diio analyzes the content of the conversation and assigns it an overall mood: Happy, Neutral, or Angry. This lets you quickly identify the counterpart's emotional state without having to listen to or read the entire transcript.

Mood is a single value per conversation (not one per participant) and is shown in the Participants section of the top block in the detail view, only next to the counterparts. It appears next to the person's name, their role, 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 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's a signal to adjust your approach in the follow-up.

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

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

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