Works on: ChatGPT · Google Gemini · Claude prompt validation · Microsoft Copilot What it does Verify LLM inputs before sending — Pre-flight check on audience, dates, metrics, and scope. Lock meaning before the model runs. Preview without sending — Paste a prompt in the side panel; see what would be flagged. No message sent to the chat. Compare vague vs locked replies — Reply A (sent as-is) vs Reply B (after you confirmed facts). See what the model invented when you were vague.
