Mammouth is a French chat app that bundles text, image, video and music models from many AI companies into one subscription, with usage limits that renew every few hours. There is no free plan, and the paid plans differ mainly in how much you can use per session. What decides whether it suits you is whether you want to pick a different model for each message and pay one price for all of them.
What is Mammouth?
Mammouth is made by Mammouth AI SAS, a company based in Paris, France. It runs in the browser, installs as a web app from the browser on Windows, Mac and iPhone, and has an Android app on the Play Store.
Mammouth has no models of its own. Every model in it comes from another company, including open models such as DeepSeek, Kimi and GLM. The interface is available in English, French, Italian, Spanish, German, Dutch, Polish, Romanian, Portuguese and Catalan.
What you can do with Mammouth
You type a message and pick the model to answer it, and you can resend the same prompt to another model to compare. The text models include Claude Opus 5.5, Claude Sonnet 5.5, Claude Haiku 5.5, Claude Fable 5.1, GPT-6.1 Sol, GPT-6 Luna, GPT-6 Astra, Gemini 4 Argon, Gemini 3.8 Flash, Mistral Large 4, Grok 4.7, Kimi K3, GLM 5.3, Qwen 3.8 and DeepSeek v4.1 Flash, and reasoning models are included on every plan.
Web search runs through Perplexity, ChatGPT Search and Gemini Grounding, and Deep Research comes on every plan. Voice chat lets you talk to Mammouth, and it can search the web while you talk. Agentic Mode, switched on from the input area, handles bigger jobs such as generating and editing documents and running deep, documented web searches.
Images come from Nano Banana 2.1, GPT Image 2.5, FLUX, Recraft and Stable Diffusion, video from Veo and Kling, and music from Lyria. Files of almost any kind can go into a chat, including documents, spreadsheets, presentations, code, images, audio and video, up to 50 files and 100 MB per conversation and 4,000,000 characters of document content per request.
Projects in Mammouth are called mammouths. Each one groups your conversations by theme, with its own instructions, files and default model. Pre-built connectors link Mammouth to Microsoft 365, GitHub, Notion and Atlassian's Confluence and Jira, you can add your own MCP servers, and documents can be uploaded from Google Drive or Dropbox.
Working with other people
Team plans come with an admin console to invite members and manage licenses, centralized billing and shared projects. A mammouth can be shared with the team as read-only or editable.
Mammouth also offers an OpenAI-compatible chat completion API for building AI into your own applications. Every subscription includes monthly API credits, and more can be bought.
Mammouth pricing: what each plan gives
Mammouth has no free plan. Usage limits are set per session and fully renew after 3 hours. Starter is the reference quota, Standard gives three times as much and Expert ten times as much. When you reach a model's quota, Mammouth switches you to a lighter model rather than stopping.
Starter costs $12 a month, or $10 a month billed yearly ($120 a year), with $2 of API credits a month. Standard costs $24 a month, or $20 a month billed yearly ($240 a year), with $4 of API credits. Expert costs $72 a month, or $60 a month billed yearly ($720 a year), with $10 of API credits. These prices exclude VAT; European visitors pay the same figures in euros, including VAT, from €12 a month.
Team plans cost the same per user as the individual plans, and a team can mix them. Enterprise, with single sign-on and custom onboarding, is priced on request.
Privacy and security
Mammouth does not train on your conversations: "We don't train any internal models, and we never use your conversations to train anything." The model providers never train on prompts sent through Mammouth either.
Mammouth is committed to protecting your personal data in accordance with the GDPR, and your data is processed and stored in the European Economic Area. Single sign-on works with Microsoft Entra ID, Okta, Keycloak and other SAML 2.0 identity providers for companies or universities with more than 50 licenses. Support runs by email, through a documentation site with an FAQ and in a Discord community.
Who Mammouth suits
Mammouth suits people who want text, image, video and music models from many companies in one place and like comparing answers by resending a prompt to another model. European users and teams get data kept in the European Economic Area, a commitment that conversations are not used for training and prices shown in euros.
It suits less well anyone who wants to try it for free, since there is no free plan. Heavy users of one model should know that quotas are set per session and that Mammouth moves you to a lighter model once a quota runs out, and single sign-on needs more than 50 licenses.
