Type in a salary and watch it arrive, second by second — with federal tax, state tax, Social Security and Medicare taking their share in streams beside it.
Everything runs in your browser. Nothing you type is sent anywhere.
Status: v1 (the salary stream, in River and Arcade skins, installable) is built; the
latest deploy is at https://paystream.bitcopia.workers.dev. See
docs/PRODUCT_BRIEF.md and the phased plan in
docs/ENGINEERING_SPEC.md.
