Who each one suits

Shortwave

  • Gmail and Google Workspace users who want AI to triage and draft email
  • Teams that want to comment on and assign email threads internally
  • People who want Google Inbox-style bundles on top of Gmail

Superhuman Mail

  • People on Gmail or Outlook who work through a high volume of email
  • Teams that want to share and comment on threads instead of forwarding them
  • Sales teams on HubSpot, Salesforce or Pipedrive (Business plan and up)

Worth knowing

Shortwave

  • Sign-in requires Gmail or Google Workspace. Microsoft 365 and Exchange are not supported, and other providers only work by forwarding mail to Gmail.
  • Paid plans start at $18 per seat a month for individuals and $30 on the business plans, and AI usage on every plan is capped by a daily quota.
  • The Business plan limits AI search to 5 years of history and allows 3 AI filters.
  • Native apps cover Mac, Windows, iOS and Android; other platforms rely on the web app.

Superhuman Mail

  • There is no free plan, and the pricing page does not mention a free trial.
  • Built for Gmail and Outlook accounts; the vendor lists no other email providers.
  • Auto Drafts, Ask AI and the HubSpot, Salesforce and Pipedrive integrations are not included in Starter.
  • Starter and Business stop at 25 seats; single sign-on and SCIM are Enterprise only.

Key features

Shortwave

AI assistant
Prompt the assistant to organize the inbox, write in your own voice, search mail or schedule a meeting. It can also browse the web and analyze attachments.
AI filters
Describe a rule in plain English and it labels, stars or archives incoming mail. Business includes 3 AI filters, Premier 10 and Max 50.
Split inbox and bundles
Divide the inbox into tabs by sender, label or custom query, and triage promotions, newsletters and updates in bulk as bundles.
AI search
Ask questions across your mail instead of keyword searching. Business reaches back 5 years and reads up to 50 threads per search; Premier removes the history limit.
Team collaboration
Share a live thread with teammates, discuss it in private comments, assign emails with a done status, and keep shared labels, snippets and saved prompts.
Scheduling and follow-ups
The assistant checks availability, creates calendar events and writes scheduling emails. Snooze, delivery schedules and no-reply reminders are also included.

Superhuman Mail

Split Inbox
Divides the inbox into separate tabs, for example mail from teammates, VIPs or specific tools, so each stream can be worked through on its own.
Keyboard shortcuts and Snippets
Most actions have a keyboard shortcut, and Snippets insert saved phrases, paragraphs or whole emails as you type.
Superhuman AI
Write with AI, Instant Reply, Auto Summarize and Auto Labels are on every plan. Auto Drafts, Ask AI and the Mail MCP server need Business or Enterprise.
Reminders, snooze and send later
Set a follow-up reminder that fires if nobody replies by a chosen time, snooze threads until they are needed and schedule when a message is sent.
Shared conversations and comments
Share a live view of a thread with teammates, comment on it, work on shared drafts and see when a colleague is already replying.
Calendar and scheduling
See the day's or week's calendar next to an email, create events, share availability and send booking links, with Zoom, Google Meet and Microsoft Teams links.
