ChatHub

ChatHub is a multi-model AI chat app that sends one prompt to several chatbots at the same time and shows their answers side by side. Instead of opening tabs for ChatGPT, Claude and Gemini, you ask once and compare up to six responses in a grid. That focus on comparison is its identity, and its site cites more than 300,000 users.

What is ChatHub used for?

ChatHub is used to cross-check answers, pick the best draft, and learn which model suits which task.

• Asking GPT, Claude, Gemini, Llama and 20+ other models the same question at once
• Comparing answers to catch hallucinations or weak reasoning
• Generating images with Nano Banana, FLUX.2, Stable Diffusion and others
• Uploading PDFs, spreadsheets and images for analysis
• Getting live information through web access and previewing code
• Saving prompts in a library and summarizing long chats

Who ChatHub is best for

ChatHub suits writers who want several drafts to choose from, researchers and students who want to verify answers, developers comparing models for a project, and anyone curious about how models differ. It is less useful for people who just want one assistant with deep features like long-term memory or agent workflows.

ChatHub pricing

ChatHub lets you start for free, with limited usage before upgrading. On the official pricing page as of October 2026, ChatHub Pro is $14.99 per month billed annually and includes 10,000 basic model queries, 1,500 advanced model queries, 3,000 credits and 300 document uploads each month. ChatHub Unlimited is $24.99 per month billed annually with unlimited basic and advanced model queries, 10,000 credits and unlimited document uploads. Monthly billing costs more; the page lists Pro at $19 and Unlimited at $39 before the annual discount. Paid plans work across the extension, web app and mobile apps without your own API keys. The browser extension's older lifetime license is no longer needed, since the extension is now free.

Limitations to keep in mind

• Running several models per prompt uses up quotas faster
• Pro caps advanced model queries at 1,500 per month
• Comparison is the core strength; agent and automation features are lighter
• Side-by-side layouts are cramped on phone screens

ChatHub vs alternatives

Poe is the better pick if you want many models and community-made bots in one app with a free tier, though it focuses on one model per chat. Sider and Monica are browser sidebars that help while reading and writing on any web page. Merlin AI offers a similar browser-first assistant. ChatHub wins when your main need is asking several top models the same question and comparing answers at a glance.

Tips for getting started with ChatHub

Limit comparisons to two or three models for everyday questions and save six-way grids for important decisions. Use the prompt library to store prompts you reuse, so each comparison starts from the same input. Upload the same document to several models when checking summaries, since differences reveal what each one missed.
