Web and mobile apps,
with AI built in.

mi9 is a software studio in New York. We build web and mobile apps and the AI that runs inside them: RAG pipelines, chatbots and agents that work with your own data.

THE APP, LAYER BY LAYER
A browser window and a phone, each taken apart into its layers: the frame, the layout grid, the content and the controls. A data layer appears underneath, then an AI between the data and both apps, and its answers arrive in the browser and the phone.

Questions

01What does mi9 build?

Web apps, mobile apps, and the AI inside them. On the web that means marketing sites, dashboards and full products. On mobile it means iOS and Android apps built with Expo. For AI it means chatbots that answer from your own documents, agents that carry out tasks, and automation of repetitive work.

02How much does a project cost?

It depends on the scope. Tell us what you need, we talk it through on a call, and you get a price in writing.

03How long does a project take?

Small sites take weeks and full products take months. You get a timeline in writing before work starts.

04Can you add AI to an app we already have?

Yes. We work with existing codebases and add search, chat or automation to what you already run, usually without rewriting it.

05Where does our data go?

It stays in your systems wherever possible. Before we build anything we tell you which model providers and services a feature would use, and you approve them.

06Who owns the code?

You do. It lives in your repository from the first day.

07Do you work outside New York?

Yes. We are based in New York and work remotely with clients across the US.
