What It Is

Polyteller is a Chrome extension for Polymarket traders. It is not positioned as a full trading platform, but rather as a browser-based companion tool. It focuses on solving several practical issues in prediction market trading: misreading event end times, missing reminders near deadlines, exposing position values in public settings, and accidentally clicking trading buttons.

Core Features and Integrations

Its core modules include a real-time countdown in the local time zone, custom notifications, one-click privacy mode, and trade safety confirmations. The countdown automatically converts event times to the local time zone, handles daylight saving time changes, updates in real time, and syncs with Polymarket servers for better accuracy. Notifications support multiple reminder points for a single event, such as 1 hour, 30 minutes, or 5 minutes before closing. Privacy mode can mask portfolio values and balances across all Polymarket tabs, making it useful for screen sharing or use in public places. The trade safety feature reduces the chance of misclicks through optional confirmation pop-ups, Enter/Esc shortcuts, and a cancellation countdown.

Pricing and Deployment

The page clearly states “Add to Chrome - It's Free,” so it can currently be considered free to use. However, it does not disclose whether there is a premium version, paid plan, or future business model. Deployment is via a Chrome browser extension, supporting Chrome as well as Chromium-based browsers such as Edge and Brave 110+. There is no sign of self-hosting, an API, developer documentation, or enterprise management features.

Pros and Cons

Its strengths are that the product is highly focused on high-frequency Polymarket use cases, easy to install, simple to use, and free. For active traders, time zone conversion, reminders, and trade confirmations all provide practical value. The drawbacks are also clear: it is not a general-purpose SaaS product, and it lacks team collaboration, permission controls, data security and compliance explanations, and open integrations. Although the page emphasizes “Privacy First,” it does not explain data collection practices, browser permissions, or compliance certifications.

Who It’s For and Access from China

Polyteller is best suited for individual Polymarket traders, especially users who care about event closing times, frequently browse markets across multiple tabs, or need to hide asset information in public environments. Access from China cannot be determined from the page alone. It also depends on the Chrome Web Store and the Polymarket usage environment, so real-world availability may be affected by network conditions and access to related services. If it cannot be used, alternatives include Polymarket’s native reminders, calendar/browser reminder tools, or similar extensions.
