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.
MySignature turned its digital business card into a lead-capture surface, then instrumented it.
MySignature started as an email signature designer and has spent the last year building out a second product around digital business cards. August was the month that surface stopped being a way to hand over contact details and became a way to collect them: a Collect Contacts form block, a Contacts list behind it, and analytics on views, clicks, QR scans and traffic sources. The signature editor keeps advancing separately, with reply and forward variants the newest addition.

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 direction is from presentation to acquisition. Design tooling — drag mode, AI layout suggestions, banner campaigns — made signatures look better; the card work makes them measurable and makes them capture. That is a different business: a signature is a design asset, a card that collects and reports on leads is a small marketing channel, and the Contacts list is the first place MySignature holds customer data of its own.
Expect the Contacts list to grow the obvious next pieces — export, tagging, and a route into the CRMs and marketing tools its Teams customers already run.
