Anyone who uses AI at work knows the routine. One model for drafting, another for coding, a third for research, each with its own login, its own bill and its own tab. A growing group of “AI super apps” wants to replace that juggling with a single window where you can ask a question once and compare answers from several models.

They are not all the same product. Some are polished consumer subscriptions, some live in your browser, and some are built for developers who pay per use. Here are eight, grouped by who they suit.

For people who want one subscription

1. AI Fiesta. Launched in August 2025 as an India-focused subscription, it opened with six models and a ₹999-a-month price, paid by UPI, according to launch coverage by Storyboard18 and exchange4media. That coverage described it as a tie-up between YouTuber Dhruv Rathee and TagMango founders Divyanshu Damani and Mohammad Hasan.

Its website now claims more than 100 models from nine providers, and lists Compare Mode (ask once, review several answers), Consensus (one answer built from where models agree, with disagreements flagged), a prompt enhancer, Deep Research, and tools for images, video, websites and slides. It also has an Auto Mode that picks a model for each question. Plans are priced in dollars: Basic at $12 a month and Pro at $29 a month, with usage caps on tokens and on each creation tool. The company claims 1 million-plus users, which we could not verify.

2. Poe. Built by Quora, Poe opened to the public in February 2023. It offers models from several providers plus a large set of user-made bots, and lets creators build and publish their own. Subscribers get access to advanced models within usage limits, so heavy use of the top models can run out. Check Poe’s current plans before relying on it.

3. ChatHub. Its main trick is simplicity: send one question to several chatbots and read the answers side by side. It runs as a web app, a Chrome extension, and on iOS, Android, Windows and macOS. Its pitch is that comparing answers helps catch the errors any single model can make. You can start free, and heavier use needs a premium plan.

For people who live in the browser

4. Monica. Available on the web, as Chrome and Edge extensions, and as desktop and mobile apps, Monica combines model access with page and video summaries, translation, a writing assistant with more than 80 templates, search and image generation. It can be used free with a daily limit, with paid upgrades for more.

5. Merlin. A Chrome extension and web app that opens on any site with a keyboard shortcut. It summarises pages, articles and YouTube videos, drafts Gmail replies and social posts, and can use uploaded PDFs as context. It has a free tier with a daily limit and a paid Pro plan. The model list and prices on its page looked dated, so check them before you subscribe.

For research and developers

6. You.com. It began as an AI search engine and was included in the original list for its mix of search and model access. Its website now leads with search, content and research APIs for developers and AI agents, with enterprise security features such as zero data retention and SOC 2 certification. If you want a consumer chat app, check what it currently offers.

7. OpenRouter. This is a gateway rather than a consumer app. It lists more than 500 models from more than 80 providers behind one interface, billed from credits you buy, with no subscription. It suits developers and technical users who want to try many models and pay for what they use.

8. TypingMind. You bring your own API keys and pay the model providers directly, while TypingMind sells a one-time lifetime licence for the interface. It supports chatting with several models in parallel, projects, file chat, web search and plugins, and says data is stored locally on your device by default. It suits people comfortable managing API keys who want control over cost and privacy.

How to choose

• One bill, little setup: a subscription app such as AI Fiesta, Poe or ChatHub.
• AI while you browse: Monica or Merlin.
• Pay only for what you use, or build products: OpenRouter or TypingMind.
• Search-led research: You.com, though check its current consumer offering.

Things to check before you pay

Multi-model apps may not match the full features of each provider’s own app. One third-party review of Poe, for instance, warns that it may not have the latest features of each AI. Usage is usually capped by tokens, points or daily queries, and premium models often use up your allowance faster. Prices and model lists change quickly, so confirm them on each platform’s own site. And a side-by-side answer is a useful check, not proof that any of the answers is right.
