10 Best Websites to Use Multiple AI Tools in One Place

Here is the maths that pushes most people toward these platforms. ChatGPT Plus is $20 a month. Claude Pro is another $20. Gemini Advanced makes $60. Add Perplexity and you are at $80 before touching image generation.

Worse than the cost is the friction. You copy a prompt into one tab, wait, paste it into another to compare tone, then jump to a third to check a fact. One user summed it up well: they use each tool about 30% of the time but pay for 100% of each.

Platforms that put all AI tools in one website solve both problems. Here are ten worth knowing, and the trade-offs nobody mentions in the marketing.

Why Use Multiple Chat AI at Once?

Running one prompt through several models is not just about saving money. It changes the quality of what you get.

• Cross-checking answers. If two models contradict each other, you know the claim needs verification before you act on it.
• Matching model to task. One model may write better copy while another reasons more carefully through code or data.
• Avoiding lock-in. Model leadership changes every few months. A multi-model workspace means you are never stuck with last quarter’s best.
• One prompt, several drafts. Send one instruction and compare tone, structure, and confidence side by side.

Three Types of Platform

Before comparing tools, understand which category you need. They solve different problems.

Bundled subscription platforms charge one flat fee and include model access. Simplest option, but you are trusting their infrastructure and usage caps.

Bring-your-own-key tools give you an interface and connect to your own API keys. You pay providers directly at list rates with no markup, and your prompts go straight to the model provider.

Developer API gateways give one endpoint for hundreds of models. Built for people shipping products, not chatting.

10 Best Websites With All AI Tools in One Place

1. Poe

The most polished entry point for general users. Poe gives access to GPT, Claude, Gemini, Llama, and a large ecosystem of custom bots, with mobile apps alongside the web version. There is a free tier, though premium models sit behind a subscription around $20 a month. Best for casual users and content creators who want zero setup.

2. OpenRouter

The infrastructure layer of this category. One API key reaches 300 or more models across dozens of providers, with automatic routing, fallbacks, and load balancing. Pricing is pay-per-token with a small fee on credit purchases. Best for developers building applications, and overkill if you just want a chat window.

3. ChatHub

Purpose-built for using multiple chat AI at once. ChatHub runs 20 or more chatbots simultaneously, available as both a web app and a browser extension. Image generation is included. Free to start, with a premium plan for heavier usage. Best for people whose main goal is genuine side-by-side comparison.

4. ChatAll

The strongest free option. ChatAll is open source, requires no signup, and displays ChatGPT, Claude, Gemini, DeepSeek, and Llama responses side by side. Because the desktop client’s code is published, security-conscious users and teams can inspect what runs on their machine. Best for anyone who wants comparison without a subscription.

5. TypingMind

TypingMind takes the opposite approach to bundled platforms. It never holds your API keys or your data. You bring keys from OpenAI, Anthropic, and Google, and it acts as a polished frontend. Available as a one-time purchase around $59 or by subscription. Best when data privacy is non-negotiable and you dislike recurring fees.

6. Perplexity

Technically a research tool, but Pro subscribers can switch between frontier models while keeping live web access and citations on every response. That combination is hard to replicate elsewhere. Around $20 a month. Best when your work depends on current information rather than training data.

7. ChatPlayground

Built around parallel comparison. One input goes to every selected model simultaneously, making comparison a normal step rather than extra work. Priced around $20 a month, roughly what a single premium plan costs. Best for writers and analysts who compare outputs constantly.

8. MultipleChat

Goes beyond comparison into collaboration. Models can review each other’s work, and the platform adds prompt optimization, output verification, web research, and document workspaces. Plans start near $20 a month with a limited free tier. Best for people who want models cross-checking each other automatically.

9. Magai

Built for marketers rather than generalists. Alongside multi-model access, it focuses on brand voice consistency, saved prompt libraries, and team collaboration around AI-generated content. Best for content teams where staying on-brand matters more than raw model breadth.

10. Merlin

A browser extension rather than a destination site. Merlin sits on top of pages you are already reading, letting you query multiple models without switching context. Paid, and desktop browser only. Best for research-heavy work where the AI should come to the page rather than the reverse.

Comparison Table

Pricing in this category changes frequently. Confirm on the vendor’s page before subscribing.

What You Give Up

This is the section most articles skip, and it matters more than the feature lists.

• Free tiers often serve older models. Several platforms reserve current frontier models for paid plans, giving free users distilled or previous-generation versions. That defeats the purpose of comparing frontier models.
• New releases arrive late. When a lab ships a new model, aggregators need time to integrate it. Going direct is always fastest.
• Native features do not carry over. Things like project workspaces, artifacts, code execution, and connectors exist in the official apps. Third-party interfaces usually offer a plain chat window instead.
• Usage caps replace unlimited plans. Bundled platforms manage cost through message limits. Heavy users can hit them faster than expected.
• Your data takes a detour. Unless you use a bring-your-own-key tool, prompts pass through a third party. Read the data policy before sending anything sensitive.
• Cost can invert. For heavy users paying per token, an aggregator can end up more expensive than a flat subscription.

How to Choose

Match the platform to how you actually work.

• You want the simplest switch from one subscription: Poe.
• You want to compare answers constantly: ChatHub or ChatPlayground.
• You want it free: ChatAll.
• Privacy is the priority: TypingMind with your own keys.
• You need current, cited information: Perplexity.
• You are building software: OpenRouter.
• You run a content team: Magai.

A practical test: run the same real task through two candidates for a week. Whichever one you stop resenting is the right choice.

Should You Cancel Your Direct Subscriptions?

Not immediately. A reasonable approach is to keep one direct subscription for the model you rely on most, and use a multi-model platform for everything else. That gives you native features and day-one access where it matters, plus breadth and cheaper experimentation elsewhere.

If your usage is genuinely spread across three or more models, consolidating fully makes sense. If 80% of your work happens in one model, the savings are smaller than the marketing suggests.

Final Thoughts

The case for putting all AI tools in one website is strongest for people who compare, experiment, or switch models often. It is weakest for people with one deep workflow in a single tool.

Start with a free option like ChatAll or ChatHub before paying anything. A week of real use will tell you whether multi-model working suits you far better than any comparison table, including this one.
