7:02 AM. You haven't said a word yet. "Morning. Rain clears by nine. Your ten o'clock moved to ten thirty — and that form you've been dodging is due today, so I put it at the top of your list." Every assistant until now has waited to be asked. Orb doesn't wait. IT KNOWS WHAT'S UP Orb keeps a running sense of your day and reaches out when something actually matters: "You've got four commits sitting unpushed since Tuesday. Worth protecting before the weekend." "NVDA's up four percent since you asked me to watch it." "You've been at this for twenty hours. I moved tomorrow's first ping to ten so you can sleep in." And when nothing matters? Silence. The bar for interrupting you is high. YOUR COMPUTER, IN YOUR POCKET Run the free, open-source Orb server on your own computer and your phone becomes its remote. Ask for real work from anywhere — "clean up my downloads folder" — and carry on with your day until the receipt lands: "Done. 214 files sorted, three gigs freed." Your machine did the work. Your phone just told you. JUST SAY IT Voice-first, human answers. "Remind me at eight" — "Done, eight tonight." No menus, no forms, no robot voice reading bullet points. IT REMEMBERS What you said last week. What you asked it never to let you skip. Where you left off. One continuous assistant across voice and chat — whichever AI engine you plug in, Orb stays Orb. ACTUALLY YOURS No account. No developer cloud — we couldn't read your data if we wanted to, because there's nothing of ours to read it with. Choose which AI powers it, swap anytime, name it what you like. Self-host and nothing ever leaves hardware you own. You've been promised this assistant for fifteen years. Nobody built it, because it can't be built in someone else's cloud — an assistant this close to your life only works if it's yours.

Transform ideas into manufacturing-ready CAD models using plain English. AiCADGen uses AI to generate 3D models, engineering drawings, and manufacturing files from simple text descriptions, sketches, technical drawings, or reference images. Whether you're prototyping a product, designing a mechanical part, or creating a custom component for 3D printing or fabrication, AiCADGen helps you move from concept to CAD in minutes instead of hours. Perfect for engineers, designers, makers, students, inventors, manufacturers, and anyone who needs professional CAD files without spending hours modelling. FEATURES • Generate 3D CAD models from text prompts • Convert sketches, photos, and technical drawings into editable CAD • Create dimensioned engineering drawings automatically • Export STL, STEP, DXF, PDF, SVG, OBJ and more • Interactive 3D model viewer with zoom, rotate and inspect controls • AI-assisted design refinement through natural conversation • Parametric geometry generation • Fast concept iteration and design exploration • Generate printable models for 3D printing • Produce files suitable for CNC machining, laser cutting and manufacturing workflows • Cloud-based projects available across your devices CREATE FROM NATURAL LANGUAGE Describe your design as you would explain it to another engineer. Specify dimensions, materials, wall thickness, tolerances, hole sizes, mounting points, threads, clearances, manufacturing processes, or design intent. The more detail you provide, the better the generated result. IMPORT REFERENCE IMAGES Upload hand sketches, whiteboard drawings, screenshots, existing technical drawings, product photos, or concept artwork. AiCADGen analyses your references and uses them together with your instructions to generate accurate CAD models and engineering drawings. EXPORT FOR YOUR WORKFLOW Generate the formats your workflow requires. • STL for 3D printing • STEP for professional CAD software • DXF for CNC machining and laser cutting • PDF engineering drawings • SVG vector files • OBJ and additional 3D formats BUILT FOR • Mechanical engineering • Product design • Industrial design • Manufacturing • 3D printing • CNC machining • Laser cutting • Sheet metal concepts • Prototype development • Education • DIY and maker projects WHY AICADGEN Traditional CAD modelling can take hours for even simple concepts. AiCADGen accelerates early-stage design by generating models and drawings from natural language, allowing you to explore ideas, iterate quickly, and prepare files for manufacturing workflows faster. Whether you're creating brackets, enclosures, adapters, fixtures, storage systems, machine components, workshop tools, furniture parts, or custom mechanical assemblies, AiCADGen helps turn concepts into CAD-ready designs. GET STARTED Every new account includes credits to explore the AiCADGen workflow. Generate your first designs, inspect the interactive 3D model, and review engineering drawings before choosing the option that best suits your projects. When you're ready, unlock exports through a subscription or a one-time design unlock. GOOD TO KNOW AiCADGen is a design and drafting accelerator, not a replacement for professional engineering review. Generated models and drawings should always be verified before manufacturing, fabrication, installation, or safety-critical use. SUBSCRIPTIONS Choose the plan that fits your workflow. Paid plans include commercial use and CAD file exports, while higher tiers provide faster generation, higher-quality results, priority processing, team features, and API access. Individual design export unlocks are also available, and purchased credits stay on your account until you use them. Subscriptions renew automatically each month unless canceled at least 24 hours before the period ends. Manage or cancel in your App Store settings.

Verdict
The clearest difference is in-app purchases: Orb at none against AiCadGen's 9. Orb also leads on update cadence (every 5 days vs every 2 weeks). AiCadGen's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
