AgentPeek
Tran Huu Hoang
Mac menu-bar app that puts Claude Code and Codex into the Mac notch to watch sessions, answer prompts, track tokens, and manage local dev servers.
Key features
- Notch & Menu-bar Integration: Embeds live Claude Code and Codex sessions into the Mac notch and menu bar for immediate, always-available access without switching windows.
- Live Session Viewer: Displays real-time agent activity and conversation streams so users can watch multi-agent interactions as they occur and inspect agent behavior.
- Interactive Prompt Handling: Surfaces permission prompts and allows users to answer, approve, or modify prompts directly from the menu-bar interface to control agent inputs.
- Token Usage Tracking: Monitors and reports token consumption per session or agent, helping developers manage costs and debug token-related issues.
- Local Dev Server Management: Provides controls to start, stop, and monitor local development servers tied to agent workflows, streamlining local testing and iteration.
- Local-first Privacy Model: Designed to run locally on the user’s Mac to minimize external data exposure and give users control over where agent data is processed.
- Release Log & Versioning: Public release log (changelog) with incremental releases (0.1.x series) so users can track features, fixes, and updates over time.
- Multi-agent Visualization: Integrates with multi-agent setups (per GitHub repo) to visualize interactions across agents for debugging and analysis.
- Embed Claude Code and Codex sessions in the Mac notch and menu bar
- Live session replay and real-time visualization
- Permission prompts and response handling
- Token usage tracking and metrics
- Manage and monitor local development servers
- Local-first storage: session data stays on device
- Live visualization of Claude Code and Codex agent sessions in the Mac notch and menu bar
- Interactive permission prompts allowing users to answer agent prompts from the menu bar
- Token usage tracking and reporting for monitored agent sessions
- Management and monitoring of local development servers associated with agents
- Real-time dashboard for multi-agent orchestration and activity inspection
- Local-first architecture (runs on user's Mac rather than cloud-hosted by default)
- Distributed via a one-time license purchase
Best for
- Observing Multi-Agent Workflows: Watch real-time exchanges between agents to debug coordination issues or verify agent decision paths without opening developer consoles.
- Rapid Prompt Approval: Approve, modify, or answer permission prompts from the menu bar to speed up interactive sessions with Claude Code or Codex during development.
- Token Cost Monitoring: Track token usage during experiments to identify costly prompts or optimize prompt engineering for lower consumption.
- Local Development Management: Start and manage local dev servers used by agents directly from the app, simplifying local testing and iteration cycles.
- Desktop AI Command Center: Keep an always-on control surface for AI coding assistants (Claude Code, Codex) accessible from the Mac notch for quick coding help.
- Agent Behavior Auditing: Capture and inspect live session logs to audit agent outputs, confirm compliance with expected behavior, or reproduce bugs.
- Monitor and debug multi-agent interactions during local development
- Quickly view and respond to agent prompts from the Mac menu bar/notch
- Track token usage and costs while iterating on agents
- Run and control local dev servers for agent workflows
- Provide lightweight agent observability during demos or testing
- Monitor and debug multi-agent workflows spawned by Claude Code or Codex in real time
Quartz
datarockets
AI-native email client for Mac that sorts your inbox and drafts replies in your voice, running entirely on-device.
Key features
- On-Device AI: Inbox sorting and reply drafting run locally on Apple Silicon, so email is never sent to external AI providers.
- Importance-Based Triage: Auto-categorizes every message by importance you define and the system learns over time, surfacing what matters and collapsing FYI, Icebox, and Noise.
- Voice-Matched Drafts: Learns your writing style, sender relationship, and thread context to draft replies that sound like you rather than a template.
- Local Encryption: Mail is encrypted on your device with keys only you hold, and the company has no servers that can read it.
- Gmail Integration: Connects to Gmail accounts and has been independently audited under Google's Cloud Application Security Assessment.
Best for
- Inbox Overload: Professionals who get high message volume let Quartz triage by importance so they focus only on mail that needs attention.
- Privacy-Sensitive Email: Users who handle confidential correspondence keep AI processing fully on-device instead of uploading mail to cloud AI services.
- Faster Replies: Drafting routine responses in the user's own voice to cut time spent writing repetitive email.
