Todd Saunders reports that on June 10, 2026 he used Claude to transcribe a customer call while Mythos / Fable autonomously generated requested features in real time. During the ~15-minute conversation the system captured desired workflows and produced a fully working product by the call's end, demonstrating an autonomous looped build triggered directly from the customer discussion (video included).
On 2026-06-10 @toddsaunders ran a customer call while Claude (Anthropic) transcribed in the background and used Mythos / Fable to build features in real time.
Mythos / Fable is unbelievable.
Was on a customer call today and had Claude transcribing in the background.
As they were telling me about the features they wish their current software had, Claude was building the features in real time.
By the end of the call I was able to show a fully working product, with the exact workflow they mentioned 15 minutes earlier.
Autonomous looped building triggered from a customer call. 🤯
