If you’ve been comparing GPT-5 to Claude 4.7 to Gemini 2.5 to Mistral Large by the actual quality of the answer, you’ve probably also been paying for four separate subscriptions. The trick that the OpenRouter community figured out a couple of years ago is that you don’t have to. Aggregator apps and routers let you keep one account, one bill, and one chat history while you swap between the model that’s best for the question.
We tested seven apps that let you talk to multiple AI models from a single Android interface. The shortlist below covers free-tier setups, pay-as-you-go credit pools, and aggregator browsers that route everything through one app.
What to look for in a multi-LLM app
- Which models it actually carries. A “200+ models” claim is meaningless if the eight you care about are missing. Confirm GPT-5, Claude 4.7, Gemini 2.5, Mistral Large, and Llama 3.3 before you pay.
- How it charges. Subscription tiers feel cheap until you blow through the cap. Pay-per-token gives you control but you need to watch the meter.
- Conversation portability. Aggregators that lock chats inside their own format make it painful to move later. Export to plain text or JSON matters.
- Image, audio, and file input. Half the multimodal value of GPT-5 and Gemini 2.5 disappears if the app can only send text.
- Privacy stance. Some aggregators forward your prompts to providers verbatim. Others strip metadata. If you’re sending work content, that matters.
- API key bring-your-own. Apps that accept your own provider keys let you keep usage on your existing OpenAI or Anthropic account instead of paying twice.

The apps
1. Perplexity — Best for search-style queries
Perplexity is the easiest landing pad for anyone who’d rather ask a question than craft a prompt. The Pro plan lets you switch the model behind each answer between GPT-5, Claude 4.7 Sonnet, Gemini 2.5, and Perplexity’s own Sonar. Every reply ships with citations, the file-upload accepts PDFs and images, and Spaces give you per-project conversation history that doesn’t bleed between work and personal.
Where it falls short: The free tier limits Pro Search to a handful of queries a day. The default model picker is hidden two taps deep in the answer.
Pricing: Free for unlimited basic queries. Pro costs around a typical streaming subscription per month.
Platforms: Android, iOS, web, macOS, Windows.
Bottom line: Start with Perplexity if you want a single subscription and you ask questions more than you write code.
2. Poe — Best for threaded chats
Poe (by Quora) is the aggregator with the broadest current model lineup in a consumer app. The Pro tier opens up GPT-5, Claude 4.7 Sonnet and Opus, Gemini 2.5, Llama 3.3, and Mistral Large under a single message-credit budget. Custom bots let you save a system prompt plus a model pairing and reuse it the way you’d save a Slack shortcut.
Where it falls short: Poe isn’t published on Google Play in every region. You may need to sideload the APK from the Quora developer page. Message credits also feel restrictive once you start using Opus heavily.
Pricing: Free with a daily message cap. Pro starts in the mid-teens per month.
Platforms: Android, iOS, web, macOS, Windows.
Bottom line: Poe is the closest thing to a single chat client for every major model.
3. OpenRouter — Best for API-key power users
OpenRouter isn’t a chat app, it’s a unified billing layer that fronts hundreds of models behind one API key. On Android you use it through one of the third-party clients (ChatBox, MyMind, Chatterbox, or any LibreChat install). You top up credit, pick a model per message, and the router handles routing, billing, and fallbacks if a provider is down.
Where it falls short: No first-party Android app yet. Setup involves an API key and a third-party front end.
Pricing: Pay-as-you-go. You pay only for the tokens you spend, plus a small router fee.
Platforms: Web. Android via third-party clients.
Bottom line: OpenRouter is the cheapest path once you understand tokens. Skip it if you’re new to AI tools.
4. ChatHub — Best for side-by-side comparisons
ChatHub is the multi-pane app. You can ask the same question to GPT-5 and Claude 4.7 in two columns and watch them stream in parallel. The mobile layout swipes between panes rather than stacking them, which works better than the desktop UI suggests. Custom bots and prompt libraries carry across devices.
