What is SlickText?
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.
What is Superhuman?
Superhuman goes all-in on AI connectivity and mobile parity in one sprint.
Superhuman has moved well past its speed-focused roots. The complete iOS/Android redesign delivers a mobile experience on par with the desktop app, while the multi-account MCP connector makes Superhuman the only email client that exposes multiple inboxes simultaneously to Claude and ChatGPT. The themes refresh is cosmetic, but the AI integrations are structural. Auto Drafts 2.0 eliminates the blank-page problem on every reply.
SlickText vs Superhuman: editorial side-by-side
SlickText
3.8COMMS
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
◆ Current state
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.
◆ Where it's heading
The product is broadening from SMS-only toward a multi-format messaging stack where channel trust and branding matter. RCS gives SlickText a credible answer to the deliverability and impersonation problems that plain text marketing can't solve on its own, and slots it against enterprise rivals it keeps writing comparison content about.
◆ Prediction
Expect RCS to move from 'basic' to feature-complete — branded sender profiles, rich cards, and read receipts — and to become a headline differentiator in the comparison content SlickText already publishes against Attentive and EZ Texting.
Superhuman
6.3COMMS
Superhuman goes all-in on AI connectivity and mobile parity in one sprint.
◆ Current state
Superhuman has moved well past its speed-focused roots. The complete iOS/Android redesign delivers a mobile experience on par with the desktop app, while the multi-account MCP connector makes Superhuman the only email client that exposes multiple inboxes simultaneously to Claude and ChatGPT. The themes refresh is cosmetic, but the AI integrations are structural. Auto Drafts 2.0 eliminates the blank-page problem on every reply.
◆ Where it's heading
Superhuman is positioning itself as the authoritative communications layer for AI agents — not just a fast email client. The MCP plugin and multi-account connectors are the rails; everything else (calendar on Android, mobile redesign, label sync) fills in the gaps needed to make that hub position credible. Expect each subsequent release to deepen AI orchestration over the inbox rather than adding standalone features.
◆ Prediction
AI-driven scheduling that bypasses manual share-availability flows is the next likely move — the calendar-on-Android feature and AI connectors are converging on a native booking experience that would let an AI agent schedule on a user's behalf without leaving Superhuman.
