What is Superhuman?
Superhuman is becoming an email agent, not an email client
Superhuman has spent the last two months turning the inbox into an agent surface: an MCP server, a Codex plugin with prebuilt skills, Draft Sync so external assistants can write into Gmail and Outlook, and now Auto Drafts that pre-write a reply to every message that needs one. The rest of the roadmap — Android calendar, multi-day iOS views, notification quick-reply — is parity work running underneath the AI push.
What is Grain?
Grain reframes itself as the meeting layer for your AI, shipping a ChatGPT plugin and MCP tools.
Grain is a meeting-recording and notes product that has spent recent releases wiring itself into AI assistants. After adding one-click send-to-Claude/ChatGPT and an MCP server in the spring, it now ships as a full ChatGPT plugin with a broader MCP tool set and sharper auto-notes. The underlying capture stack (live notepad, meeting detection, clipping, uploads API) is mature.

Superhuman is becoming an email agent, not an email client
◆ Current state
Superhuman has spent the last two months turning the inbox into an agent surface: an MCP server, a Codex plugin with prebuilt skills, Draft Sync so external assistants can write into Gmail and Outlook, and now Auto Drafts that pre-write a reply to every message that needs one. The rest of the roadmap — Android calendar, multi-day iOS views, notification quick-reply — is parity work running underneath the AI push.
◆ Where it's heading
The direction is to reduce the human to an editor. Auto Drafts already claims 60% of replies sent unedited and pulls context from calendar and the web, while the MCP surface lets any agent triage, draft, and schedule. Expect the mobile and calendar catch-up to continue while the AI layer absorbs more of the reply workflow.
◆ Prediction
Next likely move is wiring Auto Drafts into more tools — the changelog already promises Slack, CRM, and meeting-notes context — pushing toward send-ready replies drawn from a user's whole stack.

Grain reframes itself as the meeting layer for your AI, shipping a ChatGPT plugin and MCP tools.
◆ Current state
Grain is a meeting-recording and notes product that has spent recent releases wiring itself into AI assistants. After adding one-click send-to-Claude/ChatGPT and an MCP server in the spring, it now ships as a full ChatGPT plugin with a broader MCP tool set and sharper auto-notes. The underlying capture stack (live notepad, meeting detection, clipping, uploads API) is mature.
◆ Where it's heading
Grain is repositioning from a standalone recorder toward an interoperable context source that feeds meeting decisions and rationale into whatever AI tool a team already uses. Each release lowers the friction of getting meeting data out of Grain and into an assistant, betting that distribution inside ChatGPT and MCP clients matters more than owning the end-user surface.
◆ Prediction
Expect Grain to extend its plugin and MCP coverage to more assistants and deepen project-level context sharing, competing on how cleanly meeting data lands in AI tools rather than on the recorder UI itself.
