Merlin brings the most capable AI models together in one app. Ask questions, research any topic, work through your files, and create images and videos, all from a single chat. Many models, one app Choose from a wide range of leading AI models for writing, coding, reasoning, and quick answers, or turn on Magic and let Merlin pick the right model for each message. Research with sources Merlin can search the web as it answers and shows the sources it used, so you can check where every answer comes from. For bigger questions, deep research gathers and summarizes information into a full report. Chat with your files and photos Snap a photo, pick from your library, or upload a document and ask Merlin about it. Everything you upload is kept in your Vault, ready to reuse in any chat. Create images and videos Generate and edit images, and turn your ideas into short videos with optional audio. Choose the duration and aspect ratio, then save or share the result. Crafts Ask for code, a diagram, a web page, or a small interactive app, and Merlin builds it as a Craft you can preview right in the chat and share with a link. Projects Organize related chats into projects, add files as project knowledge so Merlin keeps the context, and invite others to view or edit with you. Made for your phone - Dictate your messages instead of typing - Get answers in the language you prefer - Light and dark appearance - Share chats with a link Start for free with daily queries. Upgrade to Merlin Pro for higher limits and access to Pro models. AI responses can be inaccurate. Check important information before relying on it.

3D models straight from your iPhone – no cloud, no subscription. Photograph, compute, export. For any object you can hold. ObjectForge turns your iPhone into a capable 3D scanner. Figurines, tools, jewel- lery, design models, prototypes – anything you can hold in your hand can become a print-ready or CAD-ready 3D model. All on-device, no cloud, no subscription. HOW IT WORKS Using Apple's Object Capture technology, you photograph an object from multiple angles. PartScan then computes a high-resolution, textured 3D model directly on your iPhone. No server. No waiting. REFINE YOUR MODEL The built-in editor lets you smooth surfaces, close gaps in the mesh and correct the texture exposure – all non-destructively. Edits are always saved as a new copy; the original scan is never overwritten. EXPORT READY FOR CAD Export finished models in three formats: • STL – straight into your 3D printer or slicer • STEP (AP214) – for CAD applications such as Fusion 360 or FreeCAD • USDZ – for AR preview and sharing with other Apple devices The export unit (mm, cm, inch) can be set freely in Settings. STEP is always written in millimetres, following the CAD standard. TIPS FOR BEST RESULTS Matte, textured surfaces work best. Use even, diffuse lighting and move slowly around the object in overlapping passes from multiple heights. Shiny, reflective or uniformly smooth objects are more difficult to capture accurately. REQUIREMENTS VORAUSSETZUNGEN: Only devices with LiDAR Scanner are supported! iPhone (only Pro-models): iPhone 12 Pro / Pro Max, 13 Pro / Pro Max, 14 Pro / Pro Max, 15 Pro / Pro Max, 16 Pro / Pro Max, 17 Pro / Pro Max iPad Pro with M1 or later: iPad Pro 2021 (M1), 2022 (M2), 2024 (M4), 2025 (M5) All processing runs locally on your device. No user data is transmitted or stored externally.
