LochBot Review

lochbot.com →

LochBot is a browser-based prompt injection vulnerability checker that scores chatbot system prompts against 31 known attack patterns across 7 categories.

Chat Frontends & Clients

Verdict

LochBot fills a practical niche for developers building AI-powered chatbots who want a fast, zero-setup security audit of their system prompts. It runs entirely client-side — your prompt never leaves the browser — and produces a 0-100 score with letter grade, per-vulnerability severity ratings, and copy-paste fix suggestions. The core limitation is by design: it performs static pattern matching on prompt text, not dynamic testing against a live model, so it cannot catch runtime jailbreaks that bypass defensive language.

What it does

Analyze your system prompt for injection vulnerabilities. 31 attack patterns, 7 categories, instant scoring.

Best for

Security engineers, developers, and product teams building AI-powered chatbots, particularly those in regulated industries.
