Your Gmail support threads, reviewed.
If customers email you in Gmail, there is no QA tool watching those replies. Supportman for Gemini reviews a thread on request: a score, comments on the exact lines that hurt, and a better reply.
Founders and small teams answering support from a shared inbox get the same feedback a dedicated QA program gives larger teams.
Supportman for Gemini is in early preview. The demo is open now, no account needed.
Connect the demo in under a minute.
The demo server is open to anyone. Its reviews are rule-based: instant, free, nothing stored, and no AI on our side. It works in any assistant or agent that lets you add a custom MCP server.
https://supportman.io/mcp
- Step 1
Add https://supportman.io/mcp as a custom connector (MCP server) in Gemini. If it asks about sign-in, choose no authentication.
- Step 2
Ask: “Show me a sample Supportman review.”
- Step 3
Paste a real thread, an email chain or a reply you are about to send, and ask Supportman to review it.
A code review, for support replies.
Paste or point at any conversation: a Gmail thread, a Slack thread, a helpdesk transcript. Supportman scores it on the same four categories it already uses for AI conversation scoring in Intercom, then tells you exactly what to change. Example below.
The thread you paste

- No acknowledgement that this is the second broken order. Lead with that.
- Asks for the order number, which is already on the conversation.
- No outcome offered. Say what happens once the photo arrives.
Suggested reply · I'm sorry, a second broken order is not okay. Send a photo when you can and I'll refund you the same day, no need to return it.
- “Review my last reply in this Gmail thread.”
- “Was this customer happy by the end? Score it.”
- “Rewrite this reply to be shorter and warmer.”

Supportman for Gemini, answered.
Does Supportman read my whole inbox?
No. Supportman only sees the thread you ask it to review.
Is this a Google product?
No. Supportman is independent and connects through the open Model Context Protocol (MCP).
Is this available today?
A free demo is: add https://supportman.io/mcp to your assistant as a custom MCP server, no account needed. Its reviews are rule-based. The full product, with AI scoring and your Intercom data, is in early preview: request access and we will add you as we open it up, platform by platform.
What does a review score?
The same four categories Supportman already uses for AI conversation scoring in Intercom: brand voice and tone (20), knowledge and accuracy (30), resolution and helpfulness (30), and communication efficiency (20). You get a 0–100 quality score, a predicted CSAT from 1 to 5, line-level comments, and a suggested better reply.
Do I need Intercom to use it?
Not for reviewing a pasted conversation. Connecting an Intercom workspace adds the second half: asking about your real CSAT, DSAT conversations, Fin, and agent performance.
