ChatHub - 2026 Pricing, Features, Reviews & Alternatives

ChatHub is an all-in-one AI client available as a web app, browser extension, and native desktop and mobile apps for Windows, macOS, iOS, and Android. It provides access to 20+ large language models, including GPT-5, Claude 4.5, Gemini 3, Llama 3.3, DeepSeek R1, Mistral, and Grok, through a single subscription or via user-supplied API keys. Up to six models can be queried simultaneously from a single prompt, with responses displayed side by side for direct comparison. A summarize-and-compare feature synthesizes outputs from multiple models in one click. AI image generation is supported via FLUX.1 and GPT-4o image models. Additional capabilities include image upload with text extraction, document upload for context-aware chat, voice input, a web access plugin for real-time internet search, webpage summarization, and AI translation.

ChatHub targets individual users, productivity-focused professionals, developers, and researchers who rely on AI chatbots regularly and need access to multiple models without managing separate accounts or subscriptions. A prompt library supports saving and reusing prompts, while local chat history with full-text search keeps past conversations accessible. Code preview supports HTML and Mermaid diagrams, and markdown rendering with code highlighting is included. Custom chatbots can be configured via any OpenAI-compatible API. The platform suits general consumers through advanced technical users, with a free tier available and premium plans offering higher usage quotas and access to the latest models as they are released.
