What Adamant AI Spreadsheet Agent is
Adamant AI Spreadsheet Agent is a free alpha standalone app for building and analyzing spreadsheets, as well as working with tabular data. It runs on Windows 10 or later and macOS 26 or later. In its local runtime, prompts and files stay on the device, and the app can work without an internet connection. A separate cloud runtime is optional; the maker describes it as using zero-retention infrastructure with no profiling.
