Protect your AI applications from prompt injection, jailbreaks, and data leaks. One API call. Works everywhere.
ML-powered protection against prompt injection, jailbreaks, and data leaks. One API call. Works everywhere. Detect and block injection attacks that attempt to override AI instructions or extract sensitive information. Stop jailbreak attempts that try to bypass AI safety measures and content policies. Auto-detect and encrypt sensitive data like SSNs, credit cards, and emails before they reach the AI. Detect attacks in 12+ languages including Spanish, French, Chinese, Japanese, Korean, Arabic, and more. OCR-powered detection of prompt injections hidden in images. Protect against visual attacks. Advanced machine learning models trained on 589K+ real attack samples with 99.65% accuracy. Help us…from preempt-ai.vercel.app

PromptGuardDec 2025 · promptguard.co · ▲3Every other gateway is detect-and-block. You don't get a security grade. You don't get red team in CI. We built the one that does. PromptGuard is a proxy: change your base URL (one line with our SDK, or a few lines without), and every request gets checked for prompt injection, PII leaks, jailbreaks, and abuse. 20+ threat vectors, 39+ PII types. We also ship a red team suite and an autonomous agent that mutates attacks to find bypasses - you get a grade (A-F) and a GitHub Action that runs these tests on every PR. So you see where you're weak before you ship. Works with OpenAI, Anthropic,…

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…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
