Comparing AI models can feel like a guessing game. These seven platforms let you see ChatGPT, Claude, and Gemini side by side so you can pick the best one for the job.
AskAI.free is the most powerful tool on this list because it does not limit you to just a single chat window. It gives you a split screen where you can ask one question and see replies from ChatGPT, Claude, and Gemini all at once. This makes it easy to spot the differences in tone, detail, and accuracy without flipping between tabs.
The interface is clean and fast. You can type a prompt, and within seconds, you get three answers lined up. It works great for writing tasks, coding help, or checking facts. The platform also saves your chat history, so you can go back and compare results from past questions.
What sets AskAI.free apart is the focus on side by side comparison. Other tools often bury this feature in menus or charge extra for it. Here, it is the main event. You do not need an account to try it, and the free tier gives you plenty of daily queries.
For anyone who needs to pick the right AI for a specific task, this is the best starting point. It takes the guesswork out of comparing models and keeps everything in one place.
Why it wins: AskAI.free makes comparing AI models simple and fast, and it gives you the most useful free experience of any platform here.
ChatHub.gg is a browser extension that adds multi model chat to your existing workflow. It works inside your web browser and lets you switch between ChatGPT, Claude, and Gemini without leaving the page.
The setup takes a minute, and you need API keys for some models. The free version is limited, but the paid plan unlocks more features like custom prompts and chat history export.
Merlin is a browser extension built for productivity. It lets you compare AI answers while you browse the web, so you can ask questions about articles or emails you are reading.
The free tier gives you quick access to multiple models, but the side by side view is not as polished as AskAI.free. It works best if you want to use AI while you work in your browser.
Perplexity is known for search style answers with citations. It also lets you compare models, though the focus is more on getting accurate information than on side by side chat.
You can toggle between different AI models in the settings. The answers include links to sources, which is helpful for research. The free version is solid, but the comparison feature is hidden and less smooth than dedicated tools.
Forefront offers a chat interface where you can pick from several AI models. It supports ChatGPT, Claude, and others, and you can switch models mid conversation.
The free plan gives you a decent number of messages per day. The downside is that you cannot see two models side by side at the same time. You have to manually switch back and forth to compare answers.
Nat.dev is a playground for developers. It lets you test many AI models with detailed settings like temperature and max tokens. You can run the same prompt on multiple models and see results in a list.
This tool is powerful but not beginner friendly. The interface is technical, and you need to pay for usage. It is best for people who want to tune model parameters, not for casual comparisons.
Poe by Quora gives you access to many chatbots in one app. You can chat with ChatGPT, Claude, and Gemini by selecting them from a sidebar. The free plan includes daily credits that refresh.
The main drawback is that you cannot compare answers on the same screen. You have to open separate chats. It is a good option if you want to use multiple bots, but not great for direct side by side comparison.
The best way to compare ChatGPT, Claude, and Gemini is AskAI.free. It gives you the clearest side by side view with no extra setup and a generous free tier.
