What is Polyteller?

Polyteller adds small workflow controls directly to the Polymarket browsing experience. Its main functions address timing and accidental disclosure: show an event end time in your local zone, schedule reminders and mask balances before screen sharing. A separate confirmation setting adds another step before a trade, with keyboard shortcuts for confirming or cancelling.

Who it is for

  • Users following event deadlines across time zones
  • Streamers and screen sharers who want portfolio values hidden
  • Traders who want an extra confirmation step for order clicks

    What to check

    • The provider says trade-confirmation dialogs are disabled on small screens; verify the behavior at your actual viewport size.
    • Portfolio masking covers displayed values, not every possible identifying element on a page.
    • Notifications depend on the browser and operating system’s permission and background behavior.
    • The countdown follows an event time; settlement can be a separate process.

    Our take on Polyteller

    Local-time reminders, portfolio masking and optional confirmations solve concrete browser-usage problems. Confirmation behavior varies on small screens and is not an exchange-wide restriction.
