The Infectious Generosity Guru (TIGG) is a free, AI-powered chat assistant from Infectious Generosity that guides users through a Generosity Profile, brainstorming, planning and content creation to turn philanthropic intentions into action; because TIGG was explicitly trained on the book’s ideas, it operationalizes themes from Chapter “Your Capital And the Power of Generosity” (Part 1: The Purposeful Investor) and is included—Stuart’s pick—to illustrate how AI can help purposeful investors and individuals design, execute and scale technology-driven giving strategies and social-impact initiatives.
