Keep ChatGPT inside the rules you already approved.

Write 3–10 hard project rules once. Governor protects each new prompt, checks the completed answer, and puts PASS, BLOCK, or NOT ENOUGH DATA beside it.

No card for the beta. Continue after seven days for $12/month. Checkout will open only when paid access is launched.

In the frozen v0.2 evaluation: 5 violations in 24 unprotected responses, 0 in 24 protected responses; all 5 bad proposals were stopped. v0.3 changes the workflow and still needs its own user pilot.

Install and start

1. Download and extract the extension.
2. Open chrome://extensions, turn on Developer mode, choose Load unpacked, and select the extracted folder.
3. Open Governor, name one project, and enter 3–10 rules such as “Do not use Firebase”, “Budget must be at most 500 USD”, or “Storage must be local”.
4. Use ChatGPT normally. Governor checks the next completed answer automatically.

What it checks

v0.3 supports forbidden choices, required exact values, and numeric maximums. It checks the structured result and independently scans the answer text. A rule it cannot formalize must be rewritten before saving. Governor does not inspect executed code or actions outside the displayed answer.

Private by default

Rules, conversations and answers stay between your browser and ChatGPT. Governor stores project rules and results locally. Anonymous outcome counts are shared only if you select that option. Paid access uses a random installation identifier with no email or conversation content.
