Marnix is your AI CTO. Describe an app out loud and our build cloud writes it for you — code, design, and a live URL, streamed back to your phone in real time. No syntax. No setup. No second laptop. Just talk it through. ——————————— HOW IT WORKS ——————————— 1. Open a huddle on your phone and talk it through — or type a prompt. 2. Your idea is sent securely to our build cloud, where our AI plans your app, writes the code, and starts shipping it. 3. The result streams back to your phone live as it's built. Iterate by voice or text — "add Stripe", "darker header" — until it's exactly right. 4. Publish it to a real, live URL. Marnix requires an internet connection — all generation happens on our servers, not on your device. ——————————— WHAT YOU CAN BUILD ——————————— Landing pages. Dashboards. Internal tools. Travel planners. Habit trackers. Pricing pages. Investor briefs. CRM screens. Booking flows. Side-project ideas you've been sitting on for months. If you can describe it, Marnix can build it. ——————————— FEATURES ——————————— • Voice huddles — talk through an idea in real time, Marnix talks back • Live preview streaming — watch the build progress on your phone as our cloud writes it • Iterate by voice — "make the header darker, add a search bar, connect Stripe" • 10 voice languages — English, Dutch, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean • Connect Stripe, Supabase, GitHub and 98+ services without leaving the huddle • Publish to yourname.marnix.ai instantly — free, with HTTPS • Bring your own custom domain • Big-screen mode — beam any project to your laptop or TV by scanning a QR code • 10 hand-painted city themes — Tokyo, Paris, Amsterdam, Seoul, New York, San Francisco, London, Silicon Valley, Spaceport, and more • Matching app icons for every theme • Live Activities + Dynamic Island — track your build from the Lock Screen while you do other things • Native iPad support • Dark mode throughout ——————————— START FREE ——————————— Every new account gets 300 free credits — enough to build, iterate, and ship a real app before deciding whether to upgrade. ——————————— MARNIX PRO ——————————— For makers who ship daily. Higher credit limits, custom domains, priority cloud generation, advanced models. ——————————— MARNIX BUSINESS ——————————— For founders and small teams. Higher iteration limits, fastest cloud generations, team workspace, priority support. ——————————— SUBSCRIPTION TERMS ——————————— • Marnix Pro and Marnix Business are auto-renewing subscriptions offered monthly or annually. • Payment is charged to your Apple ID at confirmation of purchase. • Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. • Manage or cancel anytime in Settings → [Your Name] → Subscriptions. • Any unused portion of a free trial is forfeited when you purchase a subscription. ——————————— PRIVACY ——————————— Marnix processes your prompts and project data on our secure servers in order to build your app. We don't train AI models on your work, and you can delete your projects at any time.
