We have presentations we create repeatedly with slight variations. Customer reports, monthly updates, proposal templates. Creating each one manually was tedious. Same structure, different details, every single time. Now: base content in a doc, AI PowerPoint generator (Gamma) creates the variant, quick edit, done. Monthly customer reports that took 3 hours each take 30 minutes. The AI doesn't help with creative presentations. It helps with repetitive ones. That's where the time savings are most real.
