ChatPlayground

ChatPlayground is a platform that sends a single prompt to several large language models at once and shows their responses side by side, so users can compare how ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, and other models answer the same question without switching between separate apps or subscriptions. Beyond plain comparison, the platform can also combine the individual answers from multiple models into one merged response. It is aimed at developers, researchers, writers, and business users who regularly need to check outputs across models, whether to pick the best answer for a task or to sanity-check one model against another. The interface also supports image generation, coding-related prompts, and uploading documents or images so a conversation can reference their content, extending it beyond text-only chat. A prompt library of ready-made templates and persistent chat history across sessions round out the workspace. Access is through a web browser rather than a native app, with a $20 a month subscription covering access to more than 30 supported models in one place instead of paying for each model's own subscription separately. Exact differences between pricing tiers, if any exist beyond the single plan mentioned, were not confirmed in the sources reviewed.
