Your AI Chief of Staff — a personal operating system starter kit that adapts to your role. No coding required.

What it solves

Dex is a personal operating system for work management designed for non-technical professionals. It streamlines strategic work, meeting intelligence, relationship tracking, and daily planning by integrating various data sources (like calendars, Slack, and Salesforce) into a unified AI-driven workflow.

How it works

Dex functions as a "vault" of Markdown files (notes, projects, people, and tasks) and a set of tools that can be used by different AI "harnesses" (such as Cursor or Claude Code). It utilizes the Model Context Protocol (MCP) to sync tasks across files automatically and integrates with local system apps (like Apple Calendar on Mac) to provide context-aware planning.

Who it’s for

Non-engineers and professionals who want an AI-powered chief of staff to manage their professional life without needing to write code.

Highlights

  • Multi-tier capability system: Supports different levels of AI integration, from simple Markdown files (Tier 0) to full automatic in-chat behaviors (Tier 3).
  • Automated daily planning: The /daily-plan command scans calendars and goals to protect focus time and organize the day.
  • Cross-file task synchronization: Checking off a task in a meeting note automatically updates it in project files and person pages via MCP servers.
  • Role-based configuration: The system configures itself around the user's specific professional role after a simple /setup command.
  • Self-diagnostic tools: Includes /dex-doctor for system health checks and automated bug reporting.

    asheshgoplani/agent-deck

    Agent Deck is a Go‑written terminal UI that lets you launch, monitor, fork, and orchestrate multiple AI coding agents (Claude, OpenCode, Codex, Pi, …) from a single pane. It adds group‑based policies, per‑group Claude credentials, MCP tool toggles, cost dashboards, git‑worktree handling, and a phone‑controlled *conductor* that can be queried via Telegram/Slack/Discord. Install with a one‑liner script, Homebrew, or `go install`, then manage sessions with keyboard shortcuts (`Enter` to attach, `f` to fork, `$` for cost, `/` to search, etc.).
