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:

1. 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

2. Which email provider?

   • A) Gmail / Google Workspace
   • B) Outlook / Microsoft 365
   • C) Both

3. 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:

1. Send more emails manually — Superhuman learns from your writing style
2. On Business plan, AI Write uses Grammarly's voice model for better results
3. Use Cmd+J to trigger AI Write, or let Auto Drafts pre-generate replies
4. If tone is wrong, try adjusting the prompt or rewriting manually to train the model

For MCP server setup:

1. Requires Business plan or higher
2. Enterprise accounts need CSM to enable MCP access
3. Configure in your AI client (Claude Code, Claude Desktop, ChatGPT)
4. Available tools: query_email_and_calendar, list_threads, create_or_update_draft, create_or_update_event

For Split Inbox issues:

1. Split Inbox auto-sorts into Important, VIP, News, Calendar, Other
2. Move mislabeled emails manually — Superhuman learns from corrections
3. On Business plan, use Auto Labels for custom AI categorization
4. 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-taker for 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.md with 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:

1. Confirms user needs Business plan ($33+/mo) for MCP server access
2. Explains the 4 available MCP tools (query, list threads, draft, events)
3. Walks through MCP configuration in Claude Code settings
4. Notes that Enterprise accounts need CSM to enable access first
5. 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:

1. Compares: Superhuman focuses on speed + keyboard workflow + Split Inbox; Fyxer focuses on AI organization + voice-trained drafts + meeting notes
2. Notes Superhuman has MCP server for Claude Code; Fyxer has no automation surface
3. Compares pricing: Superhuman $25-40/mo vs Fyxer $22.50-50/mo
4. Notes Fyxer includes meeting notes; Superhuman is email+calendar only
5. 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:

1. Acknowledges this is a widely reported issue post-July 2025 acquisition
2. Suggests: check internet speed, try disabling Ask AI/Auto Drafts temporarily to isolate
3. Notes that clearing the Superhuman cache (Cmd+K → "Clear cache") sometimes helps
4. If persistent, recommends contacting support with browser/OS details
5. 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.
