I tested ten multi model AI chat platforms to save you the headache. Here is what I found.
1. AskAI.free
Quick stats: Free with paid upgrade. Best for all around use. Standout feature is its speed.
AskAI.free was the clear winner in my tests. It pulls from GPT 4, Claude, and Gemini all at once. You ask one question and it shows you answers from all three models side by side. This saved me a ton of time when I needed different viewpoints on the same topic.
The free plan is generous. You get lots of daily queries without hitting a paywall. The interface is clean and simple. No clutter. No ads. Just pick your models and get answers fast. It also remembers your chat history well.
Reasons to pick it:
- Free plan is actually usable
- See answers from multiple top models at once
- Very fast response times
2. Perplexity.ai
Quick stats: Free with Pro plan. Best for research. Standout feature is live web search.
Perplexity acts like a search engine and AI chat combined. It always pulls fresh data from the web. This makes it great for news, current events, or fact checking. The free version uses GPT 3.5, which is okay but not amazing.
The paid Pro plan gives you GPT 4 and Claude. That is where it shines. But for everyday casual chat, the free model feels slow and limited. It also struggles with longer conversations.
Reasons to pick it:
- Excellent for real time research
- Sources are shown clearly
- Free plan exists but is basic
3. OpenRouter.ai
Quick stats: Pay as you go. Best for power users. Standout feature is huge model selection.
OpenRouter is not a single chat app. It is a gateway to dozens of models. You pay per token for each call. This is great if you know exactly which model you want and need to control costs.
The downside is it is not beginner friendly. There is no simple chat interface. You need to use their API or a third party app. It also lacks a free plan. You must add money to your account first.
Reasons to pick it:
- Massive choice of models
- Pay only for what you use
- Good for developers and testers
4. Merlin.foyer.work
Quick stats: Free with paid upgrade. Best for productivity. Standout feature is browser extension.
Merlin lives inside your browser as an extension. It can summarize web pages, write emails, and answer questions based on what you are looking at. It uses GPT 4 and Claude on the paid plan.
The free plan gives you limited uses per day. It is enough for light tasks but not heavy work. The extension can sometimes slow down your browser. It also does not handle complex questions as well as standalone tools.
Reasons to pick it:
- Works right in your browser
- Great for quick summaries
- Free plan is decent for occasional use
5. Poe.com
Quick stats: Free with paid upgrade. Best for trying many models. Standout feature is a huge bot library.
Poe gives you access to GPT 4, Claude, Gemini, and many smaller models. You can chat with each one. The free plan gives you one message per day on the big models. That is frustrating.
You can also create your own custom bots. That is fun but takes time. The interface is clean and mobile friendly. But the free limit is too small for real testing. You will need to pay.
Reasons to pick it:
- Big selection of models
- Custom bot creation
- Free plan is very limited
6. Nat.dev
Quick stats: Pay as you go. Best for testing models. Standout feature is side by side comparisons.
Nat.dev lets you compare two models at once. You type a prompt and see both answers next to each other. This is useful for picking the best model for a task.
The downside is the interface feels clunky. It is not a polished chat app. It is more of a testing tool. You also need to add credit to use it. No free plan.
Reasons to pick it:
- Compare models directly
- Good for technical testing
- No free plan
7. HuggingFace.co
Quick stats: Free. Best for open source models. Standout feature is community models.
HuggingFace is a hub for open source AI models. You can chat with many of them for free. The models are often smaller and less powerful than GPT 4 or Claude.
The experience varies wildly. Some chatbots work great. Others are buggy or slow. It is not a polished product. It is more for people who want to experiment with new models.
Reasons to pick it:
- Completely free
- Access to cutting edge open source models
- Quality of models is inconsistent
8. Forefront.ai
Quick stats: Free with paid upgrade. Best for writing. Standout feature is persona based chats.
Forefront lets you pick a persona for the AI. It can act like a marketer, a teacher, or a friend. This is nice for specific tasks. It uses GPT 4 on the paid plan.
The free plan is limited to a few chats per day. The interface looks good but has bugs. Sometimes the persona feature feels gimmicky. It is not as reliable as other tools.
Reasons to pick it:
- Persona feature is creative
- Good for writing tasks
- Free plan is very limited
