Artificial Intelligence is evolving at breakneck speed, with new models, tools, and platforms being released almost every month. From large language models (LLMs) like GPT-4 and Claude to different proprietary versions like Mistral and Meta’s LLaMA family, staying up-to-date is challenging for developers, researchers, and curious users alike. Wouldn’t it be convenient if you could access and compare these models all in one place? Fortunately, a new breed of chat apps makes this possible.
TLDR:
Want to test and compare AI models without switching platforms? Several chat apps now offer side-by-side conversations with different AI models like ChatGPT, Claude, LLaMA, and more. The top apps include Poe, Chatbot Arena, and others designed to let users quickly experience how different models respond to the same query. This article highlights five of the most loved multi-model chat platforms you can access today.
1. Poe by Quora
Poe is a frontrunner when it comes to multi-model AI chat experiences. Developed by Quora, Poe serves as a one-stop solution for users to interact with several AI models from leading providers including OpenAI, Anthropic, Meta, and more.
- Models Available: GPT-4, Claude 3, LLaMA, and more
- Best For: Side-by-side chatbot testing and exploration
- Platforms: Web, iOS, Android
Poe shines with its clean interface and intuitive layout that allows quick toggling between models. Want to see how GPT-4 vs. Claude 3 handles a creative writing prompt or a tricky ethical question? Poe lets you do just that—instantly.

2. Chatbot Arena (LMsys Chat)
Chatbot Arena, hosted by LMsys, offers a brilliantly simple but powerful platform: you type a prompt and get two anonymous outputs from different AI models. You don’t know which model is which—until after you vote on which one you prefer. This blind comparison introduces an element of objectivity and discovery.
- Models Available: GPT-4, Claude, LLaMA, Mistral, and others
- Best For: Blind testing of model responses
- Platforms: Web browser
Originally developed for academic benchmarking, Chatbot Arena now appeals to anyone curious about how different AI models “think.” The response pairings change often, so you can test again and again to get varied results. It’s one of the most fair and unbiased ways to compare models head-to-head.
3. HuggingChat
HuggingChat is the official online chat interface from Hugging Face, a company renowned for making open-source AI models more accessible. HuggingChat allows you to test several LLMs directly in your browser—including open-source models you might not find elsewhere.
- Models Available: LLaMA, Zephyr, Mistral, Falcon, and other open-source LLMs
- Best For: Free use of open-source models
- Platforms: Web
While most platforms integrate mainly closed-source models like GPT-4, HuggingChat’s strength lies in promoting AI transparency. You’re not just using the models—you can explore their datasheets, licensing terms, and GitHub repos right from the chat interface.
The versatility of HuggingChat lies in its developer-friendly ethos. You can even clone bots, incorporate models into your apps, and build fully community-powered AI experiences.
4. OpenRouter Playground
OpenRouter is less of a consumer-facing app and more of a gateway to advanced AI testing for power users. However, its built-in playground interface is simple enough for casual users while offering developer-grade flexibility underneath.
- Models Available: More than 30, including Claude 3, GPT-4, Mixtral, LLaMA, Mistral, and custom APIs
- Best For: Developers and researchers doing in-depth analysis of prompt responses
- Platforms: Web only
The playground section allows side-by-side prompts for multiple models, showing token usage, response time, and even nuanced differences in output behavior. OpenRouter is also unique for letting users route API calls through a single interface regardless of model provider—OpenAI, Azure, Anthropic, and more.
If you’re serious about tailoring responses or optimizing LLM performance, OpenRouter offers the most granular control out there.
5. Chatverse
Chatverse is the newest entrant in the multi-model chat space—and it’s been making waves. This platform emphasizes personalization and community, offering not just access to different models, but also user-created bots and shared prompt libraries.
- Models Available: GPT-4, Claude, and other models integrated via APIs
- Best For: Community-driven prompt sharing and customization
- Platforms: Web and mobile app
Users can rate model responses, follow popular bots, and create topics for discussion. This transforms what is usually a singular AI experience into a vibrant community of AI-powered conversations. Also great for educators sharing lesson plans or companies building customer support tools.

As the number of AI models continues to grow, the value of easy comparison platforms becomes immense. Whether you’re an AI researcher curious about LLaMA-3’s newest capabilities, or just someone comparing GPT-4 with Claude for a school essay, these platforms save time and promote informed decisions.
Additionally, these apps foster transparency, experimentation, and fairness in evaluation. They pierce through fan hype or marketing promises by letting you judge for yourself. In some cases—like with Chatbot Arena—you even help the AI research community by submitting your votes or feedback to improve datasets.
What to Consider When Choosing a Multi-Model Chat App:
- Pricing: Some platforms offer limited usage for free, while others charge subscription or pay-per-request fees.
- Model Diversity: Look for platforms featuring both open-source and closed-source models.
- User Interface: Smooth UX/UI can significantly enhance your model evaluation experience.
- Customization: Ability to modify prompts or build custom bots is a plus.
- Community Engagement: Features like collaborative testing, ratings, and feedback options can add value.
Final Thoughts
Gone are the days of needing multiple accounts or developer keys just to see how different AI models respond to a simple prompt. Thanks to innovative apps like Poe, Chatbot Arena, HuggingChat, OpenRouter, and Chatverse, comparing multiple AI models is now easier—and more fun—than ever.
If you’re actively using AI for tasks ranging from coding assistance and content creation to philosophical debates and linguistic experiments, these platforms deserve a bookmark. Load them up, test your prompt across 5 or 6 models, and see which intelligence wins your trust.
Welcome to the golden age of AI discovery—smart, diverse, and just a click away.
