Deck homepage screenshot, productivity & writing AI tool

Our take: Deck suits busy founders, sales and finance people who prefer to delegate research, follow-ups and daily briefs to an assistant they reach by plain email instead of a new app.

Main limitation: Pricing, free access and the privacy and docs pages were not available on official pages, and connection is limited to CC or forwarding for now.
