Proving
Proving you wrote code with AI assistance. Cryptographic signatures for IDE-generated code to demonstrate human involvement.
The Pain Point
You use GitHub Copilot or Cursor. You write 80% of the architecture, but specific blocks are just "Tab" completions.
To the world (and your boss/professor), it all looks the same.
- Problem: If you can't prove which parts you thought of, you risk being labeled "just a prompter."
- Risk: Compliance teams might ban AI tools entirely because they can't distinguish "safe human code" from "AI hallucination."
The Solution: "Ghost Signatures" (Your Typing Fingerprint)
The system works inside your IDE (VS Code/Cursor) and watches how code appears:
- Human Mode: You type at 40-100 words per minute. You backspace. You pause to think.
- Coding Assistant Mode: Code appears instantly (1000+ chars in 10ms) or via "Tab" acceptance.
It creates a signed map of your file:
> "Lines 1-20: Human Authored (99% confidence)"
> "Lines 21-30: AI Generated (Copilot)"
Why It Matters
- Credit: Prove you did the heavy lifting. "I designed the logic; AI just typed it."
- Safety: Reviewers can focus their energy on the AI-generated parts (which might be buggy) and trust the human parts.
