Overview
When comparing PolymarketOddsConverter (extension) vs Polyprophet, it becomes clear that these two browser extensions serve meaningfully different purposes within the Polymarket ecosystem. PolymarketOddsConverter is an open-source project available for Chrome and Firefox that focuses on a single, well-defined task: converting Polymarket's implied probabilities into decimal odds, giving bettors a familiar format for evaluating markets. Polyprophet, on the other hand, is a Chrome-only extension that promises AI-powered real-time predictions by leveraging multiple AI models and proprietary historical data analysis. Both tools are currently listed as coming soon, meaning neither has reached a publicly confirmed stable release at the time of writing.
Despite sharing the same browser-extension delivery format, the two tools occupy opposite ends of the utility spectrum. PolymarketOddsConverter is a lightweight, transparent utility built for odds-format convenience, with its codebase publicly available on GitHub. Polyprophet positions itself as a more ambitious, data-driven assistant aimed at users who want automated predictive guidance rather than simple number conversion. Understanding what each tool actually promises — and what remains unverified — is essential before deciding which, if either, fits your workflow.

| Feature | PolymarketOddsConverter (extension) | Polyprophet |
|---|---|---|
| Primary Function | Converts implied probabilities to decimal odds | Provides AI-generated real-time market predictions |
| Target User | Traders familiar with decimal/fractional odds formats | Traders seeking AI-assisted predictive insights |
| Platform / Browser | Chrome and Firefox | Chrome only |
| Automation Level | Low — passive display conversion | High — active AI model inference and recommendations |
| Pricing | Free and open source (MIT/GitHub) | Not publicly disclosed; proprietary product |
| Key Strength | Transparency, simplicity, open-source auditability | Multi-model AI analysis and historical data integration |
| Best For | Quick odds-format reference without data overhead | Users wanting automated predictive decision support |
When to Choose PolymarketOddsConverter (extension)
PolymarketOddsConverter is the right pick if you simply want Polymarket's probability displays rendered in a decimal odds format you already understand — no more, no less. Because it is open source and hosted on GitHub, technically inclined users can audit exactly what the extension does before installing it, which is a meaningful trust advantage. It is a no-frills, privacy-respecting utility that does one thing well.
- You are a sports bettor or traditional odds trader who thinks natively in decimal or fractional formats rather than implied probability percentages.
- You prefer open-source software you can inspect, fork, or contribute to rather than relying on a closed proprietary product.
- You use Firefox as your primary browser and need cross-browser compatibility that Polyprophet does not currently offer.
When to Choose Polyprophet
Polyprophet is aimed at users who want more than a display converter — specifically, those who want AI-generated predictive signals layered directly onto their Polymarket browsing experience. If the core value you seek is automated analysis drawing on multiple AI models and historical market data, Polyprophet's stated feature set is far more relevant. Keep in mind that because it is still listed as coming soon and pricing is undisclosed, committing to it requires more trust than an open-source alternative demands.
- You want real-time AI-driven probability assessments to complement or challenge Polymarket's crowd-implied odds.
- You are comfortable using a proprietary Chrome extension and are willing to evaluate a paid or freemium pricing model once it launches.
- You prefer an all-in-one analytical layer rather than managing separate research tools alongside a basic odds converter.
Verdict
Both tools are coming soon, so neither can be fully recommended based on confirmed live performance. That said, PolymarketOddsConverter offers a clear, verifiable, and free value proposition — odds conversion — with the accountability of open-source code. Polyprophet promises a more powerful feature set with AI-backed predictions, but its closed nature, undisclosed pricing, and pre-release status introduce meaningful uncertainty. If you need a reliable utility today, PolymarketOddsConverter is the safer starting point. If AI-assisted prediction assistance is your priority and you are willing to wait and potentially pay, Polyprophet warrants watching — but reserve judgment until it launches and independent users can verify its claims.
