Overview

LochBot is a free checker for chatbot builders that reads your system prompt and looks for structural patterns linked to 31 kinds of prompt injection attack in seven groups. It gives a score out of 100, a letter grade and a suggested fix for each weak spot. It is a heuristic checker: it inspects the text of the prompt and does not run attacks against a real AI model. The analysis runs in your browser, so the prompt is not uploaded.
