The essentials to get started.
What is Moon AI?
Moon AI brings more than 100 models together in one workspace: Moon, Claude, GPT, Gemini, DeepSeek, Llama, Mistral, Qwen and others. Built by Stellarr Studio, it combines chat, documents, media, connectors, agents and routines. The models you can use and your limits depend on the catalog and your plan.
Explore the modelsHow much does Moon AI cost?
A Free plan, with no credit card, lets you try economy and standard models and several tools, with a reduced usage limit. Subscriptions start at €9.90 per person per month, VAT included. Five paid plans, billed per seat, give you more usage and different capabilities.
Compare the six plansWhat is the difference between Normal, Auto and Agent?
Normal lets you choose the model. Auto analyzes your request and picks a model suited to code, writing, reasoning or vision. Agent can plan a task, break it down and chain tools. Web search, images, code and documents stay available in every mode, depending on your plan. Review the results and check important actions.
Understand the three modesHow does Moon Blur protect my data?
Moon Blur’s detection catalog covers 151 categories of data: emails, phone numbers, IBANs, business identifiers, legal or medical data, and technical secrets. The values it detects are replaced with placeholders before your message reaches the model, and can be put back in the answer. Names of people and clients are not detected on their own: from Constellation, add them to your terms to mask. Masking is reversible and may miss things.
How masking worksWhich AI models are available?
The catalog has more than 100 models (107 as of November 5, 2026), including Moon, Claude, GPT, Gemini, DeepSeek, Llama, Mistral and Qwen. A model family comes in several versions: check the ones available in the app’s model picker. The Free plan offers economy and standard models; paid plans open the whole catalog.
Explore the catalogWhere is data processed, and what commitments are published?
The app and storage are hosted by OVHcloud in Strasbourg and Roubaix, France. Model providers and some services may process requests outside the EU, after Moon Blur masking. The DPA, the service’s privacy policy and the legal center describe the GDPR framework and the measures in place. Moon Blur’s detection may be incomplete.
Read the commitments and their limitsWhat kinds of documents can I create?
Moon AI creates 9 formats: PDF, DOCX, PPTX, XLSX, CSV, HTML, TXT, Markdown and JSON. Describe the deliverable you want in plain language, for example a PDF report, a PowerPoint deck or an Excel spreadsheet, then check the file before you share it.
Explore the creation toolsCan I connect my work tools?
Yes. Gmail, GitHub, Notion, Slack, Jira, GitLab, Linear, Google Calendar, Google Drive, Stripe, Sentry, Discord and Telegram are among the supported tools. Lune includes 2 connectors and 3 scheduled routines. Étoile offers 15 connectors, 50 routines, account API keys and Moon CLI. Actions count toward your plan’s usage limit and follow the permissions you grant.
Check each plan’s limitsCan I use Moon on my phone or in the terminal?
The same account works in your browser, on iPhone and iPad from the App Store, on Android from Google Play, and in the terminal with Moon CLI from the Étoile plan. The guides cover installation, Moon Blur, Moon Guard and the CLI commands.

Is Moon AI a French alternative to ChatGPT?
Moon AI is built in France by Stellarr Studio. It is not a model but a platform: it gives you GPT, the model behind ChatGPT, plus more than 100 other models, including Claude, Gemini and Mistral, in one interface. The app and storage are hosted in France; your messages go to the provider of the model you pick, after Moon Blur.
Moon AI or ChatGPT PlusCan I use Claude, GPT and Gemini with one subscription?
Yes. Paid plans, from €9.90 a month VAT included, open the whole catalog of more than 100 models; the Free plan offers economy and standard models. Moon AI gives you access to the models, not to their makers’ apps: features specific to ChatGPT Plus, Claude Pro or Google AI Pro are not included.
Compare subscriptionsWhat does Moon Blur do with my sensitive data?
It masks it before it leaves. Moon Blur replaces the sensitive data it detects with placeholders: IBANs, social security numbers, payment cards, emails, phone numbers, addresses, more than 150 types in all. Your message goes to the model masked, and the real values come back in the answer you read. Names of people are masked with your list of terms, from Constellation; images and voice are sent as they are.
What Moon Blur does not coverIs Moon AI suitable for professions bound by confidentiality?
Moon AI reduces what goes to the model without eliminating it: Moon Blur masks the identifiers it detects, a Confidential Chat is not saved in your history, the app and storage are hosted in France, and a DPA covers professional use. Messages are still sent to the provider of the model you pick: it is up to you to judge what can be shared. Our pages by profession cover the use cases and their limits.
Use cases by professionWhat is the difference between Moon Blur and Moon Guard?
Moon Blur masks sensitive data before it is sent to the model, in the app, the API and Moon CLI. Moon Guard is an optional guard in Moon CLI that blocks destructive commands and the sending of real secrets off your machine; it is off by default.
Moon GuardIs Moon AI related to Moonshot AI or other apps called “Moon AI”?
No. Moon AI is Stellarr Studio’s platform, at realmoon.ai and chat.realmoon.ai, and in the iPhone and Android apps published by Stellarr Studio. Moonshot AI is a different company, which publishes the Kimi models; other apps unrelated to Stellarr Studio also use the name “Moon AI”.
