Minimax‑TD Voting App

Create an election, collect ranked ballots, and compute Minimax‑TD results—shareable via a single link (no server required).
Ready

Election setup

Tip: keep candidate names short (e.g., “A”, “B”, or “Smith”). You can reorder them later for ballot entry.
    Reorder candidates by dragging the handle (≡). This does not affect results; it just changes the default ballot order.

    Cast a ballot

    Drag candidates to rank them from #1 (top) to last. Then click Add ballot. You can add multiple ballots (e.g., one per voter).

    Privacy: ballots are stored in your browser (localStorage). Hosting this page creates a public link, but it does not send ballots to a server.
      0 ballots stored

      Bulk import ballots

      Paste ballots (one per line). Format: A>B>C. Names must match candidates exactly.

      Results

      Add candidates and ballots, then click Compute results.

      Pairwise matrix

      Compute results to view pairwise comparisons.

      You can export ballots for analysis or verification.
      Want “real” public voting?
      This app is static (no backend). For a public election where each voter’s ballot is stored remotely and results update live, you’ll add a backend (e.g., Supabase/Firebase) and require unique voting links.
      Note: ballots are not included in the share link—only the election setup.
      Method: Minimax‑TD (loss‑vector lexicographic minimization)
