Superhuman Platform Help
Helps with everything related to using Superhuman — the fastest AI email client with keyboard-driven workflow, Split Inbox, AI drafting, read receipts, and MCP server for Claude Code integration. Now part of Grammarly (acquired June 2025).
Step 1 — Gather context
If references/learnings.md exists, read it first for accumulated knowledge.
Ask the user:
-
What are you trying to do with Superhuman?
- A) Set up Superhuman for the first time (Gmail or Outlook)
- B) Configure Split Inbox or Auto Labels
- C) Improve AI Write draft quality
- D) Connect MCP server to Claude Code or ChatGPT
- E) Set up CRM integration (Salesforce, HubSpot, Pipedrive)
- F) Compare Superhuman to alternatives
- G) Troubleshoot performance issues
- H) Something else — describe it
-
Which email provider?
- A) Gmail / Google Workspace
- B) Outlook / Microsoft 365
- C) Both
-
Which plan are you on (or considering)?
- A) Starter ($25-30/mo) — basic email, Share Availability, Team Comments
- B) Business ($33-40/mo) — Ask AI, Auto Drafts, Auto Labels, CRM, MCP Server
- C) Enterprise (custom) — SSO, SCIM, audit logs, BYOK
- D) Not sure yet
If the user's request already provides most of this context, skip directly to the relevant step. Lead with your best-effort answer using reasonable assumptions (stated explicitly), then ask only the most critical 1-2 clarifying questions at the end.
Step 2 — Route or answer directly
If the request maps to another skill, route:
- Choosing a meeting note-taker across platforms → "Run:
/sales-note-taker {user's original question}" - AI executive assistant comparison (alfred_ etc.) → "Run:
/sales-alfred {user's original question}" - CRM integration strategy → "Run:
/sales-integration {user's original question}" - Meeting scheduling strategy → "Run:
/sales-meeting-scheduler {user's original question}" - Email tracking strategy → "Run:
/sales-email-tracking {user's original question}"
Otherwise, answer directly from the platform reference below.
Step 3 — Superhuman platform reference
Read references/platform-guide.md for the full platform reference — capabilities, pricing, plan gates, MCP server tools, integrations, keyboard shortcuts, and workarounds.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
You no longer need the platform guide — focus on the user's specific situation.
For improving AI Write drafts:
- Send more emails manually — Superhuman learns from your writing style
- On Business plan, AI Write uses Grammarly's voice model for better results
- Use Cmd+J to trigger AI Write, or let Auto Drafts pre-generate replies
- If tone is wrong, try adjusting the prompt or rewriting manually to train the model
For MCP server setup:
- Requires Business plan or higher
- Enterprise accounts need CSM to enable MCP access
- Configure in your AI client (Claude Code, Claude Desktop, ChatGPT)
- Available tools:
query_email_and_calendar,list_threads,create_or_update_draft,create_or_update_event
For Split Inbox issues:
- Split Inbox auto-sorts into Important, VIP, News, Calendar, Other
- Move mislabeled emails manually — Superhuman learns from corrections
- On Business plan, use Auto Labels for custom AI categorization
- VIP contacts can be pinned to always appear in Important
If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.
Gotchas
Best-effort from research — review these, especially pricing that may change post-acquisition.
- MCP Server requires Business plan ($33+/mo). Starter users cannot connect Superhuman to Claude Code or ChatGPT. This is the #1 developer-relevant feature gate.
- No public REST API. Superhuman has no documented API endpoints, no webhooks, and no Zapier triggers. The MCP server is the only programmatic interface.
- Grammarly acquisition changed pricing. Since June 2025, Superhuman is bundled with Grammarly, Coda, and Go. Standalone Superhuman Mail requires at least Starter ($25-30/mo). Some users report AI features slowed post-acquisition.
- CRM integrations are Business-only. Salesforce, HubSpot, and Pipedrive connectors require the Business plan. No other CRMs supported.
- No meeting notes. Unlike Fyxer or dedicated note-takers, Superhuman is email+calendar only. Route to
/sales-note-takerfor meeting intelligence. - Read receipts have privacy limits. Apple Mail Privacy Protection blocks pixel tracking. Business plan's Recent Opens Feed is best-effort, not reliable for all recipients.
- Mobile app is limited. Desktop keyboard-driven workflow is the core experience. Mobile lacks many power features.
- Self-improving: If you discover something not covered here, append it to
references/learnings.mdwith today's date.

Examples
Example 1: Connect Superhuman MCP server to Claude Code
User says: "How do I connect Superhuman to Claude Code so I can manage email from the terminal?" Skill does:
- Confirms user needs Business plan ($33+/mo) for MCP server access
- Explains the 4 available MCP tools (query, list threads, draft, events)
- Walks through MCP configuration in Claude Code settings
- Notes that Enterprise accounts need CSM to enable access first
- Warns: MCP can draft and send emails — review carefully before authorizing send actions Result: User has Superhuman MCP connected to Claude Code with clear understanding of capabilities and risks
Example 2: Compare Superhuman to Fyxer for inbox productivity
User says: "Should I use Superhuman or Fyxer AI for managing my sales inbox?" Skill does:
- Compares: Superhuman focuses on speed + keyboard workflow + Split Inbox; Fyxer focuses on AI organization + voice-trained drafts + meeting notes
- Notes Superhuman has MCP server for Claude Code; Fyxer has no automation surface
- Compares pricing: Superhuman $25-40/mo vs Fyxer $22.50-50/mo
- Notes Fyxer includes meeting notes; Superhuman is email+calendar only
- Recommends Superhuman if speed and keyboard workflow matter most; Fyxer if you want meeting notes and hands-off inbox sorting Result: Clear comparison based on workflow preference
Example 3: Troubleshoot slow AI features
User says: "Superhuman AI is really slow since the Grammarly acquisition — emails take minutes to open" Skill does:
- Acknowledges this is a widely reported issue post-July 2025 acquisition
- Suggests: check internet speed, try disabling Ask AI/Auto Drafts temporarily to isolate
- Notes that clearing the Superhuman cache (Cmd+K → "Clear cache") sometimes helps
- If persistent, recommends contacting support with browser/OS details
- If AI features are the main value, suggests evaluating alternatives like Shortwave ($7/mo) or Fyxer ($22.50/mo) Result: Troubleshooting steps with honest assessment of post-acquisition issues
Troubleshooting
AI Write drafts sound generic or wrong
Symptom: AI-generated replies don't match your tone or get details wrong Cause: AI Write learns from your sent email history. Short history or inconsistent style produces poor drafts. Post-acquisition, the model uses Grammarly's engine which may behave differently than the original. Solution: Send more emails manually to build training data. Use Cmd+J and provide specific instructions. Always review drafts before sending. If quality doesn't improve after 2+ weeks, the tool may not fit your communication style.
Split Inbox miscategorizing emails
Symptom: Important client emails ending up in News or Other instead of Important Cause: Split Inbox is AI-driven and takes time to learn your patterns Solution: Manually move mislabeled emails to the correct split — Superhuman learns from corrections. Pin VIP contacts. On Business plan, use Auto Labels for custom categorization rules. Give it 1-2 weeks of consistent corrections.
CRM integration not syncing
Symptom: Emails and activity not appearing in Salesforce/HubSpot/Pipedrive Cause: CRM integrations are Business plan only and require explicit setup Solution: Verify you're on Business plan. Check Superhuman Settings → Integrations → reconnect the CRM. Ensure the contact exists in both systems. If sync is delayed, allow up to 15 minutes for propagation.
