Score: 6.0/10 (Innovation: 4, Technical: 7, Documentation: 9, Utility: 4)

PromptPad is a native C++20/Qt6 desktop editor specifically built for writing long prompts for AI coding tools like Codex and Claude Code. It emphasizes local-first plain-text editing with Scintilla, SQLite-backed drafts/templates, and an external-editor hand-off mode, avoiding any network calls or AI integration. The project is technically polished and well-documented but addresses a narrow niche that may not justify a dedicated application for most developers.

Target audience: AI developers and prompt engineers
