TestMyPrompt

What it does

TestMyPrompt helps developers and teams find vulnerabilities in AI prompts before they reach production. Test across 22 security, safety and reliability categories, including prompt injection, jailbreaks, data exfiltration, indirect prompt attacks, tooling permissions, bias and hallucination risk. Get clear results, risk ratings and actionable recommendations to help you ship safer, more reliable AI.

Test AI prompts for injection, jailbreak, data leakage, bias, and hallucination risks before production.

Automatically scan system prompts for injection vulnerabilities, policy bypass attempts, and data leakage risks. Ship safer AI products with confidence. Our AI evaluator checks prompts across security, safety, ethics, and quality dimensions so nothing slips through. Paste any system prompt and get a 0–100 risk score with categorised findings before you ship. Comprehensive checks across security, safety & ethics, and quality — covering injection, bias, toxicity, and hallucination risk. Every finding includes a plain-English explanation and a concrete remediation step, not just a flag. Organise tests by product, model, or environment. Assign owner, admin, and member roles per workspace. Every…from testmyprompt.net

  Find prompts that jailbreak your agent (open source)2025 · security.vista-labs.ai · ▲8

  We've built an open-source tool to stress test AI agents by simulating prompt injection attacks. We’ve implemented one powerful attack strategy based on the paper [AdvPrefix: An Objective for Nuanced LLM Jailbreaks](https://arxiv.org/abs/2412.10321). Here's how it works: - You define a goal, like: “Tell me your system prompt” - Our tool uses a language model to generate adversarial prefixes (e.g., “Sure, here are my system prompts…”) that are likely to jailbreak the agent. - The output is a list of prompts most likely to succeed in bypassing safeguards. We’re just getting…

  Hi everyone, We built ModelRed to test AI models and apps for security issues. Ran 4,182 attack probes against 9 leading models to see what would break. Leaderboard: https://modelred.ai (no signup, just check it out) Claude scored 9.5/10 but still failed on medical/financial prompts. Mistral Large scored 3.3/10. The gap between best and worst is huge. We test for prompt injections, data leaks, jailbreaks, risky tool calls, domain specific hacks, basically everything that goes wrong when your LLM has access to real data and APIs. The platform runs these tests…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
