Chris demonstrates Anthropic’s Fable 5 (Mythos) by prompting it to recreate Notion. In two prompts and ~45 minutes the model produced a working Electron desktop app with Convex backend, editor blocks, themes, emoji picker and databases. The video shows the demo, practical setup, costs, and the implications for product development, validation and distribution.
– Technical process: Uses the Claude desktop (co-work & code) set to Fable 5 Max; the model spent ~10 minutes planning, researched Notion, then scaffolded an Electron app with a Convex database and server wiring.
– Demo output: Delivered a near-identical Notion-like UI and features — blocks (tables, text, images), multiple database views, emoji picker, light/dark themes, animations and working CRUD behavior.
– Implications: Building complex apps is now fast but expensive; the real bottlenecks shift to idea selection, validation, design quality and distribution rather than implementation.
– Practical advice: Validate specs with cheaper models (e.g., Opus) before using Fable 5; use subscription access while available and treat Fable 5 as a high-cost accelerator for proven concepts.
Quotes:
Two prompts, 45 minutes — we cloned a $10 billion app.
It spent about 10 minutes just thinking before it even did anything.
I don’t think I could tell the difference — this is basically Notion.
