FAQ
Reader questions
Can the app translate voice messages without internet?
Yes, if the language pair is downloaded for offline use, short voice messages can be processed entirely on device with reduced accuracy for very complex phrases.
How does the app handle overlapping speech in meetings?
Speaker diarization and voice separation algorithms identify who spoke when, but overlapping talk may still cause fragmented or reordered segments in the transcript.
Are my conversations stored on external servers?
By default, anonymous usage metrics may be sent to improve models, while transcribed audio can stay on device unless the user explicitly opts into cloud backup with encryption.
Do professional plans include industry-specific terminology?
Professional tiers often provide customizable glossaries and domain packs for legal, medical, and technical fields, allowing teams to maintain consistent vocabulary across documents.
