Twistly

Twistly's smart bet is distribution: instead of asking you to learn yet another web app, it lives inside PowerPoint as a ribbon add-in from Microsoft AppSource. That means the decks it generates are native .pptx files you can keep editing with the tools you already know — a real advantage over standalone AI deck makers that lock you into their own editor and export awkwardly. Feeding it a prompt, PDF, Word doc or even a YouTube link to get a first-draft deck with layouts, images and speaker notes genuinely removes the blank-slide stall. It's best treated as a fast first draft rather than a finished product: AI layouts still need a human pass for brand consistency and to fix the occasional generic image or filler bullet. The free core add-in is enough to evaluate it; heavier users will hit the paid generation limits. For anyone who already lives in PowerPoint, it's a sensible, low-friction way to start a deck.
