About Decoding

This decoding calculator is a modern React refresh of an existing calculator project cloned from GitHub.

Decoding Studio expands the calculator with a workspace where decoders can organize their research, build visual presentations, and prepare completed work for publication.

In development: Planned Algorand features will let creators mint completed publications as NFTs and offer them for sale to their communities.
