Overview
Image Upscaler 4K is a dual-engine AI image upscaling platform that lets you enlarge images to 4K resolution in seconds. It offers a fast mode (Recraft Crisp) for quick batch processing and a pro mode with five specialized Topaz AI models for portraits, product photos, old prints, documents, and AI-generated art. Users can adjust sharpness, noise reduction, and face enhancement. Pricing is credit-based with annual subscriptions.
Wirable tests whether AI agents can actually use your product. You paste a URL, and three AI agents run a live browser audit, scoring your product from 0 to 100 across six dimensions (API surface, auth, MCP, errors, idempotency, docs). If agents get stuck, Wirable hosts an MCP proxy in front of your product so they can complete the job without you shipping code. The audit is free; the hosted proxy and drift monitoring cost $29/month.
