Inboxer vs Superhuman
Superhuman offers both a dedicated high-speed email client and an Email Assistant that runs directly inside Gmail or Outlook. Inboxer differentiates through source-linked commitments, multi-inbox workflow, meeting continuity, and one approval layer across email and meeting-derived actions.

The honest version
Superhuman ships two products: its original standalone, AI-native email client - you read and send mail inside it, not inside Gmail's or Outlook's own interface - and, more recently, Email Assistant, which brings Auto Labels, Auto Archive, Auto Drafts, and Auto Reminders directly into your existing Gmail or Outlook inbox, no separate app or extension required. Ask AI (a natural-language assistant that searches your inbox, calendar, and the web) and Custom Auto Labels remain tied to the Business tier of the standalone client; Auto Archive and Auto Summarize are on the entry Starter tier.
Inboxer isn't an email client - it sits on top of your existing Gmail or Outlook and adds a layer across everything that happens around email: AI triage into 8 categories, voice-matched drafts, and a task queue where every extracted commitment links back to the exact email or meeting it came from.
Superhuman supports multiple Gmail and Outlook accounts, although its native Mail experience doesn't provide a traditional unified inbox - you switch between accounts. Inboxer packages source-linked commitments, multi-inbox context, meeting continuity, and approval history into a distinct cross-workflow system that operates alongside Gmail and Outlook: it connects commitments across multiple inboxes and into meetings, keeps one approval history for all of it, and lets a task be shared with a teammate without handing them your whole mailbox or switching them onto a different email client.

Which one is right for you?
Pick Inboxer if…
- You manage more than one inbox and want commitments from all of them in one shared queue.
- You take 5+ meetings a day and pre-meeting prep is eating your morning.
- You want a task you can hand to a teammate without giving them access to your whole mailbox.
- You value action items being extracted automatically, linked back to the exact email or meeting they came from.
- You want one approval history and decision trail spanning both email and meetings.
Pick Superhuman if…
- Your bottleneck is how fast you can read and send - not tracking commitments across mailboxes and meetings - and you want the fastest client UI there is.
- Keyboard shortcuts and a polished native mobile app are non-negotiable.
- Auto-updating thread summaries and an in-inbox AI search assistant (Ask AI) matter more to you than cross-inbox or meeting workflows.
- You want calendar actions inside your mail assistant - Superhuman's MCP searches your calendar and manages events - more than a scheduled brief written before the meeting.
Frequently asked questions
- Is Inboxer cheaper than Superhuman?
- Yes. Inboxer starts at $19/workspace/month (1 user included) with a 7-day free trial; Superhuman Mail starts at $30/month, or $25/month billed annually (Business: $40/month, or $33/month billed annually).
- Does Superhuman have AI triage like Inboxer?
- Yes - Custom Auto Labels (Business tier) gives AI-based categorisation, and Auto Archive (available from the Starter tier) already declutters routine email. Inboxer's triage auto-categorises into 8 buckets and auto-archives most routine noise too; the difference is what the AI produces. Superhuman Mail MCP can search across every connected Gmail and Outlook account - in parallel - from Claude or ChatGPT. What Inboxer adds is a continuously maintained commitment queue: every extracted item stays linked to the email or meeting it came from, and carries one approval history.
- Can I keep my Gmail or Outlook with Inboxer?
- Yes. Inboxer sits on top of your existing mailbox, so you never migrate or change address. Superhuman's standalone client requires switching; its Email Assistant now runs inside Gmail or Outlook without switching. Superhuman handles multiple accounts, and its MCP server searches across all of them; the native Mail experience still works one account at a time rather than as a unified inbox.
- Does Inboxer have a mobile app like Superhuman?
- Not a native app yet; Inboxer is responsive web. Superhuman ships polished native iOS and Android apps, which is a real edge if mobile is your main surface.
- Will either tool send email on its own?
- Neither does. Inboxer never sends an email without your explicit approval of that specific draft. Superhuman keeps you in control too - Auto Draft prepares a reply, you still send it.
