Sunflower AI vs Voco

Three meters running at once, versus none

Sunflower AI's Basic tier caps hours at 7.5 a month, rooms at 1, and target languages at 5. A church with two Sunday services is already past 7.5 hours, and one room means you cannot translate the youth gathering happening at the same time. Voco caps none of these — hours, concurrent sessions and languages are all unmetered on every plan.

Overage that does not sting

Extra hours on Sunflower AI cost $40 each. A church that runs 20 hours in a month on the Basic tier is $90 plus 12.5 extra hours, which is a materially different bill from the headline price. Voco has no overage because it has no meter — a mission week costs the same as a quiet week.

The long tail of languages is included

Basic covers 5 target languages and Pro covers 10. Voco includes all 155+ on every plan. The languages that get cut when you are choosing five are always the smallest groups — the one Tigrinya family, the two Twi speakers — who are exactly the people with the fewest alternatives.

Scripture handled as scripture

Voco detects a spoken reference like John 3:16 and inserts the officially published translation in the target language rather than translating the preacher's English wording back out. Sunflower AI's custom vocabulary is strong on proper nouns but does not describe scripture-specific handling.

A full month free, with no card

One month of the Basic tier at no cost and no card is the most generous trial in this category by a distance — Voco offers seven days. That is long enough to run four Sundays, gather real feedback from the language group, and make a decision on evidence rather than a demo. If you are still deciding whether translation is worth doing at all, start there.

Uploaded scripts and custom vocabulary

Sunflower AI lets you upload scripts and define custom vocabulary ahead of a session. For a preacher working from a manuscript, priming the system with the actual text and the proper nouns in it is a meaningful accuracy advantage, and it goes further than a glossary alone.

Speech-to-speech output

Sunflower AI generates translated speech rather than relying on the listener's device. For congregants who would rather listen than read, that is a better delivery mechanism than Voco's phone text-to-speech.
