ChatHub is an app for chatting with several AI chatbots at once. A single question goes to multiple models side by side, which helps users spot hallucinations by comparing perspectives. One subscription covers more than 20 models, and the app also handles image generation with models such as Nano Banana, FLUX.2 and Stable Diffusion, file upload and analysis for PDFs and spreadsheets, web search and code preview. It runs as a web app, a browser extension, native iOS and Android apps, and desktop apps for Windows and Mac.
Researchers and analysts who want to cross-check answers before relying on them are a natural audience. Writers and marketers use it to pick the best draft among several models, and developers use code preview and side-by-side output to see which model handles a programming question best. People who follow new model releases use it to test them on their own prompts without juggling accounts. Professionals who work across devices benefit from mobile and desktop apps, and the prompt library helps beginners get started with good prompts. Over 300,000 users have joined.
A researcher asks a hard, context-heavy question and compares how different models reason before choosing an answer. A marketer drafts a product announcement in several models and merges the strongest lines. A student uploads a PDF or spreadsheet and gets analysis from more than one model, while a developer previews and runs code snippets with syntax highlighting. A designer generates artwork and illustrations with several image models in the same app. The built-in comparison topics, such as subjective questions and questions AI still misses, show how models handle culture, ethics and judgment calls.
