Simulon. The camera for your imagination. Bring imagined characters, real objects and your own designs into the world around you. Compose with your camera, capture a lifelike image and turn it into a video by describing what happens next. No 3D or animation experience needed. CREATE FROM AN IDEA Start with words, a photo or your own design. Turn a sketch into a character or take a concept off the page and into a real setting. CLONE REALITY Create from photos of something real, whether it's your pet, a favourite car or a sculpture. Keep its familiar look or imagine something different. Give your pet a new outfit, shrink a car onto your desk or bring a statue to life. MAKE THE WORLD YOUR SET Place your subject in augmented reality. Adjust its size and position, then move around to find your angle. AI rendering brings it into the scene with lifelike lighting, shadows and reflections. DIRECT WHAT HAPPENS NEXT Describe how your subject moves and what happens in the scene to create a video. From a small gesture to an unexpected adventure, you direct the action without animating by hand. Keep your subjects in a personal library and return to them in new locations and new stories. Make something just for fun, develop an idea or create something to share with the world. GET STARTED Try Simulon with starter assets and included free usage. Creating custom assets requires a paid plan. Simulon Plus and Pro offer additional features and monthly usage. Usage limits apply. Shape reality.

GREYSET turns your iPhone into a real film camera for AI filmmaking. Point your phone, walk around, and operate a virtual camera inside your 3D previz scene — then export the camera move as a reference for AI video tools like Seedance, Kling or Veo. HOW IT WORKS • Open the GREYSET web app on your computer (greyset.app) and build a quick greybox scene — characters, props, action. • Scan the QR code with this app. Your phone becomes the camera. • See the live render from your computer right on the phone, framed exactly like the final shot. • Walk, pan, tilt — real handheld motion, captured in 3D. • Tap REC to record a take. The camera move lands in your scene, ready to export. FEATURES • Real AR camera tracking — your steps become dolly moves • Live viewfinder streamed from your desktop scene (or low-lag on-device AR preview) • Lens picker (16–135 mm), Handheld / Steadicam / Dolly movement styles • Joysticks for fine moves: truck, jib, pan & tilt • World scale 1:1 / 1:2 / 1:4 — shoot your set like a miniature for drone-style moves • Works offline too: AR demo scene + local take recording, no account needed GREYSET is built for filmmakers, DOPs and AI-video creators who want real camera language — not prompt roulette.
