ChatHub (chathub.gg) — Multi‑Model AI Chat Client and LLM Aggregator
ChatHub is an all‑in‑one AI chat client that lets you prompt once and compare responses from multiple models side by side. It supports popular LLMs such as GPT‑4/4o, Claude 3/4, and Google Gemini under a single, fast interface across web, browser extension, and mobile. The result: quicker evaluation, better prompt iteration, and fewer tabs to juggle for writing, coding, and research.

ChatHub centralizes top AI models in one workspace so you can type once and view answers in parallel. The streamlined UI is built for speed—ideal for content drafting, code help, research summaries, and image prompting. Its feature set includes a prompt library, web browsing, image generation, PDF/image chat, and a lightweight knowledge base via document uploads.
Through a single subscription, ChatHub provides access to a broad set of models (including GPT‑4/4o, Claude 3/4, and Gemini). Power users can compare up to six models at once on paid tiers, accelerate prompt testing, and benchmark output quality and style. See the current catalog on the [models page](https://chathub.gg/models).
Pricing is straightforward: a free tier for basic usage and two‑model compare, with Pro+ and Unlimited expanding limits and bundling premium model access. The same experience extends to mobile via iOS and Android, and a browser extension keeps ChatHub one click away. Details on plans are on the [pricing page](https://app.chathub.gg/pricing).
ChatHub also positions its public Prompt Library as a lightweight “agent” directory—ready‑to‑run prompts and reusable workflows you can share and adapt. Learn how to get started in the [docs](https://doc.chathub.gg) and explore prompts via the [Prompt Library](https://chathub.gg/prompt-library).
