diio analyzes the content of what each person says during the conversation and assigns an overall mood: Happy, Neutral, or Angry. This allows quickly identifying the counterpart's emotional state without having to listen to or read the entire transcript.

Each participant's mood is shown in the Participants section of the top block in the detail view. It appears next to the person's name, their role (Counterpart or Executive), and their percentage of participation in the conversation.

Happy. The person showed a positive tone during the conversation: enthusiasm, agreement, openness.

Neutral. The person maintained an informative or moderate tone, without clear positive or negative signals.

Angry. The person showed frustration, rejection, or discomfort at some point during the conversation.

diio analyzes the language used by each participant throughout the entire conversation. It is not based on tone of voice, but on the content of what is said: words, phrases, expressions, and context. The assigned mood is the predominant one during the conversation, not that of a specific moment.

In sales: if the prospect ended with an Angry or Neutral mood despite positive progress, it is a signal to adjust the approach in the follow-up.

In recruiting: a candidate with a Happy mood throughout the interview usually shows greater real interest in the process.

In customer support: conversations with Angry mood are the first to review to identify experience issues.

In internal coordination: if several participants from a team meeting ended with Neutral mood, it may indicate a lack of clarity in the agreements.
