Overview
blurmyplate is a specialized privacy tool for car sellers and photographers. It automatically detects and blurs license plates in car photos before they are published online. The service is designed for private vehicle sellers, small dealerships, and marketplace sellers who need clean, listing-ready images without exposing sensitive plate details. It offers a simple drag-and-drop interface, supports JPG, PNG, and HEIC formats, and ensures privacy through encryption, EXIF stripping, and automatic deletion after 30 days.
AIQualityHQ is a free, browser-native toolkit for AI developers, QA teams, and prompt engineers. It provides a suite of seven tools, including a Prompt Quality Checker, Prompt Rewriter & Compiler, AI System Prompt Generator, Length & Token Optimizer, Prompt Injection Scanner, AI Jailbreak Detector, and AI Visibility & LLM Auditor. The engine is deterministic and runs entirely client-side, ensuring 100% privacy and instant results in under 10ms. It scores prompts across six dimensions: structure, memory, context, accuracy, privacy, and security.

Pricing
blurmyplate operates on a freemium model. The first three photos are free, with no account required and no watermark. For additional photos, users purchase credit packs, which are valid for one year. Failed auto-detections do not consume credits, and one-off unlocks are available for casual users. This makes it cost-effective for occasional sellers but potentially expensive for high-volume dealers.
AIQualityHQ is entirely free. There are no subscription fees, no API keys, and no sign-up requirements. All seven tools are accessible without cost, making it an attractive option for developers and QA teams with budget constraints. The lack of server-side processing also eliminates any per-token costs.
