Frequently asked questions
Is Live Transcribe + the same app as Google Live Transcribe?
No. Live Transcribe + is made by Zerovik, and its App Store listing says it is not associated with Google. Google's Live Transcribe is a free Android app, and the iPhone app called Live Transcribe is made by Mighty Fine Apps. Captio AI is another separate app, on iPhone and Android.
Does Live Transcribe + work without internet, for example on a flight?
Its App Store listing says it transcribes in real time even when offline; Zerovik doesn't list which of its 60+ languages work offline. Captio AI needs internet for live captions; without it, it keeps recording and transcribes when the phone is back online.
Is there a Live Transcribe + app for Android?
No Android version was found: a Google Play search finds no app by Zerovik, and the App Store lists Live Transcribe + for iPhone and iPad. Captio AI runs on iPhone, iPad and Android.
How much does Live Transcribe + cost in the US?
The first 5 transcriptions are free; after that it needs a monthly or yearly subscription. The US App Store lists "Full Access" purchases from US$3.99 to US$79.99 (October 2026) without saying which is which. Captio AI gives 100 free credits a day and 3 AI summaries in total; Captio AI Plus is US$14.99 a month or US$79.99 a year on the US App Store, with no free trial.
Can Live Transcribe + show who is speaking in a meeting or at a family dinner?
Zerovik's pages don't describe speaker labels or recognising voices for Live Transcribe +. Captio AI labels each speaker (Speaker 1, Speaker 2). With Recognize Voices (iPhone) it shows the names of people whose voices you saved instead, and with Speaker Direction (iPhone 16 and later) a wave shows which side of the table a voice comes from.
Can Live Transcribe + translate Spanish into English?
Its App Store listing doesn't mention translation, though a 2024 post on Zerovik's website describes voice translation; Zerovik also sells a separate translator app. Captio AI translates conversations live in 60+ languages and shows the translation next to the original captions.
Which one is better for a doctor's appointment?
If the clinic has no signal, Live Transcribe + says it works offline. Captio AI needs internet for live captions, but lets you add names and medical terms so they are recognised, keeps the recording, and can turn it into a summary or to-dos.
Does either app caption phone calls?
Neither is described for phone calls. Zerovik's listing describes speech picked up by the phone's mic or a Bluetooth device. Captio AI is made for speech in the room around you, not for calls.
