What is Crisp?

Crisp ships RTM API events for verification and unread acknowledgement; the visible feed is docs-only and sparse.

Three new RTM API events shipped in a single batch on February 11: identity:verify:request, session:updated (with the verification list), and message:acknowledge:unread:send. Each lets integrators react in real time to verification or unread state without polling. The fourth entry is a truncated August 2025 version of the identity-verification event.

What is Superhuman?

Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.

Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

Crisp vs Superhuman: editorial side-by-side

0.0

Crisp ships RTM API events for verification and unread acknowledgement; the visible feed is docs-only and sparse.

◆ Current state

Three new RTM API events shipped in a single batch on February 11: identity:verify:request, session:updated (with the verification list), and message:acknowledge:unread:send. Each lets integrators react in real time to verification or unread state without polling. The fourth entry is a truncated August 2025 version of the identity-verification event.

◆ Where it's heading

What's visible is Crisp quietly extending its real-time API surface for integrators rather than shipping user-facing features. Whether the customer-messaging product itself is moving — AI assistance, channel additions, automations — isn't visible from this docs feed.

◆ Prediction

Expect more incremental RTM events as integrators request hooks. To read product direction we'd need to re-point the source to the release blog or product-news feed; this docs surface won't show user-visible changes.

S6.3

Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.

◆ Current state

Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

◆ Where it's heading

Superhuman is positioning itself as the email client AI agents operate, not just one humans use — its MCP, Draft Sync with Gmail and Outlook, and now a Codex plugin all point the same way. In parallel it keeps sharpening Split Inbox (reorder, hide-empty, a Reminders split) and mobile flow. The bet is agent-operability plus opinionated triage as the wedge against Gmail and Outlook.

◆ Prediction

Expect more agent surface — additional MCP hosts and agent-drivable actions — alongside continued Split Inbox personalization. The entries point to agentic email as the primary investment line.
