README

<h1>nixie</h1>

A personal assistant platform that its owner runs and controls: every rule readable and editable, every decision recorded, and personal data kept on the owner's own hosts.

Status

nixie is in Phase 2, Research, and has no product code. The work runs in 4 phases: brainstorm, research, design, and decide. Decisions are recorded as research settles each question.

Checks

bun install
bun run check        # format, lint, and the prose check

Layout

  • docs/ holds the overview, the principles, the scope, the decision records, and the designs for what is not built yet. Start with the overview.
  • spikes/ holds throwaway experiments that answer research questions.
