A popular new platform gives you lifetime access to GPT, Claude, Gemini, and more for $60

TL;DR: ChatPlayground gives you access to 20+ AI models like GPT and Claude and lets you compare outputs, and it’s only $60 for life.

Most AI models are only really good at a few things. The problem is that you end up wasting a ton of time comparing results when you’re running multiple models, and that doesn’t even get into the cost of maintaining multiple AI subscriptions.

ChatPlayground is a new platform that fixes both of those problems by giving you lifetime access to popular models like GPT and Claude and giving you a simple workspace that lets you send one prompt to multiple models. It’s also on sale for only $59.97 (reg. $619) through July 19.

ChatPlayground AI sends any prompt to several models at once and lines up the responses in one window, so you can see how they differ and pick what works best. The platform supports more than 25 models, including ChatGPT, Gemini, Claude, Deepseek, Llama, and Perplexity, among others. That means you can use the same workflow for chat, coding help, content drafts, or image ideas and compare model output without copying and pasting everywhere.

You can tweak a prompt, run it again, and see how each model changes the answer. Prompt engineering tools help you refine and reuse prompts that work well. ChatPlayground AI also lets you upload images and PDFs, then ask questions about them, so you can check how different models handle the same document or screenshot. Saved chat history keeps longer projects and useful prompts easy to revisit.

The Unlimited Plan is a lifetime subscription with unlimited messages each month. It’s aimed at prompt engineers, startups, and teams that test or use AI heavily and need room to experiment. You can use it on any desktop that runs a recent version of Chrome, Edge, or Firefox, with no set limit on how many devices you sign in from.

There’s a smarter way to use AI. Until July 19 at 11:59 p.m. PT, get a ChatPlayground AI lifetime subscription on sale for $59.97.
