ChatHub
ChatHub is an all-in-one AI chat client that puts GPT-5, Claude 4.5, Gemini 3, and 30+ other models in one interface. You ask a single question and read answers from multiple chatbots side by side, which helps when one model hallucinates or misses context. It runs as a web app, native iOS and Android apps, Windows and macOS desktop builds, and a Chrome extension with 200,000 users.
Most AI tools lock you into one provider. ChatHub is built around comparison instead: you see how GPT-5, Claude, Gemini, DeepSeek, Grok, and others answer the same prompt before you commit to a reply. That side-by-side layout is the core workflow, not an add-on feature buried in settings.
It fits developers testing model behavior, writers shopping for the best draft, and researchers who want multiple perspectives without juggling tabs. You can bring your own ChatGPT or Claude login, plug in API keys, or subscribe to ChatHub Cloud for ready access to premium models. Built-in tools cover image generation, PDF analysis, web search, translation, and a searchable prompt library.
