Yes, you can view the chat logs from each conversation in Voiceflow. These are referred to as "Transcripts".
Transcripts provide a turn-by-turn record of each user interaction, including the utterances they used and the intents they hit along the way. This feature is designed to give you and your team an understanding of where your assistant was successful in helping your users, and where it can be improved.
To access the Transcripts, navigate to the main left panel located next to the sidebar. Once in the Transcripts tab, you can click through all available transcripts for your assistant in the left-hand Conversations List.
You can also sort, organize, and filter all of your available transcripts by date (Time Range) and by Tags. This information can be added and adjusted at the transcript-level, using the right-hand Actions Menu.
Moreover, you can configure the type of data you'd like to view in testing such as Debug Messages and Intent confidence data. Using the ... menu above each transcript, you can choose to enable and disable these fields that you'd see in the Test Tool.
Remember, if you add an utterance to an intent, it is important to re-train your Assistant before testing again, to ensure it is trained with the new data.
