What is PolyGPT ?
PolyGPT is a powerful, free, and open-source desktop application designed for AI power users, developers, and researchers who require reliable, efficient comparative analysis of large language model outputs. It fundamentally solves the frustration of constant tab-switching, providing a unified, cross-platform interface where you can prompt leading services like ChatGPT, Gemini, Claude, and Perplexity simultaneously, enabling instant, side-by-side comparison of their results.
Key Features
PolyGPT delivers a streamlined workflow built for speed and informed decision-making:
⚡ Unified Input and Simultaneous Querying
Type your prompt just once, and PolyGPT instantly mirrors that input across all active AI model interfaces. This capability ensures maximum efficiency, allowing you to launch queries to multiple providers—including ChatGPT, Gemini, and Claude—at the exact same moment, drastically cutting down on research and development time.
📊 4-Way Split View for Instant Analysis
Visualize responses in a flexible 2x2 grid, placing up to four different models (e.g., ChatGPT, Claude, Gemini, and Perplexity) directly side-by-side. This immediate visual comparison is invaluable for assessing response quality, style, and accuracy, enabling you to select the optimal output without manual copy-pasting or interface juggling.
🔒 Data Privacy and Zero-Friction Access
PolyGPT is 100% private and collects zero user data. Crucially, it uses the official web interfaces directly, meaning your login credentials remain strictly between you and your chosen AI provider. You don't need to manage or expose sensitive API keys, simplifying setup while maintaining a high standard of security.
🖥️ Supersize Mode for Focused Work
When a specific model's response requires deep focus or detailed review (such as debugging a large block of code or analyzing complex data), you can instantly expand any single quadrant up to 80% width. This allows you to maintain context while dedicating maximum screen space to the relevant task, then quickly revert to the full comparison view.
PolyGPT stands apart by focusing on user control, privacy, and accessibility, making it the definitive tool for cross-model AI interaction.
- Truly Open Source and Free: PolyGPT is completely free and open source, ensuring transparency in its operations and allowing the community to verify its privacy claims. There are no hidden costs or premium tiers for core functionality.
- Desktop Native Performance: Delivered as a cross-platform application (macOS, Windows, Linux), PolyGPT offers superior stability, session persistence, and dedicated zoom controls, providing a smoother, more reliable experience than relying on browser tabs.
- Direct Web Interface Utilization: Unlike many aggregators that require managing and paying for individual API keys, PolyGPT uses the official public web interfaces. This means you can leverage your existing free or subscription-based access directly, without the added complexity or cost of managing complex API billing.
Conclusion
PolyGPT delivers the efficiency and insight required to leverage the full potential of today's leading AI models. By eliminating friction and enabling instant comparison, it transforms the way you interact with generative AI. Stop switching tabs and start comparing results instantly.
