Every AI Model in One App: GPT-5, Claude, Gemini and 50+

Yes, here is the app that has all of them

Yes, there is one app with all the major AI models. MultiChats gives you GPT-5, Claude Opus 4.6, Gemini 3.1, Grok, Mistral, and 50+ more behind a single subscription, and you can switch between them in the middle of a conversation without losing context. It runs on iOS, Android, and the web with one login and one bill.

Most people end up with a drawer full of AI tabs: ChatGPT in one window, Claude in another, Gemini somewhere else, and a separate tool for images. Each one wants its own monthly fee, and none of them talk to each other. The idea behind a single app is simpler. You pick the right model for each task in one place. Coding question? Reach for Claude or GPT-5. Quick research with sources? Switch to Gemini or turn on web search. Same thread, same history, no extra logins.

To be fair, if you only ever use one model and you like it, a single tool like ChatGPT on its own is perfectly fine. The case for one app gets strong the moment you find yourself comparing answers, paying two or three companies, or wishing you could move a conversation from one model to another.

Every model you get

MultiChats covers the major providers and stacks dozens of open models on top. Here is how the lineup breaks down by who makes them.

• OpenAI: GPT-5 and the lighter GPT-5 variants for fast everyday replies.

• Anthropic: Claude Opus 4.6 for heavier reasoning and writing, plus Claude Sonnet for quicker work.

• Google: Gemini 3.1 Pro and Flash, strong for research and long context.

• xAI: Grok, for a different voice and a different take on current topics.

• Mistral and open models: Mistral, Perplexity, and other open options for variety and cost-friendly tasks.

Five of these models are free to try, including GPT-5.4 Nano, Gemini 3.1 Flash Lite, and Mistral Small 3.2, with no credit card required. The free tier is genuinely usable for light, everyday questions, and it is a low-stakes way to feel out the model picker before you decide anything. If you want the deeper breakdown of who pays for what, our piece on one subscription for all AI models walks through it.

Switch models mid-conversation

This is the feature that changes how you work. The model picker sits on every message, so you can change models per reply and the conversation keeps its full history. Draft a first pass with GPT-5, tighten the wording with Claude, then verify a fact with Gemini, all inside one thread. Nothing gets copied and pasted between apps, and no context is lost when you hand off.

Once you get used to it, picking a model feels less like a commitment and more like choosing the right tool from a belt. A reasoning-heavy model for the hard part, a fast one for the cleanup. There is more detail in our guide to switching AI models mid-conversation, and if you mainly care about the two heavyweights, see chatting with GPT-5 and Claude in one place.

One thing worth calling out: the model you pick is the model you get. There are no silent model downgrades when traffic is busy, so a thread does not quietly get less capable halfway through.

One subscription vs paying separately

Buying each tool on its own adds up fast. Below is a rough picture of the comparable paid tiers from the major providers. Prices change often and vary by region, so treat these as ballpark figures, not a quote.

Stack those separate plans together and you are looking at $140 or more every month, before you add a dedicated image tool. One MultiChats plan covers the same models from $20.99 per month, or $199.99 per year, which works out to roughly $16.67 a month. We show the full math in our breakdown of what it costs to use all the AI models, and there is a wider list of options in how to stop paying for multiple AI subscriptions.

Beyond chat: image gen, voice, memory, and web search

Having every model in one app is the headline, but the surrounding features are what make it a daily driver. Here is what comes with a paid plan.

• Inline image generation. Create images on demand right inside the chat, without bouncing to a separate tool. Pro+ can generate several at once.

• Real-time web search and URL reading. Pull in current information, and paste any link to have the model read that page directly.

• Saved memories and folders. The app remembers context across chats, with per-folder customization so different projects stay separate. More on that in our look at AI chat with memory and folders.

• Voice messages and voice calls on mobile. Talk to the model hands-free when typing is a hassle. See our notes on the best AI voice mode.

• Private by default. There are no ads, and your conversations are not used to train models. We cover the policy in detail in no training on your data.

Note that memories, folders, web search, URL reading, per-chat notes on web, and voice are paid features. The free tier keeps things to basic chat with the five free models, which is the honest tradeoff for paying nothing.

Is this right for you?

If you live inside a single model and rarely compare answers, one provider's own app is probably enough, and there is no shame in that. The app makes the most sense when you already pay two or more AI companies, when you switch tools depending on the task, or when you are tired of model lock-in. If you are coming from a specific tool, you might find our ChatGPT alternative and Poe alternative pages useful for a direct comparison.

Frequently asked questions

Is there one app with all AI models?

Yes. MultiChats puts GPT-5, Claude, Gemini, Grok, Mistral, and 50+ more in one app on a single subscription, with five models free to try and no credit card required to start.

Can I use ChatGPT, Claude, and Gemini together?

Yes. All three are included, and you can switch between them inside a single conversation. That means you can draft with one, refine with another, and fact-check with a third, instead of paying for and juggling three separate apps. If you want to dig into how the top two stack up, see ChatGPT vs Claude vs Gemini.

How much does it cost?

Free to start with five models. Pro is $20.99 per month and gives you any model, image generation, web search, memories, folders, and more. Pro+ is $34.99 per month and adds multi-image generation, video uploads and analysis, conversation summaries, and the highest limits. Annual billing brings the per-month cost down further.

Will the model get quietly downgraded when servers are busy?

No. The model you select is the model that answers. Limits are transparent and predictable, so a conversation does not quietly drop to a weaker model in the middle of a task.

Does it work on mobile?

Yes. MultiChats runs on iOS, Android, and the web, and your chats, memories, and folders stay in sync across all of them. Voice messages and voice calls are available on mobile.

The bottom line

If you want every major AI model in one place, with mid-conversation switching and one bill instead of five, MultiChats is built for exactly that. Try it free with the five included models, and if it fits how you work, you can see the plans and pricing whenever you are ready. No pressure, and no credit card to start.
