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.
Mailchimp's recent feed is mostly a 2023–2024 changelog reindex; real shipping is the early-April ecommerce update.
The top of Mailchimp's feed is a reindexing artifact — six historical changelog entries from 2023, 2024, and 2025 (HTTP 404 semantics for invalid template names, expanded webhook retry behavior, DKIM/DMARC sending-domain requirements, attribution-model overwrites of campaign_id, TLS 1.0/1.1 retirement, Audiences BETA endpoints) all tagged with a May 5, 2026 capture timestamp. The actual recent shipping sits below the top window: an early-April 'biggest update ever' aimed at ecommerce — Shopify SMS bidirectional consent sync, Judge.me and Yotpo review integrations, on-brand transactional emails via an in-app editor, a refreshed marketing dashboard, back-in-stock popup forms, and dynamic ecomm data in messaging.

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.

The clear bet is an ecommerce-tilted Mailchimp: review integrations, post-purchase flows, back-in-stock automation, Shopify-side SMS without email. Combined with the older Audiences BETA work that allowed contact creation from a phone number alone, the platform is reshaping around audiences that don't necessarily start with email. Transactional and Marketing surfaces are converging — same in-app editor, same brand controls, same dashboard.
Expect deeper Shopify-side integrations (more bidirectional sync, native checkout-stage triggers), additional review-platform partners beyond Judge.me and Yotpo, and continued blurring of the Marketing/Transactional product line — likely a unified billing or packaging surface eventually. The historical changelog reindex should drop off the front of the feed as new entries push it down.
