How we grade them
| 2.6GPAMammouthGood | 2.8GPAT3 ChatGood | |
|---|---|---|
| Value for money | 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. | BWe can't tell you what it costs. The terms say usage beyond the free limits is charged, but the prices only appear in the app's settings and couldn't be read for this listing. With no price on record, it stops at a B. The terms also say no refunds when you cancel. |
| Free plan and trial | 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. | BThe terms of service say it's free up to certain usage limits. Those limits are shown only in the app's settings, so we can't tell you how far free goes. When your quota runs dry, you wait for the refill. |
| Features | 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. | BModels from OpenAI, Anthropic and Google, with others through OpenRouter, and you set the model and its reasoning effort per chat. Add web search, PDF and image attachments, profiles and temporary chats. The listing shows no image generation, voice or agent tools. |
| Ease of use | 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. | BIt's a chat window in a browser, with nothing to install. The usage meter takes a minute to get: one bucket refills every 4 hours, and a second on your monthly renewal date. There's no rating on record to go by, so a B. |
| Platforms and integrations | 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. | CA web app, and that's all the pages we could read describe. No desktop or phone apps are mentioned, and the listing shows no API and nothing that hooks it up to your other tools. |
| Best for | GPT, Claude and Gemini on one bill | several labs' models in one browser tab |

Worth knowing
Mammouth
- There is no free plan, and the pricing page lists no free trial.
- Usage is limited per session and quotas renew after 3 hours. At a model's limit Mammouth switches to a lighter model.
- There is no App Store app: on iPhone, Mac and Windows it installs from the browser as a web app. Android has a Play Store listing.
- Prices are shown in euros or US dollars depending on the visitor's country, and dollar prices exclude VAT. Paying by bank transfer needs an annual commitment.
T3 Chat
- Prices and usage limits are shown only in the app's settings page and could not be read for this listing.
- Usage is metered: long threads, attachments, search and costlier models drain the quota faster, and when both buckets are empty you wait for a refill.
- The terms of service say no refunds are given when you cancel your account.
- The pages that could be read describe a web app only; no desktop or mobile apps are mentioned.
Key features
Mammouth
- Many models in one subscription
- One plan covers text models from OpenAI, Anthropic, Google, Mistral, xAI, DeepSeek and others, with Perplexity for web and deep research. The default model in each category can be reordered.
- One-click reprompting
- Send a prompt, along with the conversation history, to another model to compare or complement the answer without retyping it or opening a new chat.
- Image, video and music generation
- Image models include Nano Banana, GPT Image, FLUX, Recraft and Stable Diffusion. Video runs on Veo, Kling and Grok Imagine, and music on Lyria.
- Custom mammouths
- Custom assistants keep instructions and files for reuse across conversations. In a team they can be shared with read-only or edit access while conversations stay private.
- Voice chat, dictation and read-aloud
- Hold a real-time voice conversation and get a transcript afterwards, dictate a message as text, or have any answer read out with text-to-speech.
- Connectors, API and Mammouth Code
- MCP connectors link Microsoft 365, GitHub, Notion, Atlassian or a custom server to the chat. Every plan includes monthly API credits and the Mammouth Code tool for developers.
T3 Chat
- Models from several providers
- Runs models from OpenAI, Anthropic and Google and routes others through OpenRouter. The model and its reasoning effort are chosen per chat.
- Web search
- Search can be switched on for a chat so that answers draw on more recent results, with between 1 and 5 search queries or tool calls allowed per run.
- Two-bucket usage meter
- Usage is spent from a Base bucket that refills every 4 hours, then from an Overage bucket that refills on the monthly renewal date. Settings show each as its own percentage bar.
- File and image attachments
- Prompts can include uploaded PDF files, images and text files. Large or numerous attachments raise what a message costs against the usage meter.
- Profiles and temporary chats
- A chat can be started under a named profile, or as a temporary chat that is not kept as a saved thread. A /new URL with query parameters presets the prompt, model and search setting.
- Training opt-outs
- T3 Chat says it does not train its own models and has opted out of training-data collection with its providers where possible. Models that require training are labeled.
