The Bottom Line

Enterprise AI tools are built to serve the organization. Copilot is woven across Microsoft 365 — Outlook, Word, Excel, Teams — and it's genuinely capable across all of them. In Outlook specifically, it drafts and summarizes when you prompt it. It requires an M365 subscription plus the Copilot add-on at around $30/user/month. For teams already deep in Microsoft's stack, that often makes sense.

What it doesn't do is run automatically. Copilot responds to prompts. Your inbox doesn't get handled while you're in a meeting. The labels don't apply themselves. The follow-ups don't surface on their own. You still have to be there.

Clarity is built around a different idea: your inbox should work even when you're not in it. Inside Gmail or Outlook, it labels every email by urgency and intent, drafts replies in your voice, tracks every sent email for follow-ups, and sends a morning brief. No prompting. No clicking. You check in when you're ready, and the work is already done.

If Copilot is already in your M365 contract, it covers email among many things. If you want your inbox to run on autopilot and a free plan to start, Clarity is built for exactly that.
