How we grade them
| 3.4GPAChatHubVery good | 2.6GPAMammouthGood | |
|---|---|---|
| Value for money | BPro is $14.99 a month billed annually, or $19 monthly, for 10,000 basic and 1,500 advanced model queries, 300 document uploads and the premium features. That's the going rate, though here it covers many models. Unlimited is $24.99 a month billed annually, or $39 monthly. | BStarter is $10 a month if you pay for the year, or $12 monthly. That's about the going rate for an AI assistant, and here it covers models from several makers at once. Usage is rationed though, with quotas that renew every 3 hours, and the dollar prices leave out VAT. |
| Free plan and trial | BRegistering for the web app gets you a free usage quota, but ChatHub doesn't say how big it is. The browser extension is free on your own accounts or API keys. Web access, file uploads and the other premium features need a paid plan. | FNothing is free. There's no free plan, and the pricing page lists no trial either, so finding out whether you like it costs at least one month at $12. |
| Features | AOne prompt to up to six chatbots, answers side by side. Premium adds real-time web access and chat with images, PDFs and spreadsheets, and there's image and video generation on monthly credits. Plus a prompt library, full-text search of your history and one-click summaries. | AText models from OpenAI, Anthropic, Google, Mistral, xAI and DeepSeek, web and deep research, image, video and music generators, voice chat, and custom assistants that keep your instructions and files. Every plan includes API credits and a coding tool too. |
| Ease of use | BType once, read six answers. The paid plans need no API keys, so there's nothing to wire up first. There's no App Store rating on record for it, so it stops at a B. | BIt opens in a browser, and resending a prompt to another model is one click. There's no App Store app, so we have no rating on record to show how people get on with it. That stops it at a B. |
| Platforms and integrations | AA web app, a Chrome extension, Windows and Mac apps, iPhone and Android. The extension also takes custom chatbots for any OpenAI-compatible API, such as OpenRouter or Ollama, though that part is extension only. | BWeb and an Android app, with connectors for Microsoft 365, GitHub, Notion and Atlassian, and an API. But it isn't in the App Store: on iPhone, Mac and Windows you install it from the browser as a web app. |
