translation and accessibility platform built to break down language barriers in worship services, conferences, and everyday conversations.^1
Created by TheoTech, a company founded by Christopher Lim after experiencing firsthand how difficult it is for bilingual churches to communicate effectively each week, spf.io delivers real-time captions and translations in over 100 languages.^2 It works with platforms like Zoom, YouTube, StreamYard, and OBS, and supports in-person, online, and hybrid events. Attendees simply scan a QR code or visit a link on their phones to receive live captions and translated audio — no app download required.^1
Beyond live events, spf.io handles video and audio subtitling, document translation, slide translation, multilingual polls, and even real-time multilingual conversations through its Convo feature.^1 Churches can customize the AI to learn their vocabulary, and the platform offers both autopilot mode and supervised AI where a human editor reviews captions in real time for higher quality.^3
What makes spf.io stand out is its deep roots in ministry. TheoTech also runs Project Pentecost, a movement helping churches reflect the multilingual diversity of God's Kingdom, inspired by Revelation 7:9.^4 The platform has partnered with Christianity Today Indonesia to accelerate Bible commentary translation and worked with the Theology of Work Project on custom biblical machine translation models.^5
Why Christians Love It"This is the first time I felt included." — A non-English-speaking attendee at One Voice Fellowship, after her first service with spf.io translation^3
"Before we could only have two languages broadcast at a time, now it is over 60 languages. Before, you needed a human translator per language group, but now you need one operator for 60 languages." — Briana Southerland, Share Ministries Pastor at First Alliance Church, Calgary^3
"With the spf.io Convo app, now we're able to have multiple people on a call in a group setting where we're speaking different languages, even more than two, and we're able to actually share our experiences, faith, and cultural expressions with one another." — Pastor Steven Zapolski, Founder of United Community Church^1
