Arcade's AI video tool now works inside Claude, ChatGPT and Gemini via MCP.
Arcade's releases are almost all about AI video. The November release adds an Arcade MCP so users can create and edit videos from Claude, ChatGPT, Gemini and other assistants, with credit costs shown in the chat. It also adds 60 native voices in 15 more languages and one-click variations of a single video. In October, AI video got its own home and users could pick the model behind each video.
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).

Arcade spent the autumn turning its editor into an AI video studio, with style references, curated scenes and model choice. It is now taking that studio into the assistants people already use, and charging per edit in credits. Localisation and variations push it toward producing many versions of one video for different audiences.
Expect more agent-facing work, such as deeper MCP actions or usage-based pricing detail, since the MCP launch already exposes credit costs per edit.

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.
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.
