Own-account use relies on the user's existing service privileges and API-key use is pay-as-you-go through the model providers, whose prices are not stated on the listing.

What to know before choosing
Good fit
Users who compare answers across models, power users who already hold model API keys, and users who want past multi-model chats searchable locally.
Limits and trade-offs
Side-by-side comparison is the core value, so single-chatbot-only users gain little; every access route needs an account login, an API key, or a subscription; it is a browser extension workflow, not a standalone app.

A closer look at ChatHub
ChatHub is a browser extension for using ChatGPT, Gemini, Claude, Llama, and more chatbots simultaneously and comparing their responses side by side, accessed through the user's own accounts, API keys, or ChatHub's own AI service, with a prompt library and local searchable chat history.
Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.
When to choose ChatHub
- A user who regularly compares answers across models instead of trusting a single chatbot's response.
- A developer or power user who already holds model API keys and wants them in one side-by-side window.
- A user who wants past multi-model chats searchable locally rather than only in each provider's app.
When to choose something else
- A user who only ever uses one chatbot and never compares responses: side-by-side comparison is the product's core value.
- A user who wants a fully self-contained free chatbot with no account, key, or subscription: every ChatHub route needs one of the three.
- A user who needs a standalone desktop or mobile app rather than a browser extension workflow.
A practical starting workflow
- Install the ChatHub extension in the browser.
- Choose an access route: sign into chatbot accounts in the browser, add API keys, or use ChatHub's AI service.
- Send one prompt and read the chatbots' responses side by side.
- Save useful prompts to the prompt library and search local chat history later.
- Add custom chatbots through any OpenAI-compatible API when a needed model is not built in.
Check before committing
- No subscription amount is stated on the listing read: the listing mentions 'a simple subscription to ChatHub' for its own AI service but gives no price, so price is unconfirmed and no charge fact is recorded.
- Using another service's account or API key inside ChatHub is subject to that service's own plan and terms; ChatHub's listing does not state those third-party prices.
- Chat history is described as saved locally with full-text search; local storage depends on the user's browser and device.
- This page is based on public listing text only (text fetch); the extension was not installed or run.
