Build apps with
your voice

Describe what you want in plain English. No code, no jargon, no learning curve. Just talk, and Mulu builds it for you in real time.

Talk naturally. Build effortlessly.

Mulu understands you the way a teammate would. No special syntax, no commands to memorize.

Natural speech recognition

Speak the way you normally would. Mulu uses advanced speech-to-text to understand your intent, not just your words.

Real-time conversation

Have a back-and-forth dialogue with AI. Ask questions, give feedback, and iterate on your app as you go.

Multi-language support

Speak in English, Spanish, French, and more. Mulu recognizes your language and responds accordingly.

No coding terminology

You never need to say "div", "component", or "API". Just describe what you want in everyday language.

Voice + text hybrid

Switch seamlessly between voice and typing. Start a request by talking, then fine-tune it with text. Or vice versa.

Hands-free building

Walk around, sketch on a whiteboard, or relax on the couch. Build your app without touching a keyboard.

How voice building works

Three simple steps from idea to working app. No setup, no tutorials, no documentation to read.

1

Speak your idea

Press the mic button and describe what you want. "Build me a fitness tracker with a workout log and progress charts."

2

AI understands intent

Mulu's AI parses your natural language, understands the structure, design, and functionality you're describing.

3

App builds in real-time

Watch your app materialize in the live preview. See every change as it happens and refine with more voice commands.

What people are building with voice

From personal tools to small business apps, voice building unlocks creativity for everyone.

Booking & scheduling

Online storefronts

"Build a simple store for my candle business with product photos, prices, and a checkout page."

Common questions

Everything you want to know about building apps with your voice.

Do I need a good microphone?

No. The built-in microphone on your laptop works fine. Mulu uses noise-cancelling speech recognition that works in normal environments - offices, cafes, even with background music.

What if the AI misunderstands me?

Just tell it. Say "that's not what I meant" or "undo that" and explain what you actually wanted. Mulu treats voice building as a conversation, so you can always correct course naturally.

Can I switch between voice and typing?

Absolutely. Start a request by voice, then refine details by typing. Or type your main request and use voice for quick follow-ups. Both inputs work seamlessly together.

Is there a limit on how long I can talk?

No hard limit. Mulu processes your speech in real time, so you can speak for as long as you need to describe complex features. For best results, break big ideas into smaller requests.

What languages can I speak in?

Mulu supports 50+ languages including English, Spanish, French, German, Portuguese, Japanese, Korean, Chinese, Arabic, Hindi, and many more. The AI responds in whatever language you use.

Can voice building create complex apps?

Yes. Voice building is backed by the same AI that powers text-based building. You can create multi-page apps with forms, databases, authentication, payments, and more - all by describing what you need.
