What to Look for When Choosing an AI Executive Assistant?
- Action over Answers: In 2026, the best tools are “Agentic.” They don’t just draft an email; they send it. They don’t just suggest a meeting; they find the time and send the invite.
- Deep Integration: Ensure the tool has native connectors for your specific “stack” (Gmail vs. Outlook, or Slack vs. Teams). Without deep access, the AI is just a chatbot, not an assistant.
- Context Memory: Look for “Long-Term Memory” features. Your assistant should remember that you hate Monday morning meetings or that you prefer specific vendors.
- Privacy & Governance: Verify the tool has SOC 2 compliance or enterprise-grade encryption. Since these assistants read your private emails and calendars, data safety is non-negotiable.
- Proactive Thinking: Choose a tool that offers “Inbox Triage” or “Daily Briefings.” A great AIアシスタント alerts you to problems before you even open your laptop.
- スケーラビリティ: Pick a tool that can grow. Some assistants are great for individuals, but others (like Atera) are built to handle the technical operations of an entire team.
