ChatHub is a browser extension that lets you talk to multiple AI models at the same time. You type one prompt and see how GPT-5, Claude, Gemini, and others respond side by side. It's useful for comparing model quality on specific tasks and figuring out which AI gives the best answer for your use case.
But ChatHub isn't the only option. The multi-AI chat space has grown a lot since 2024, and some alternatives offer better features, more models, or lower prices. Here's an honest comparison of what's out there.
ChatHub Alternatives Compared

|---|---|---|---|---|---|
| ChatHub | Browser extension | GPT, Claude, Gemini, more | Limited | $6.99/mo | Side-by-side comparison |
| Poe | Web + mobile app | GPT, Claude, Gemini, Llama, custom bots | Yes | $19.99/mo | Variety of models + community bots |
| Merlio | Web app | GPT, Claude, Gemini, Mistral, more | Yes | Varies | All-in-one AI tools (chat + image + video) |
| Octofy | Web app | GPT, Claude, Gemini, DeepSeek | Limited | ~$10/mo | Smart model auto-selection |

| Perplexity | Web + mobile | Proprietary + GPT, Claude | Yes | $20/mo Pro | Web research with AI |
Why People Look for ChatHub Alternatives
ChatHub works well for what it does, but there are some common complaints that push people to look elsewhere:
- It's a browser extension, not a standalone app. You depend on Chrome, and the extension can break after browser updates
- The free tier is very limited. You hit the paywall fast
- No mobile version. If you're not at a desktop, you can't use it
- Side-by-side comparison is great for testing but awkward for actual work. Most people don't need to see 4 responses to every message
If your main use case is comparing models for research or evaluation, ChatHub is still one of the best at that specific thing. But if you want a daily-driver AI chat that happens to support multiple models, there are better options.
Poe: Best for Model Variety
Poe (by Quora) is probably the closest full-featured alternative. It gives you access to GPT-5, Claude, Gemini, Llama, and a huge library of community-created bots, all from one interface. The mobile app is polished and the web version works well.
The free tier is usable but limited. The $19.99/month Pro plan removes limits and gives priority access to all models. What makes Poe unique is the custom bot ecosystem. Users have built thousands of specialized bots for specific tasks, and you can create your own using any supported model as a base. It's more of a platform than just a chat tool.
Merlio: Best All-in-One (Chat + Image + Video)
Merlio takes a different approach. Instead of just chat, it bundles text generation, image generation, video generation, and more into one platform. You can switch between AI models for chat (GPT, Claude, Mistral, and others), then hop over to text-to-image or text-to-video tools without leaving the site.
If you only need multi-model chat, Poe might be a better fit. But if you regularly use AI for both conversation and content creation, having everything in one place saves you from juggling multiple subscriptions. The free tier covers basic usage across all tool types.
TypingMind: Best for Power Users with API Keys
TypingMind is for people who already have their own API keys from OpenAI, Anthropic, or other providers. You pay $39 once (no subscription), bring your own keys, and get a polished chat interface with features like conversation folders, prompt templates, and plugins.
The appeal is control and cost. If you're already paying for API access, TypingMind adds zero monthly cost while giving you a much better interface than the default API playground. The downside is that you need to manage your own API keys and costs. Not ideal for non-technical users.
HuggingChat: Best Free Option
HuggingChat is completely free and runs on open-source models hosted by Hugging Face. You get access to models like Llama, Mistral, and others without any signup or payment. The quality varies by model, and it doesn't have GPT or Claude, but for a free option with no catches it's hard to complain.
It's best for people who want to try different open-source models without setting up anything locally. If you're evaluating whether to run a local model, HuggingChat lets you test the quality first in a browser.
Which One Should You Pick?
- Need side-by-side comparison specifically: stick with ChatHub
- Want the most models + community bots: Poe ($19.99/mo)
- Want chat + image + video in one place: Merlio
- Have your own API keys: TypingMind ($39 one-time)
- Want completely free, open-source: HuggingChat
- Primary use is research: Perplexity ($20/mo Pro)
Most people who leave ChatHub end up on either Poe (for the model variety) or a platform like Merlio (for the broader tool set). The right choice depends on whether you're looking for just chat or a broader AI toolkit.
