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 keeps layering AI and Split Inbox refinements onto its speed-first email client.
Superhuman is pushing on two fronts: AI-assisted workflows (personalized availability sharing, voice-to-draft, an email MCP for Claude and ChatGPT, and cross-client draft sync) and Split Inbox ergonomics (reorder, hide-empty, a Reminders split). Mobile is gaining quick-reply from notifications.
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
5.0COMMS
Superhuman keeps layering AI and Split Inbox refinements onto its speed-first email client.
◆ Current state
Superhuman is pushing on two fronts: AI-assisted workflows (personalized availability sharing, voice-to-draft, an email MCP for Claude and ChatGPT, and cross-client draft sync) and Split Inbox ergonomics (reorder, hide-empty, a Reminders split). Mobile is gaining quick-reply from notifications.
◆ Where it's heading
The product is positioning itself as an AI-driven inbox you can also drive from external agents; the MCP and draft sync let AI tools operate on Superhuman Mail while the user reviews and sends. Alongside that, steady UX polish keeps the Split Inbox model flexible.
◆ Prediction
Expect deeper agent integration, with more of the inbox controllable via MCP, and continued personalization so AI output matches each user's tone and rules.
