What is Cello?
Cello is wrapping its referral platform in AI assistants — for growth managers, referrers, and now AI coding tools via MCP.
Cello has been shipping every week, layering in three parallel AI surfaces: an in-portal Assistant for growth managers, AI-powered sharing-message suggestions for referrers, and a brand-new MCP Server that lets developers' AI tools introspect, validate, and recommend changes to a Cello account. Around those, the team is hardening the developer experience (Event Feed for integration debugging, Flutter SDK in beta) and polishing the referrer widget (dark mode, dual-offer layouts, micro-loop reminders).
What is Swello?
Swello adds a notification center for approvals, mentions and expired logins.
Swello is a French social media scheduling tool whose changelog mixes product releases with marketing. October added TikTok analytics from the Large plan, November 5 redesigned the sidebar, and November 12 added a notification center on every plan that collects approval requests, mentions and expired social profile tokens in one place.

Cello is wrapping its referral platform in AI assistants — for growth managers, referrers, and now AI coding tools via MCP.
◆ Current state
Cello has been shipping every week, layering in three parallel AI surfaces: an in-portal Assistant for growth managers, AI-powered sharing-message suggestions for referrers, and a brand-new MCP Server that lets developers' AI tools introspect, validate, and recommend changes to a Cello account. Around those, the team is hardening the developer experience (Event Feed for integration debugging, Flutter SDK in beta) and polishing the referrer widget (dark mode, dual-offer layouts, micro-loop reminders).
◆ Where it's heading
Cello is positioning itself as the AI-augmented referral platform across three personas: program operators get AI recommendations and benchmarks, end-users get AI-assisted personalization, and developers get an MCP Server they can wire into their own coding agent. Performance Benchmarks and Recommendations indicate Cello also wants to own the optimization layer, not just the rails — telling customers what to do next, not only what's happening.
◆ Prediction
Expect the MCP Server and AI Assistant to converge — likely an agentic workflow where the AI Assistant proposes a change and an MCP-connected coding agent applies it. Mobile (Flutter, the existing React Native and iOS/Android components) will probably keep gaining feature parity since referral flows are still desktop-biased today.
Swello
5.0MARKETING
Swello adds a notification center for approvals, mentions and expired logins.
◆ Current state
Swello is a French social media scheduling tool whose changelog mixes product releases with marketing. October added TikTok analytics from the Large plan, November 5 redesigned the sidebar, and November 12 added a notification center on every plan that collects approval requests, mentions and expired social profile tokens in one place.
◆ Where it's heading
The recent releases point at teams rather than solo community managers: a reorganized interface, then a way to follow who needs to approve or fix what. Collaboration features are becoming the main product thread between marketing posts.
◆ Prediction
Expect more team workflow features around approvals, such as assignment or status views, building on the new notification center.
