CaptionKit vs Kaleo AI
The Kaleo AI alternative with audio in over 120 languages
Kaleo AI reads translations in the phone's built-in voice, inside its app. CaptionKit has natural voices that play straight from a QR code. It can put translations on your auditorium screens too.

Listen instead of read
Audio translation reads the sermon aloud in natural voices, so people listen through their own headphones. Tap any sentence to jump the audio there. On every plan, the free app can also read translations aloud in the phone's own voice.

Questions
Do listeners need an app to hear the translation?
Not with CaptionKit. With natural voices, people scan the QR code and listen in the browser. The free iOS and Android apps add the phone's own voice for every translation on any plan, and keep audio playing with the screen locked. Kaleo AI's spoken translation is only in its mobile apps.
How does the price compare?
For text, CaptionKit costs less: 10 hours with 4 languages is $30 a month, against $49 for Kaleo AI's Pro plan. Listening is covered on both: CaptionKit's free app reads every translation aloud in the phone's own voice, with natural voices as an optional add-on.
Can we show the translation on our screens?
Yes. CaptionKit gives every language lower-third and full-screen links for ProPresenter, OBS, vMix, FreeShow or Worship Extreme. We couldn't find a screen output in Kaleo AI's documentation.
What if our pastor switches between languages?
CaptionKit's Multilingual input detects the language as it's spoken, so a sermon that moves between English and Spanish, or Korean and English, keeps translating with nothing to change. Kaleo AI doesn't say whether it follows a switch mid-service.
Is there a free trial?
Yes, 4 free hours with no credit card, the same length as Kaleo AI's trial, so you can run both on the same Sunday.
Made for church.