Where it falls short: The free tier limits side-by-side mode to two models. The chat history can be slow to load over a flaky connection.
Pricing: Free with limits. Premium is roughly a takeaway pizza per month.
Platforms: Android, iOS, web, Chrome extension.
Bottom line: ChatHub is the right pick when you specifically need to see two answers next to each other.
5. You.com — Best for web-aware research
You.com sits between Perplexity and Poe. The app routes web-search queries through a model of your choice (GPT-5, Claude, Gemini, or You’s own) and lets you toggle between fast, smart, and research modes. Smart mode gives you longer, citation-rich answers, while research mode runs multi-step browsing in the background.
Where it falls short: Research mode can take a minute or two per query. The model picker isn’t as prominent as Perplexity’s.
Pricing: Free for limited queries. You Pro starts in the mid-teens per month.
Platforms: Android, iOS, web.
Bottom line: You.com is the alternative to Perplexity if you want a longer research-style answer by default.
6. DuckDuckGo AI Chat — Best for anonymous quick chats
DuckDuckGo AI Chat strips the model menu down to four (GPT-4o-mini, Claude Haiku, Llama 3.3, Mistral 8x7B) and runs them anonymously. DuckDuckGo proxies the request, so the provider never sees your IP or account. The browser app is the easiest way to fire off a quick prompt without thinking about whether OpenAI is logging the question.
Where it falls short: No flagship models. No image input. The chat history lives inside the browser tab.
Pricing: Free.
Platforms: Android, iOS, web, browser extension.
Bottom line: Pick DuckDuckGo for one-off questions you don’t want tracked.
7. Brave Leo — Best browser-integrated companion
Brave Leo is the AI assistant baked into the Brave browser on Android. It can summarise the page you’re reading, answer follow-ups in context, and switch between Llama 3.3 and Mixtral on the free tier, with Claude available on Premium. Because it lives in the browser sidebar, it skips the copy-paste step you do with most chat apps.
Where it falls short: Leo only works inside Brave. You’re trading browser choice for AI convenience.
Pricing: Free for Llama and Mixtral. Brave Leo Premium adds Claude for a few dollars a month.
Platforms: Android (Brave browser), iOS, desktop.
Bottom line: Brave Leo is the answer for anyone who does most of their AI prompting while already reading a webpage.
How to pick the right one
- If you just want one app: Perplexity (research) or Poe (chat).
- If you want the lowest cost per token: OpenRouter, with any LibreChat-style front end on Android.
- If you care about privacy: DuckDuckGo AI Chat or a self-hosted LibreChat pointing at OpenRouter.
- If you want side-by-side answers: ChatHub.
- If you do most of your prompting while browsing: Brave Leo.
- If you have a heavy GPT-5 or Claude habit and your own API key: OpenRouter saves the most money.
FAQ
What is the cheapest way to use multiple AI models on Android?
OpenRouter, hands down. You pay per token instead of a flat subscription, and the same credit pool covers every model the router supports. Plan on $5-15 a month of usage if you chat moderately.
Can I use ChatGPT, Claude, and Gemini in one app?
Yes. Perplexity, Poe, ChatHub, and You.com all carry GPT-5, Claude 4.7, and Gemini 2.5 in the same interface. Pick based on whether you prefer a search-style UI (Perplexity) or a threaded chat UI (Poe).
Is OpenRouter safe to use?
OpenRouter is a billing and routing layer. Your prompts pass through their servers on the way to the provider, so it carries the same trust assumptions as using any third-party SaaS. They publish a no-training-by-default policy and let you exclude specific providers.
Do I need a Google Play subscription for any of these?
No. All seven let you sign up directly through their website or app store, separate from any Play subscription bundle.
Will these apps work on a tablet?
Yes. Perplexity, Poe, and You.com all have tablet layouts that take advantage of the extra screen. ChatHub’s side-by-side mode is best on a tablet specifically.
