TL;DR: ChatPlayground lets you send one prompt to multiple AI models, and lifetime access is now only $69.97 with code May5.

Anyone who has worked with AI tools knows that different models can give wildly different answers to the same prompt. Manually sending each prompt to each model to find the best option wastes a ton of time, which is why tools like ChatPlayground AI are growing in popularity. ChatPlayground lets you run multiple AI models at the same time, and a lifetime subscription just went on sale for $69.97 (reg. $619).

ChatPlayground has a simple premise that ends up saving a ton of time and frustration. Instead of manually working with a bunch of different AI models, ChatPlayground lets you talk to them all together. The platform supports more than 20 AI models, including ChatGPT, Gemini, Claude, Deepseek, Llama, and Perplexity, among others. That means you can use the same workflow for writing, coding help, generating ideas, or creating images, and then compare the output.

Don’t like any of the results a prompt gave you? You can tweak it and run it again to see how each model changes their answer. There are even prompt engineering tools to help you refine and reuse the prompts that worked well. ChatPlayground even lets you upload images and PDFs, then ask questions about them, so you can actually check how different models work with the same document.

The Unlimited Plan does exactly what it says. It lasts for life with no recurring payments, and you get unlimited messages every month. It’s also on sale through May 17 for only $69.97 with code May5.
