Can you vibecode this?

Yes

The core loop — take text input, rewrite it via an LLM with mode-specific prompting, return humanized output — is straightforward to build. The writing modes and Basic/Stealth depth are prompt engineering. The image and AI detectors add surface area but are each self-contained features.
