Quap documentation
Everything Quap does, how to use it, and what Pro adds.
Quap is a desktop workbench for structured data on macOS and Windows. Open or paste JSON, YAML, XML, CSV, SQL, Markdown and more; read it as a tree, graph, table or chart; clean, convert, transform and encrypt it; and ask the AI assistant to do multi-step jobs for you. Everything runs on your computer.


Local-first
Your documents never leave your computer. Quap has no analytics. The AI assistant sends only your instruction (and, if you allow it, key names) to the provider you choose — or nothing at all with the built-in local model.
