Hey Product Hunt! 👋 I'm Ian, founder of SafePrompt. A bit of context on why I built this: After spending 15 years as an architect at eBay, I started building AI-powered apps — and I was shocked by how easy it is to attack them. Prompt injection lets anyone type "Ignore all previous instructions" into your chatbot and completely hijack it. It's been used to steal data, bypass safety filters, and manipulate AI agents. I looked for an API to detect it. Lakera costs enterprise prices and requires a sales call. Building it yourself takes weeks and still misses attacks. So I built SafePrompt: → Add one API call before your AI processes user input → Detects injection attempts in under 100ms → Free tier with 1,000 requests/month (no credit card) → Works with any LLM: ChatGPT, Claude, Gemini, Llama I'd love to hear: Are you building AI apps? How are you handling security today? Happy to answer any technical questions below! 🔒
