Category comparison
Section titled “Category comparison”Speed & polish
Section titled “Speed & polish”Superhuman has built its brand on being the fastest email experience available. Every interaction is optimized, search returns results instantly, emails load before you click them, and keyboard shortcuts cover every action. The onboarding includes a personal session to teach you their workflow. The attention to detail in the UI is exceptional.
Maho Mail is fast because it is local, search runs against a SQLite database on your machine, and there are no network round-trips for cached data. But the GUI is more functional than luxurious. Maho invests its design budget in the three-interface architecture rather than micro-interactions. If raw UI polish is your priority, Superhuman is ahead.
Automation & programmability
Section titled “Automation & programmability”Superhuman offers workflow features, snippets, scheduled sends, reminders, split inbox, but all of them live within the GUI. There is no CLI, no API, and no way for external tools to access your email programmatically. Automation means using Superhuman’s built-in features.
Maho Mail treats email as programmable data. The CLI gives you maho search --from alice --after 2026-01-01 --json and pipes the result into jq, Python, or any other tool. The MCP server lets AI agents handle your inbox. You can build workflows that Superhuman’s GUI simply cannot express.
AI approach
Section titled “AI approach”Superhuman has its own AI features, auto-triage that sorts email into categories, AI-powered draft suggestions, and thread summaries. These are polished and integrated into the workflow, but they use Superhuman’s chosen models and run on their infrastructure. You cannot swap providers or customize behavior.
Maho Mail lets you bring your own AI provider, OpenAI, Anthropic, or Ollama for fully local inference. Beyond built-in features, the MCP server means any AI tool can interact with your inbox. The difference is control: Superhuman gives you curated AI. Maho gives you programmable AI.
Privacy & cost
Section titled “Privacy & cost”Superhuman is a cloud service at $30 per user per month ($360/year). Your email data flows through their servers. For teams, the cost scales linearly. Superhuman’s business model depends on this subscription revenue, and the service requires an active subscription to function.
Maho Mail is free, forever. All data stays on your machine. There is no subscription, no cloud dependency, and no telemetry. If cost or data sovereignty matters, this is a significant difference. The tradeoff is that Maho does not have Superhuman’s team features, support infrastructure, or design resources.
Team features
Section titled “Team features”Superhuman has invested heavily in team email, shared labels, team analytics, management dashboards, and onboarding for organizations. Maho Mail is built for individual users and does not have team collaboration features. If you are evaluating email for a team, Superhuman is designed for that use case.
