SafePrompt is an API service that detects and blocks prompt injection attacks in AI-powered applications. It provides fast, accurate validation of user inputs, integrates easily via API or Chrome extension, and is designed for developers building secure AI apps.
LaunchPromptly is a runtime safety and security platform for LLM-powered applications. It offers multiple defense layers, including detection, red teaming, context analysis, and response judgment, accessible via a client-side SDK and API. Designed for developers integrating LLMs, it helps ensure safe and compliant AI deployments.
PromptShield is a real-time API designed to protect large language model (LLM) applications from prompt injection attacks. It analyzes every user input and blocks malicious prompts before they reach the LLM, aiming to prevent exploits such as jailbreaks, system prompt leaks, and adversarial manipulations. The service targets developers and teams building AI-powered systems that require robust security against a wide range of prompt-based threats. The platform detects and blocks over 12 attack vectors, including jailbreaks (such as DAN, AIM, Developer Mode, and hundreds of known templates), prompt extraction attempts, role hijacking, indirect injection from external content, context manipulation, and data exfiltration. For each input, PromptShield provides a verdict (BLOCKED, SUSPICIOUS, or SAFE), a risk score, an explanation, and recommendations, all with an average latency under 200 milliseconds. The API can be integrated with a single HTTP request, and a Python SDK is available for streamlined setup, allowing developers to check if user messages are safe or obtain detailed scan results for further analysis and logging. PromptShield is delivered as a cloud-based REST API, with integration requiring only an API key and minimal setup. The service offers a live demo for real-time prompt analysis without signup and provides Swagger documentation for developers. Audit logs, custom rule sets, real-time alerts via webhooks, and dedicated support are available on higher-tier plans. For enterprises with strict compliance or deployment requirements, on-premise options, SOC 2 readiness, custom ML model tuning, and white-labeling are offered. Pricing includes a free tier with 50 API calls per month for developers and side projects, a Pro plan at $99 per month with 25,000 calls, a Business plan at $499 per month with 500,000 calls, and custom enterprise solutions with unlimited usage and additional compliance features. No credit card or forms are required to access the free tier, and users can obtain an API key instantly with just an email address.
