With PK-Ink App, you can magically move permanent ink drawn on your mobile screen! Key Features • The spectator chooses the exact spot where the ink will appear. • The spectator can select from a variety of marker colors or designs — or you can upload your own drawings. • Move the drawing without touching the phone, using remote control or advanced hand-gesture recognition. Multiple gesture options included: pinch, index finger pointing, open-hand (5 fingers), and more — all highly reliable. • Multiple powerful finales: the spectator will be unable to erase the ink they just saw move. You start clean and end clean. • No internet connection required (unless you use integrations). • Integrate your favorite magic apps with an Ouija-style effect: Imagine the spectator searching for a word in apps like Inject or Elips, and the ink begins to move toward each letter or number — triggered by hand gestures, volume buttons, or fully automatic mode, gliding smoothly across the entire alphabet. Use this as a paranormal illusion with the built-in video animation feature, or as a psychic/magical effect by moving the ink across any Ouija board image you’ve downloaded. • Video instructions available in English and Spanish. • Extremely easy to use — no complex setup or configuration required.

Onyx is a revolutionary utility that allows you to modify a captured image in real-time using variable input data. Using cutting edge AI, Onyx lets you remotely create seamless alterations to photos moments after they've been taken - all with your spectator's camera. For example: — Make a playing card appear in your spectator's wallet. — Morph your spectator's shadow to look like their thought of animal. — Take a photo of your spectator holding a signed card. They name *any* other card. The signed card in the photo transforms to match their thought. — Supplement your Gypsy Queen routine with Onyx: zoom in on a photo of your spectator holding the Queen of Hearts for the reveal. — Reveal a thought-of word, name, or initials hidden naturally in the light reflections of a spectator's eye. — Change the time on a photo of a clock. — Remove your spectator's wristwatch in a photo, making it sbeem that it was removed earlier. ...and more! If you can describe it, Onyx can likely create it. Onyx is particularly great for revealing something ephemeral. Photograph a shadow, clouds, a TV screen or more, and Onyx will realistically insert their free choice. * Variable Delayed Input Inspired by the popular variable trigger system featured in DFB X, Onyx pauses and automatically waits for input, letting you remotely modify a photo *after* it's been taken. * Cutting Edge Technology Take a photo, then have your spectator make a free choice. Onyx's advanced technology seamlessly transforms the photo remotely. * Create Unlimited Effects Change signed playing cards, reveal initials and names, or modify writing. Reveal *anything you can imagine* within a genuine photo you just took. * Your Integrations. Their Camera The effect happens entirely with the spectator's camera. With Onyx's powerful integrations, your phone never needs to leave your pocket. * Invisible, Advanced Technology As only the spectator's device is in play, Onyx remains hidden and inconspicuous. * Third Party Integrations Use your favourite magic apps' input methods, including: — Earworm's covert typing Web Search & Notes input — Native voice input — Native clock swipe input — WebFX's Wrist Gestures — WikiTest — PeekSmith — Bridge ...and any compatible third-party app. # Introducing: Onyx Print Onyx Print brings Onyx’s digital effect into the real world. # Produce Physical Photographs Instead of revealing information only on a screen, Onyx Print can generate and automatically print images on a pocket printer, allowing you to produce a real photograph from your wallet, pocket, or envelope for a powerful ending. # Dynamic Prompting Onyx Print uses the same dynamic prompting and covert input system that powers Onyx. Use any of Onyx’s input methods, and Onyx Print will automatically generate and print an image to match. # Use Your Own Photos You can even modify existing photos. For example: have Onyx Print set up with a photo of yourself and have a spectator name any place in the world. Onyx Print will then create and automatically print a realistic photo of you in that exact location, ready to reveal. # Works With Other Apps Onyx Print can even monitor your photo library and automatically print images saved by other apps. When an app saves a photo, Onyx Print can print it. Onyx Print is an in-app purchase within Onyx, and currently supports the Instax mini Link+, with plans for additional printers in the future. Onyx is a tool specifically designed for entertainment purposes. It uses purchaseable in-app credits or a funded OpenRouter account for best-in-class automatic edits. Onyx supports: Arabic, Bengali, Bulgarian, Chinese simplified and traditional, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Thai, Turkish, Ukrainian, Vietnamese
