Cantata
Claude Build DayCantata lets one person run an engineering org by voice. Shout an idea and watch it become a running app on screen built by a fleet of Claude agents you command by talking, never touching the keyboard. Interrupt it mid-sentence and it stops and redirects like an employee; say "undo that" and it git-reverts; say "open what you built me this morning" and it remembers. A Sonnet concierge talks, an Opus 4.8 Director routes, and sandboxed, cost-capped workers build in parallel. Best of all, saying "stop" goes straight to the machines with no model in the loop. It was built and bug-checked by Opus 4.8 orchestrating itself. JUDGE NOTE: The railway deployment is real but ephemeral, if you reload you lose it. It would normally be a local electron app that modifies files on your system.
