What Mammouth does well
- An identified, verifiable French company: Mammouth AI SAS, registered with the Paris Trade and Companies Register under SIREN 932 983 968, with its published head office at 8 rue Dupleix, 75015 Paris
- A public no-training commitment: a dedicated documentation page states that no model is trained on prompts sent through Mammouth, restates each provider’s contractual commitment (OpenAI, Mistral, Anthropic, Google Gemini, Fireworks) and says providers do not retain prompts beyond 30 days
- A clear offer: all three tiers open the same model catalog, and only the usage volume changes (Standard advertised at 3x and Expert at 10x compared with Starter)
- Image and video generation included in all three tiers: Nano Banana, Stable Diffusion, Recraft, FLUX, Sora, Veo and Kling, plus web search through Perplexity
- Documented cross-platform coverage: desktop apps for Mac, Windows and Linux, iOS and Android mobile apps, an OpenAI-compatible API with included credits, and an open-source coding agent (Mammouth Code)
What Moon AI does differently
- Moon AI publishes a list of more than 100 models included in one subscription, including Moon 6, its in-house model; as of August 2, 2026, Mammouth does not give a total count and its pricing page lists 9 text model families and 8 image and video models
- Moon AI applies Moon Blur, two-way reversible masking across more than 150 categories of sensitive data before sending to third-party models, then puts the real values back in the response; as of August 2, 2026, Mammouth’s public documentation does not describe an equivalent mechanism
- Moon AI’s app and storage are hosted by OVHcloud, in Strasbourg and Roubaix; Mammouth states that it processes data in the EEA using PostgreSQL and Google Cloud Platform. In both cases, requests to a third-party model are sent to its provider; at Moon AI, they go through Moon Blur first, which masks the sensitive data it detects
- Moon AI offers a Free plan with no credit card and no commitment; as of August 2, 2026, Mammouth’s pricing page announces neither a free tier nor a trial
- Moon AI includes Word, PDF, Excel and PowerPoint document generation, agents and routines (scheduled or triggered by webhook) and dozens of connectors (Gmail, Slack, GitHub, Notion, Stripe); as of August 2, 2026, Mammouth’s public documentation does not describe these three features, its documented offer covering projects, document analysis, the OpenAI-compatible API and the Mammouth Code agent

Frequently asked questions
How does Moon AI’s price compare with Mammouth’s?
Moon AI’s first paid tier, Lune, is listed at €9.90 per seat per month, VAT included, with 20% off each extra seat in the same workspace. Mammouth’s first paid tier, Starter, is listed at €12 a month with the note “incl. VAT”, so VAT included as well. Moon AI’s higher tiers (Étoile, Constellation, Galaxie, Univers) are detailed on the pricing page.
Does Mammouth have a free plan?
As of August 2, 2026, Mammouth’s official pricing page shows three paid tiers (Starter, Standard, Expert) and announces neither a free tier nor a trial. Moon AI, for its part, offers a Free plan with no credit card and no commitment, so you can try the service before subscribing.
Where is my data processed in each service?
Moon AI’s app and storage are hosted by OVHcloud, in Strasbourg and Roubaix. Requests sent to third-party models go through Moon Blur first, which masks the sensitive data it detects (more than 150 categories in its catalog, and people’s names only if they are in your list of terms), then restores it on return. Mammouth’s privacy policy states that data is processed and stored in the EEA using PostgreSQL and Google Cloud Platform, and covers transfers outside the EEA with Standard Contractual Clauses. In both cases, a request to a third-party model is sent to its provider.
Are my conversations used to train models?
Mammouth publishes a dedicated documentation page stating that no model is trained on prompts sent through its service, restating each provider’s no-training commitment (OpenAI, Mistral, Anthropic, Google Gemini, Fireworks) and saying that providers do not retain prompts beyond 30 days. At Moon AI, the sensitive data detected is masked by Moon Blur before it is sent to the model provider. See the features page for details.
