What it does
DevHelper is a free, local-first desktop app for builders. Its headline feature is Sketchly AI: describe an app, get a wireframe, theme it from a brand brief, generate a Codex-ready project plan, then click 'Code it' and OpenAI Codex writes the starter repo. AI is funded by community donations — every donation tops up DevHelper tokens spendable across every AI feature. Also includes Mermaid flowcharts, a dev-news reader, Claude + ChatGPT usage trays, and an extension marketplace.
