One term a day. The language of modern work. The people shipping real things share a vocabulary: prompts, models, design systems, launches. PromptHaus teaches you one of those words every day. Definition on the front. A real example from work on the back. Thirty seconds, then on with your day. Workers with AI skills can earn a wage premium of around 62% (PwC 2026 Global AI Jobs Barometer). Vocabulary is where that starts, and it tends to compound. SEEK. SENSE. SHARE. PromptHaus runs on Personal Knowledge Mastery, the Seek · Sense · Share framework (Jarche, 2014). Seek: one hand-written term matched to where you're headed. Sense: quick checks, spoken practice and feedback designed to make it stick. Share: a Skills Wallet with credentials other people can verify. Measurable. Verifiable. Yours for life. SEE IT IN MOTION Every term now includes an animated isometric illustration. Whether you're a visual learner or you like studying technical drawings while you build your literacy, you'll love this one. Illustrations also appear in micro-lesson Broadcasts, on extra large iOS widgets and across the web experience. BUILT FOR iOS 27 • Apple Intelligence. Foundation Models read your own PDFs, notes and code on device and turn them into a private deck. Your files stay on your iPhone unless you say otherwise. • Private Cloud Compute. When a file is too big for on-device, you can send it to Apple's Private Cloud Compute instead, with the same privacy protections and a limit you can see. • Visual Intelligence. Point your camera at a screen, a whiteboard or a doc, or take a screenshot, and ask "Explain this in PromptHaus." • Siri and App Intents. "What does latency mean in PromptHaus?" "Save this term." Your terms show up in Spotlight too. • iPhone Duo. Open it and the term sits on one page while you practice on the other. Close it and today's term lives on the outer display. • Widgets and Live Activities. Today's term on your Home Screen.
