Go from idea to functional prototype with AI – in minutes

AI prototyping is the process of turning an idea into a working, interactive preview of your app or website – using AI to handle the design, layout, and functionality for you. Instead of spending weeks in design tools or waiting for a developer, you simply describe what you want and AI builds it in minutes. With Horizons, your prototype isn't just a mockup – it's a functional, shareable preview you can test and refine before committing to full development.

Anyone who has an idea they want to visualize, test, or share before committing to full development. This includes:

• Founders and entrepreneurs – validate your concept with investors or early users before spending on development.
• Product managers – turn requirements into interactive prototypes to align stakeholders and reduce revision rounds.
• Freelancers and agencies – show clients exactly how their project will look and work before building it.
• Designers – bring concepts to life without waiting for a developer.
• Anyone with an idea – if you can describe it, Horizons can build it.

No design skills, no coding knowledge, and no technical background required.

A wireframe is a basic visual blueprint – it shows the structure and layout of a page without any styling or interactivity. A prototype goes further – it looks and feels like the real thing, with working interactions, real content, and a functional design. With Horizons, you skip the wireframe stage entirely and go straight to a fully interactive prototype, just by describing what you need.

A prototype and an MVP (Minimum Viable Product) are often confused but they serve different purposes.

A prototype is about visualization and validation – it's an interactive preview of your idea that you share with stakeholders, investors, or users to gather feedback before committing to full development. It doesn't need to be fully functional or ready for public use.

An MVP is your first real, working version of the product – built with just enough features to launch, acquire early users, and start learning from real usage.

In short: you prototype to validate your idea, and you build an MVP to test it in the real world. With Horizons, you can do both – start with a prototype, gather feedback, and scale it into a fully functional product without starting from scratch. Learn more in our prototype vs MVP guide.

None at all. Horizons uses a conversational approach to building – often called vibe coding. You simply describe what you want in plain language and AI builds it for you in real time. Want to adjust the layout? Just ask. Need to change a user flow? Describe it. If you're new to the concept, our vibe coding guide walks you through everything you need to know.

Once your prototype is ready, you can publish it and share it via a link with anyone – stakeholders, investors, clients, or test users. They can interact with it directly, and you can keep refining it based on their feedback by simply chatting with Horizons.

Yes – and this is where Horizons stands out from traditional prototyping tools. When you're ready to go beyond prototyping, simply publish your project as a fully live website or app with one click. Hosting, domain, and business email are all included in your plan.

And because Horizons comes with an integrated backend built in, your prototype already has databases, user accounts, and file storage ready to go – so when you're ready to scale, everything you need is already there. No rebuilding from scratch, no external tools needed.

You can start for free – no credit card required. Once you're in, you'll get 5 AI credits to start building right away. Each credit equals one prompt, so you can describe your prototype, tweak it, and see it come to life before committing to anything. When you're ready to publish, simply switch to one of our paid plans. Hosting and domain are already included – just hit publish and your prototype goes live.
