Basically, voice calls and video calls transcription in RingCentral is very native to the RC app. This means that if the feature is available for a RingCentral plan, users under the account can use it within the RC app. In addition, a user can manually download the call transcripts (and other AI analysis insights if available) from the RC app.

Currently, there is no API to access the live transcripts and call insights generated for the RC app users.
For now, only the RingSense service (required RingSense license), which provides post call transcripts and insights analysis is accessible via the RingSense API.
Is RingSense and RC App transcriptions not the same thing then?
Is RingSense and RC App transcriptions not the same thing then?
Yes, the AI assistant available via the RC app is a real time transcription and agent notes. RingSense is a different service which is a post-call (required the call to be recorded) insights analysis and the result also comes with the transcripts and other metrics.
