Questions people ask
01Is there a limit on recording length?
No. Transcription finishes on your device, so it costs us nothing and there is no reason to sell it by the minute. Record for as long as your storage allows.
02Does my audio go to a server?
It does not. Audio files stay on your device and we cannot read them. When you request an AI summary the transcribed text passes through a server, but the audio itself never does. The full flow is listed in the privacy policy.
03Does it work offline?
Recording and transcription work in airplane mode. AI summaries and the ads in the free version need a connection.
04Which languages does it understand?
Korean first, with the model bundled in the app so there is nothing to download. English, Japanese and Chinese are in preparation; choosing one of those will download its model.
05How do I know if the summary is wrong?
Each line carries the time it came from. Tap it and playback jumps there — three seconds to check. Lines the model could not ground carry no timestamp at all, which is itself a signal.
06Can I transcribe recordings I already have?
Yes. Files recorded by other apps, your device’s voice recorder, and call recordings all show up grouped by folder. Pick one and it becomes text just like something you recorded here. Voice messages from KakaoTalk or Telegram work too — just use the share button.
07Does importing a file store it twice?
No. Files already on your device stay where they are; the app references them. A 90-minute recording is 43 MB, and copying it would double the space for nothing. If you delete the original, playback stops but the text and summary remain.
08Can I speed up or slow down playback?
Six steps from 0.5x to 2x. Reviewing a lecture you already attended goes well at 1.5x; a passage you cannot make out goes better at 0.7x. The transcript scrolls along as it plays, so you can see where you are.
09Can I fix a word the app got wrong?
Long-press any line in the transcript to edit it. Proper nouns and jargon are where an on-device model most often slips. Fixing one line is far quicker than rewriting the whole thing.
10Can it record phone calls?
No. Call recording is not supported. An incoming call pauses the recording, which resumes when the call ends.
11May I record other people?
Laws differ by country, and recording a conversation you are not part of is a criminal matter in many places, including Korea. The app cannot make that judgement for you, so the terms set out where the responsibility lies. Please check before you record.
12How does this relate to Snapuno and PDFMon?
Sibling apps from the same company (BUKCS PTE. LTD.). PDFMon opens and reads documents already on your device, Snapuno brings what is on paper onto it, and Voiceuno keeps what was said.
