When spf.io may be the better fit
We'd rather you pick the right tool than the wrong one. spf.io could suit you better if:
- You want an operator to correct captions live, or to release a pre-translated sermon script line by line.
- You need professional human captioners or interpreters on call.
- You also translate slides, documents and polls in the same tool.

“A bilingual staff member gave it a test run and was surprised by how incredibly accurate the translation was. We announced it to the whole church and it was an immediate hit. Your service may have just single-handedly moved our Spanish-speaking ministry to the next level.”

Questions
Do we need someone to operate CaptionKit during the service?
No. Start the session and CaptionKit translates on its own until you stop it, or it stops itself after a stretch of silence. Keywords help it get your church's names and terms right without anyone editing live.
