What it does

- Reacts to Claude Code and Codex events in real-time (thinking, working, permission requests, compaction, errors, completions)
- 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)
- Auto-updates via Sparkle

Requirements

- macOS 15.0+ (Sequoia)
- MacBook with notch
- Claude Code and/or Codex installed

Install

1. [Download the latest DMG][dmg] (all versions are on the releases page)
2. Open the DMG and drag Notchi to Applications
3. Launch Notchi, it auto-installs Claude Code and Codex hooks on first launch (whichever are present)
4. If a macOS keychain popup appears asking for access (used for API usage stats), click Always Allow so it won't prompt again

5. *(Optional)* Click the notch to expand → open Settings → paste your Anthropic or OpenAI API key. This enables sentiment analysis of your prompts so the mascot reacts emotionally

6. Start using Claude Code or Codex and watch Notchi react
7. Track usage by clicking on the usage bar
