MailCopilot vs Superhuman
Superhuman made keyboard-speed email famous and now leads with AI features — as a paid, cloud-based service on top of Gmail and Outlook. MailCopilot takes the opposite architecture: a free, open-source desktop client where mail stays on your machine and AI runs under your own key. Which trade-off fits you?
| Feature | MailCopilot | Superhuman |
|---|---|---|
| Price | Free | Paid subscription |
| Open source | Yes — AGPL-3.0 | No |
| Works with | Any IMAP/SMTP provider + Gmail/Outlook OAuth | Gmail and Outlook only |
| Where your mail lives | Locally, on your machine | Processed in Superhuman's cloud |
| Built-in AI assistant | Built-in: GTD triage, smart replies, thread summaries — with your own API key (Claude, OpenAI-compatible, Gemini) or a local model like Ollama | Auto Drafts, Auto Labels, Ask AI (vendor-managed) |
| AI data control | Your key or a local model; AI can't send or delete without your confirmation | Vendor-managed |
| Agent integrations (MCP) | Yes — client and server | No (proprietary browser agent) |
| Platforms | Linux, Windows, macOS (native desktop) | macOS, iOS, Android, web |
| Keyboard-first triage | Gmail-style keys, command palette | Yes — its signature strength |
| Snooze & follow-up reminders | Built-in | Built-in |
| Offline mode | Yes — per-folder sync | Partial |
| Tracking pixel blocking | Yes, by default | Read statuses are a core feature |
Choose Superhuman if…
- You want a polished, managed service and don't mind the subscription
- You need first-class iOS/Android apps today
- Your team already runs on Gmail/Outlook and wants shared team features
Choose MailCopilot if…
- You want your mail processed locally, not in someone's cloud
- You use Linux or Windows and want a native desktop client
- You want AI with your own key — or a local model — instead of a bundled black box
- You want Superhuman-style speed without the price tag
