What it does

• Analyzes prompt sentiment via Anthropic or OpenAI APIs to show emotions (happy, elated, sad, neutral, sob)
• Click to expand and see session time and usage quota
• Tracks daily cost and token usage over the last 30 days, per provider or combined
• Supports multiple concurrent sessions, each with its own mascot from the Claude or Codex sprite family
• Sound effects for events with support for importable custom sounds (optional, auto-muted when terminal is focused)
• Available in English, 日本語, 简体中文 / 繁體中文, 한국어, and Tiếng Việt (follows your system language)
