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's comment and DM inbox is in beta as content marketing fills the feed.
Swello is a French social media scheduling tool whose changelog mixes product releases with marketing. The newest entry announces its 2027 Social Media Calendar of more than 450 dates in PDF, .ics and print, after a podcast episode and a webinar replay earlier in October. The last product release added 3:4 Instagram posts and CSV export of posts, and confirmed the comment and DM inbox is in beta.

◆ 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's comment and DM inbox is in beta as content marketing fills the feed.
◆ Current state
Swello is a French social media scheduling tool whose changelog mixes product releases with marketing. The newest entry announces its 2027 Social Media Calendar of more than 450 dates in PDF, .ics and print, after a podcast episode and a webinar replay earlier in October. The last product release added 3:4 Instagram posts and CSV export of posts, and confirmed the comment and DM inbox is in beta.
◆ Where it's heading
Swello is building toward team and agency workflows: post approval, then comments on drafts, then CSV export for reporting, with some features reserved for the Large plan. The unified inbox in beta moves it from publishing into engagement management, while the changelog doubles as a channel for its podcast, webinars and guides.
◆ Prediction
The likeliest next release is the inbox leaving beta. The AI features mentioned in September have not shipped, and the entries give no timing for them.
