Navgar Chat now has voice memo and transcriptions with both the sender and the receiver in mind and can be used in any chat context, including your own chat tasks!
For the sender: You will notice the microphone icon on the right side of the chat entry field, which allows you to record your memos to your conversation participants. Unload your mind and then save the recording prior to sending it.
For the receiver: The audio will almost instantly appear in the chat it was sent in, but you will want to wait a moment for transcription to complete, especially for those long ones ;)
