Superhuman is a premium, keyboard-first email client built for speed — split inbox, read statuses, auto drafts, and AI writing tuned for people who live in email ($30+/month). AI42 takes a different angle: email is one channel inside an AI command center with persistent memory that executes work across tasks, cited research, meeting transcription, and finance — not only mail. Choose Superhuman if you want the fastest dedicated inbox experience; choose AI42 if you want an assistant that remembers your full work context and acts beyond email.

Superhuman optimizes how fast you process email. AI42 connects email to the rest of your work — tasks, research, meetings, and finance — with memory that carries context forward.
Chat, voice, research, and meeting summaries draw from a single AI Power budget instead of paying for a premium inbox plus separate tools.
AI42 remembers projects, preferences, and history across conversations — not only what's in today's thread.
