Originally I set out to build a monetized version of OpenAI’s custom GPTs, where developers would earn money when users used their custom GPT. Eventually this evolved into a platform for AI powered apps, which expose not only context and capabilities to an LLM but also a UI to a human user.
Magic Sandbox apps execute in a strictly sandboxed iframe and communicate via postMessage to request to persist data or hit backend endpoints (what I call Functions), among other capabilities. Because Magic Sandbox provides the AI assistant and handles auth, persisting data, and payments, building apps is super easy - it’s a great platform for publishing (and monetizing!) your vibe coded apps.
Apps can expose a context function which is called when the user chats with their AI assistant with the app open - the context function returns a string which is added to the LLM’s prompt. Apps can also expose an API of functions that the assistant can call to fulfill the user’s request, or the assistant can generate arbitrary code to execute in the app’s sandbox.
I’d love to hear your thoughts and feedback - thanks in advance!
