Build your app from ChatGPT, Claude or Claude Code

MCP (Model Context Protocol) is a standard way for an AI assistant to use another service's tools. Once you connect Corenna and sign in, your assistant can do the same things you do on corenna.dev, for your account only, and tell you what happened in the chat.

Nothing is installed in your repo or on your computer for this. You paste one web address into your assistant's settings and sign in with your Corenna account.

From one message, an assistant can take a repo all the way to an app file:

1. Add your GitHub repo as a Corenna project, filling in the app name, app ID and framework.
2. Run the pre-build check and tell you what would stop the build, and how to fix it.
3. Create the Android signing key for a new project.
4. Start the build and keep an eye on it until it finishes.
5. If it fails, read the build log and explain the cause.
6. When it succeeds, give you a download link for the .apk, .aab or .ipa.

With Claude Code, which works on the code on your computer, the assistant can also fix a problem in your repo, push it, and build again until the app comes out.

Some things are deliberately left to you, on corenna.dev:

• Signing passwords. When the assistant creates your Android key, it sends you a link to the project's Signing tab to save the passwords there. They are never shown in the chat.
• Apple files. Your iOS certificate and provisioning profile are uploaded on the Signing tab by you. Your assistant will never ask you to paste them.
• Installing the GitHub App. The first time, your assistant gives you a link to let Corenna reach the repo. You click it and pick the repo.
• Payment. If a build needs a plan, the assistant sends you the pricing page. It can't pay for you.

Your assistant signs in as you, so it sees your projects and builds and nobody else's. Every request goes through the same checks as the website. And because Corenna is zero clone, connecting an assistant doesn't put your source code anywhere new: builds still run inside your GitHub repo.

• Claude (web, desktop or phone app): add Corenna as a custom connector once and use it in any chat.
• ChatGPT: add Corenna as a connector in developer mode.
• Claude Code: one terminal command. Best when your app's code is on your computer, because it can fix and push changes itself.

The step-by-step setup for all three, with the exact settings to choose, is in How to connect your AI assistant.

Once connected, start a new chat and ask:

Use Corenna to turn https://github.com/your-name/your-app into an Android app I can install on my phone. Tell me anything I need to do, and give me the download link when it's done.

Say "for Google Play" if you want the .aab to upload to the store. Your first month of Corenna is $1.
