ChatHub

In your browser, ChatHub puts several AI chatbots side by side so you can send one prompt and read the answers next to each other.

ChatHub is a browser extension and AI chatbot aggregator that compares responses from multiple large language models in a single interface.

Checking one model against another is the main point: if two bots disagree, you spot it right away instead of trusting a single answer.

Beyond comparison, ChatHub lets you store and reuse prompt templates, build custom chatbots for specific needs, and search the full text of your chat history to find an old conversation.

Real-time web access keeps answers current.

Advanced models need your own API key or an AI account.

How many chatbots you can run at once depends on your subscription tier.

The lifetime plan only works with the browser extension version, so check that before you pay for it if you want anything else.
