Syntix is an AI code interpreter. It allows you to ask an AI programming questions, and have it answer back in one of 8 languages: JavaScript, TypeScript, Python, C#, Java, Go, Rust, pgSQL. The AI will automatically install any needed dependencies and execute the generated code in its own environment - with full internet access. This gives the AI instant feedback on its code, circumventing hallucinations.

You can also upload files and folders to the execution environment for processing. The current size limit is about 7GB.

I use fly.io's Fly Machines for the execution environments, as well as for the app's back-end.
