INSIGHT - CREATE THE MIND READER Created by professional mentalist Paul Brook, InSight makes your participant the mind reader. One participant thinks of anything, the other participant reveals it. Use your existing method to capture a word, but instead of revealing it yourself, give that power to someone else. Itβs far more engaging and feels significantly more impossible. And because it happens in their hands, with you as the observer, it feels completely real. FLEXIBLE INPUT, TOTAL CONTROL Capture via typed input, Inject, clipboard, API, or URL Scheme. Expand further with camera input and additional APIs (In-App Purchases), and control exactly how the process unfolds. UNLOCK MORE WITH PRO FEATURES Enhance your performances with optional Pro features (In-App Purchases): β’ Camera Input: capture written words using your iPhone camera β’ Additional API Inputs: expand your input options with two extra APIs β’ Output to Image: transform your reveal into a fully custom visual β’ FontFactory: add natural variation for authentic handwritten text β’ Apple Watch Peek: access information discreetly on your wrist β’ Output to Clipboard: pass your reveal seamlessly between apps ALWAYS EVOLVING InSight is designed as a living toolset for modern mentalism - continuously refined to give you more control, more flexibility, and more impact.
