What is Agent C?
Agent C is an AI design tool that turns raw app screenshots into finished App Store screenshot sets, built for developers who need store creative that converts without a designer. It uses Claude to analyze your screenshots and generate a complete set, including headlines derived from your real app data, then lets you change any headline, screenshot, or layout from a simple panel rather than dragging elements around. You can open a set with a hand-held phone display, an app icon with feature tags, or lifestyle photography, and it adds smart UI close-ups that highlight the relevant interface element. Exports are exact-pixel PNGs for every required size, including 6.9-inch, 6.5-inch, and iPad 13-inch, plus matching product-page headers and search-result images. An optional App Store Connect API integration uploads directly, and an MCP server lets AI agents such as Claude Code drive it. For teams running Apple Search Ads, where the screenshot is the primary creative, it targets conversion specifically. For anyone comparing the best AI for App Store screenshots, Agent C is the design-focused option listed under AI design tools on BestAIFor.
