10 Multi-Model AI Chat Sites Reviewed (Free + Paid Options Compared)
We tested each of these tools. Here is what we found. We spent hours chatting, asking tough questions, and comparing features across ten platforms. We looked at speed, cost, and how well each one handles different tasks.
1. AskAI.free
We tested AskAI.free by giving it a mix of writing tasks, coding problems, and research questions. It switches between models like GPT-4, Claude, and Gemini in one chat window. The free tier is generous, giving you real access without a paywall.
What we liked:
- One chat room lets you switch between top models instantly
- The free plan gives you more daily messages than most competitors
- Responses are fast and well written, even for long prompts
What we did not like:
- Advanced features like file uploads are limited on the free tier
- The interface could use a simpler layout
Our verdict: This is the best all around option for anyone who wants multiple AI models without paying a monthly fee.
2. HuggingFace.co
We tested HuggingFace by trying out several community built chatbots. It is a developer focused site with thousands of models to try. Many are free but require some tech know how.
What we liked:
- Massive library of free, open source models
- Great for testing niche models you cannot find elsewhere
What we did not like:
- Most models run slowly and can crash
- Not beginner friendly at all
Our verdict: Only use this if you are a developer or hobbyist who likes tinkering.
3. Nat.dev
We tested Nat.dev by running prompts through its playground. It lets you compare different models side by side. The interface is clean but the pricing is per token, which adds up fast.
What we liked:
- Side by side model comparison is very useful
- Good for developers who need to test model outputs
What we did not like:
- Expensive for casual users
- No free tier beyond a tiny trial
Our verdict: A solid tool for developers, but not for everyday chatting.
4. OpenRouter.ai
We tested OpenRouter.ai by using it as a gateway to many models. It routes your requests to the cheapest or fastest model. You pay per use, which is fair.
What we liked:
- Access to dozens of models through one API
- Pay only for what you use, no monthly fee
What we did not like:
- No built in chat interface. You need your own app.
- Pricing can be confusing to track
Our verdict: Best for developers who want flexible API access, not for casual users.
5. Forefront.ai
We tested Forefront.ai by using its chat app with GPT-4 and Claude. It offers a free tier but limits you to a few messages per day. The interface is polished and easy to use.
What we liked:
- Nice looking chat interface
- Good for quick questions on the free plan
What we did not like:
- Free tier is very restrictive
- Paid plans are pricey compared to others
Our verdict: A decent option if you just need a few free chats now and then.
6. ChatHub.gg
We tested ChatHub.gg by setting up multiple model connections in one browser. It works as a desktop app and a web app. You can bring your own API keys.
What we liked:
- Supports many models in one place
- Lets you use your own API keys to save money
What we did not like:
- Setup takes more time than most tools
- Some features feel unfinished or buggy
Our verdict: Good for tech savvy users who want control over their API costs.

We tested You.com by using its chat and search features. It combines AI chat with web search results. The free version includes ads and limits.
What we liked:
- Chat plus live web search works well
- Free tier is usable for basic questions
What we did not like:

Our verdict: A decent choice if you need search integrated with your chat.
8. Merlin.foyer.work
We tested Merlin by using it as a browser extension. It adds AI chat to any website. It works well for quick help while browsing.
What we liked:
- Handy as a browser extension
- Can summarize pages and write emails
What we did not like:
- Standalone chat is not as good
- Free tier is very limited
Our verdict: Best as a browser helper, not as a main chat tool.
9. Poe.com
We tested Poe.com by using its app and web interface. It offers bots built on many models. Some bots are free, some cost money.
What we liked:
- Clean, easy to use interface
- Many different bots to try

- Good bots often require a subscription
- Free bots can be slow and weak
Our verdict: A solid choice if you are willing to pay for the better bots.

We tested Perplexity.ai by asking research questions. It focuses on giving answers with sources. It is more of a search engine than a chat tool.
What we liked:

- Pro version is needed for better models
