Marnix - AI appbuilder
Create Apps with your Voice
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Just shipped: Lock Screen Live Activities, Dynamic Island progress, and voice huddles in 10 languages. Try it free with 300 credits on signup.
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.
