TL;DR: A lifetime subscription to the ChatPlayground AI Unlimited Plan is $59.97 (reg. $619) through Oct. 25. Send one prompt to 20+ AI models, including ChatGPT, Claude, Gemini, and DeepSeek, and compare the answers.
DeepSeek, ChatGPT, and Gemini each win some comparisons and lose others. The only way to know which one fits a task is to try them all. ChatPlayground AI puts more than 20 models in one browser window, and until Oct. 25 at 11:59 p.m. PT, you can get a lifetime Unlimited Plan for $59.97 (reg. $619).
Write a prompt once, and ChatPlayground sends it to ChatGPT, Claude, Gemini, DeepSeek, Llama, Perplexity, and more simultaneously. Their answers show up next to each other. Finding the strongest one takes a quick read instead of copying and pasting between apps.
You can also upload a screenshot or PDF to see which model reads it best. Beyond that, you can generate AI images or use prompt-engineering tools to sharpen a request before you send it. Saved history lets you go back to earlier conversations.
ChatPlayground runs in Chrome, Edge, and Firefox on desktop, with no device limit. Messages are unlimited under a fair use policy, and Unlimited Plan members get priority access to new models and features. The models can’t search the web, and the lineup may change over time.
