It is not compatible with Intel-based Macs or older versions of macOS, as it relies on the specific architecture and frameworks available on the latest Apple Silicon platforms.

Privacy is foundational to Bantr's design. Since all processing is done locally, your text input is never transmitted over the internet to external servers.
