Summary
Greg Isenberg walks through a set of practical prompts for Claude Fable 5.2, Anthropic’s newest top-tier model, focused on turning its capabilities into income and productivity gains. The video demonstrates the prompts live rather than just listing them.
The money-making examples include asking Fable 5.2 to audit an entire business (website, pricing, onboarding, emails and top competitors) over a long autonomous run, completing a freelance job end to end and selling it as a fixed-price productized service, and spinning up sub-agents to research 100 niches at once. Isenberg also tests it on a real Upwork equity-research listing priced at $450, and suggests rebuilding decade-old spreadsheet-based systems as simple web apps for clients. He cites Anthropic’s reported jump in freelance task scores from 21% to 41%.
On the productivity side, he covers a “grill me” interview prompt that turns your answers into a reusable skill file, using the model’s stronger computer-use abilities to operate apps that never had an API, and a “red team my plan” prompt that argues against a business plan like a skeptical investor. The video also touches on marketing and content workflows and on using the model for hardware design ideas. It is aimed at founders, freelancers and agency owners looking for concrete ways to apply the new model.
