ChatHub

ChatHub is an app for using multiple AI chatbots at the same time, side by side. Its homepage shows GPT-6, Claude 5, and Gemini 3 together, and its FAQ says ChatHub currently supports GPT-6, Claude 5, Gemini 3, Llama 4, and over 20 more chatbots. The vendor reports more than 300,000 users. Instead of asking one model and accepting a single answer, you ask once and compare how several models respond. The core feature is one question with multiple AI responses. ChatHub explains the reason plainly: any single AI can hallucinate, so getting multiple perspectives helps you gain confidence in an answer and spot where models disagree. The same comparison approach extends to other work. AI image generation lets you create artwork, illustrations, and photos with models including Nano Banana, FLUX.2, and Stable Diffusion, among other leading image models named on the page. File upload and analysis lets you upload documents, images, and other files for AI-powered insights, including analysis of PDFs and spreadsheets. Around the chat itself, ChatHub adds Web Search for real-time information from the web, Code Preview to view and execute code snippets with syntax highlighting and a live preview, a Prompt Library with a curated collection of prompts for various use cases, and AI Tools covering translation, web summarization, and other productivity tasks. You can explore on the homepage how different models answer hard comparison questions before you start your own session. ChatHub is available as a web app and a browser extension, with native iOS and Android apps and desktop applications for Windows and Mac also listed, and the FAQ confirms you can use it on mobile through the web app. It suits people who already move between ChatGPT, Claude, and Gemini and want those conversations in one interface, as well as anyone who wants a second or third model view on an important question, a document analysis, or a piece of code before relying on the result. User accounts quoted on the homepage describe the same workflow in practice: comparing responses in one place, picking the strongest answer, and using the contrast between models to decide which chatbot fits a specific use case.
