Overview

ChatHub is a multi-LLM comparison platform built around one idea: one question, multiple AI responses. Instead of subscribing separately to each provider, users get access to GPT-5, Claude 4.5, Gemini 3, Llama, Grok, and 20+ other models side by side under a single subscription.

Beyond text comparison, ChatHub adds AI image generation (FLUX.2, Stable Diffusion, Nano Banana), file and document analysis, web search integration, and code preview, with native apps across web, iOS, Android, Windows, and Mac rather than a browser-only tool.

ChatHub targets anyone wanting to compare model outputs before trusting one, already serving 300,000+ active users. Free tier available. Pro: $19/month. Unlimited: $39/month.
