About
ChatHub is a multi-AI platform that allows users to interact with and compare responses from the world's leading AI chatbots — including GPT-5, Claude 4.5, Gemini 3, Llama 3.3, and over 20 more models — all within a single, unified interface. Instead of switching between tabs or subscriptions, ChatHub consolidates access to the best AI models under one roof, making it easy to identify which model performs best for any given task. The platform goes beyond simple chat: users can generate images with models like FLUX.2 and Stable Diffusion, upload and analyze documents (PDFs, spreadsheets, and more), perform real-time web searches, and preview and execute code snippets with syntax highlighting. A built-in Prompt Library offers curated prompts for a wide variety of use cases, while AI-powered tools for translation and web summarization further extend productivity. ChatHub is trusted by over 300,000 users and is accessible across every major platform — web browser, Chrome extension, iOS, Android, Windows, and macOS. The freemium model allows anyone to get started for free, with a premium plan unlocking expanded usage and advanced features. Whether you're a developer evaluating LLM outputs, a marketer drafting copy, or a knowledge worker seeking reliable AI answers, ChatHub provides a powerful, streamlined workflow for multi-model AI usage.
